How To Calculate Electric Trolling Motor Runtime?

Leave a Comment / Lifepo4 Lithium 12v 48v Battery /

Electric trolling motors are commonly rated in horsepower (HP), with one electrical HP equivalent to 745.7 watts (W). A 1 HP motor “cannot” use less than 746W (rounded). Taking into account the prop drive shaft and system losses, if the motor draws 1000W, it would have an efficiency of 75%. When calculating your battery energy storage needs, it is essential to consider the motor and system efficiency. While horsepower represents power, kilowatt-hours measure energy. To convert from horsepower to kilowatt-hours, you need to know the duration of power usage.

Therefore, the general power conversion formula from HP to required watt-hours (Whr) of energy storage is HP divided by motor efficiency times 746.

For example, a 1 HP motor operating at 75% efficiency would require 994.66 Whr of energy to run for one hour (1 HP / 0.75% x 746W = 994.66 Whr).

To determine the battery capacity needed to meet your expectations, the next step is to convert HP to amps (A). Since HP is a measure of electric power equal to 746W per horsepower, you can calculate amps by dividing the Whr result by the system operating voltage using Ohm’s Law: Amps x Volts = Watts or Watts / Amps = Volts.

At 12V, the amp draw would be (1 HP / 0.75% x 746W = 994.66 Whr / 12V = 82.8A). If you wanted to operate a 1 HP 12V trolling motor for 1 hour, you would need an 82.8AH 12V energy (battery) source.

At 24V, the amp draw would be (1 HP / 0.75% x 746W = 994.66 Whr / 24V = 41.4A). If you wanted to operate a 1 HP 24V trolling motor for 1 hour, you would need a 41.4AH 24V energy (battery) source.

At 36V, the amp draw would be (1 HP / 0.75% x 746W = 994.66 Whr / 36V = 27.6A). If you wanted to operate a 1 HP 36V trolling motor for 1 hour, you would need a 27.6AH 36V energy (battery) source.

At 48V, the amp draw would be (1 HP / 0.75% x 746W = 994.66 Whr / 48V = 20.7A). If you wanted to operate a 1 HP 48V trolling motor for 1 hour, you would need a 20.7AH 48V energy (battery) source.

It becomes evident that higher operating voltage results in lower amp draw. This information is crucial in determining the size and voltage of the trolling motor and the battery required to achieve your desired runtime.

To calculate electric trolling motor runtime, you need to know the Amp Hour (AH) rating of your battery bank and the motor’s average amp draw: AH Battery Rating / Amp Draw = Run Time.

It is important to note that a deep-cycle battery maintains its operating voltage better than a dual-purpose or starting battery. Additionally, lithium batteries maintain a high voltage without sagging, preventing the motor from drawing excessive amps. As voltage drops, the amp hour draw increases (Ohm’s Law). High-quality deep-cycle lead-acid batteries should not be discharged below 50% to 80% to avoid damage. Similarly, dual-purpose lead-acid batteries should not be discharged beyond 17.5% to 30%, and starting lead-acid batteries should not be discharged below 1% to 3%. However, lithium batteries can be discharged to 100% Depth of Discharge (DoD) without consequences.

Determining the appropriate size of the trolling motor:

To determine the right trolling motor for your boat, you need to calculate the required thrust to propel the boat. Thrust is measured in pounds (lbs.) and indicates the power of the motor. It is similar to torque in a car, determining pulling force rather than speed. Generally, larger and heavier boats require more thrust. Thrust becomes particularly important when using GPS functionality to fix your position or follow a specific course.

What battery for trolling motor

Get the most out of your trolling motor by choosing the right battery. Deep cycle batteries, particularly marine deep cycle batteries, are perfect for consistent power over a longer time. But how do you choose the right battery?

Consider the battery capacity, measured in ampere-hours, based on the needs of your trolling motor. Higher capacity equals longer usage time. Lead-acid batteries are traditional and affordable but require maintenance. On the other hand, AGM batteries are spill-proof and have better resistance, but cost a bit more. Lithium-ion batteries are lightweight and have a longer lifespan with faster recharging, but tend to be more pricey.

Keep in mind your budget, desired runtime, weight requirements, and charging capabilities, along with referring to your trolling motor’s specifications. With these factors in mind, you can select the perfect battery for your trolling motor and optimize your performance.

Marine House Battery Bank For Power Or Sailing Vessels

Leave a Comment / Lifepo4 Lithium 12v 48v Battery /

Seastar Battery, a prominent lithium battery manufacturer based in Shenzhen, China, The article focuses on the use of Lifepo4 Start batteries in marine house battery banks for power or sailing vessels.

Marine House Battery Bank For Power Or Sailing Vessels

The electrical system of a cruising powerboat or sailing vessel relies on a dedicated bank of “House” batteries, specifically designed for deep cycling. These batteries provide power to essential equipment such as GPS devices, electronics, radios, cabin and navigation lights, water systems, head and bilge pumps, as well as other dual power (AC/DC) appliances like refrigeration units. The AC system, on the other hand, is powered by either shore power or an onboard generator, supporting devices such as electric stoves, ovens, TVs, cabin heaters, and HVAC units. Inverter chargers can also power dual-power AC/DC refrigeration systems and straight AC loads like microwaves and TVs.

The house batteries are charged by the alternator, typically after the starter batteries have been fully charged. When the vessel is connected to shore power or the generator is running, any excess AC power is automatically shared with the inverter charger to recharge the 12-volt house battery system. It is crucial for the house batteries to support the surge current required by the inverter during load start-up. Monitoring the State of Charge (SoC) becomes highly beneficial in this context.

The starting batteries, responsible for consistently delivering high Cold Cranking Amps (CCA), need to withstand varying temperatures and vibrations. In addition to cranking the engine, they must possess High-Cycle Reserve Capacity (RC) to support special equipment such as winches and thrusters when the engine is off. The engine alternator serves as the primary charging source for the starting batteries unless an independent shore-powered battery charger is installed. House batteries can often be connected to the engine for emergency starting. In marine applications, maintenance-free spill-proof batteries are highly desirable.

Deep Cycle battery specifications include Amp-hours (Ah), indicating the current a battery can deliver for 20 hours at a constant discharge rate until the voltage drops to 10.5 volts. Cycle Life refers to the number of charge and discharge cycles a battery can withstand before its capacity drops below 50%. Deep cycle batteries excel in this regard compared to starting batteries or dual-purpose batteries, which deteriorate quickly when subjected to deep discharges beyond their intended capacity. Starting batteries are designed for shallow repeated discharges of 1-3% Depth of Discharge (DoD), while dual-purpose and high-cycle batteries can handle repeated discharges of 17.5-30% DoD. Deep Cycle batteries, depending on the technology used, can withstand repeated depths of discharge ranging from 50% to 80% DoD.

The most common causes of lead-acid battery failure in marine applications are acid stratification, extreme temperatures, and damaging vibrations. Acid stratification, which occurs naturally in flooded lead-acid batteries, results in reduced capacity and charge acceptance. Utilizing AGM technology or employing acid mixing technology in flooded lead-acid starting batteries helps mitigate acid stratification. For flooded lead-acid deep cycle house batteries, AGM technology or equalization charging by the inverter charger can effectively address acid stratification.

Seastar Battery is committed to providing high-quality Lifepo4 Start batteries that meet the demanding requirements of marine house battery banks, ensuring reliable power supply and optimal performance for power or sailing vessels.

Understanding the Recharging Process of Lead-Acid Batteries

Leave a Comment / Lifepo4 Lithium 12v 48v Battery /

Seastar Battery, a distinguished lithium battery manufacturer in Shenzhen, China, seeks to provide valuable insights to international buyers and importers regarding the recharging process of lead-acid batteries.

HOW DOES A BATTERY RECHARGE?

The recharging process for lead-acid batteries, including flooded, gel, and AGM types, follows a consistent pattern.

During discharge, the material on both plates of the battery is converted into lead sulphate (PbSO4). When a charging voltage is applied, the opposite reactions occur, reversing the discharge process.

Charge flow takes place as electrons move within the metal components, while ions and water molecules move within the electrolyte.

Chemical reactions transpire at the positive and negative plates, converting the discharged material back into charged material. The positive plates are transformed back into lead dioxide (PbO2), while the negative plates are converted back into lead (Pb) during the charging process.

Sulfuric acid is generated at both plates, and water is consumed at the positive plate. If the voltage exceeds the optimal level, additional reactions occur: Oxygen is separated from water molecules at the positive plates and released as a gas, while hydrogen gas is released at the negative plates. However, if oxygen gas can reach the negative plates first, it recombines into water (H2O). Battery “gassing” occurs near the end of the charge when the charging rate becomes too high for the battery to handle.

To mitigate excessive gassing, a temperature-compensating voltage-regulating charger is employed. This charger automatically reduces the charge rate as the battery nears its fully charged state. Charging batteries for extended periods at high rates that cause excessive gassing should be avoided. In sealed valve-regulated batteries, water cannot be replaced, making it crucial to prevent overcharging, even at low rates commonly referred to as “trickle charges.”

In a fully charged battery, the majority of the sulphate exists as sulfuric acid. As the battery discharges, some of the sulphates begin to form on the plates as lead sulphate (PbSO4). Consequently, the acid becomes diluted, leading to a drop in specific gravity as water replaces more sulfuric acid. A battery that remains in a discharged state or is continually undercharged will experience premature failure. This condition is commonly known as sulfation.

Seastar Battery remains committed to manufacturing high-quality lead-acid batteries, ensuring optimal performance and longevity for various applications

How can I determine if my deep-cycle battery has reached the end of its useful life?

Leave a Comment / Lifepo4 Lithium 12v 48v Battery /

Determining the end of a battery’s useful life can be a challenging task. It depends on the test standard or the specific application the battery is being used in, leading to various answers to this question.

The battery industry has numerous test standards that correspond to different battery types and applications. Regardless of the test standard used, if the battery no longer meets the required service level for its initial intended purpose, it can be considered at the end of its useful life from the perspective of your specific application. service level for its initial intended purpose, it can be considered at the end of its useful

However, it is important to note that this determination may differ from the manufacturer’s or industry engineering standard’s definition of the battery’s useful life.

Cycle Life Testing Standards at Various Rates and Remaining Capacities

According to the Seastar Battery BCI Standard, a deep-cycle battery would be considered at the end of its life if it fails to deliver at least 50% of its original rated capacity when tested at its 2-hour rated capacity while maintaining a voltage above 1.75 volts per cell (5.25 volts for a 6-volt battery, and 10.5 volts for a 12-volt battery).

For instance, in the case of a golf cart battery used in golf carts, if it cannot sustain a minimum voltage of 1.75 volts per cell (5.25 volts) for 40 minutes under a 75-amp load, it would be determined to have reached the end of its life.

Most official battery cycle life tests are conducted in controlled laboratory environments with specific conditions and temperatures.

As a quick non-scientific rule of thumb test that average users can perform, follow these steps:

Ensure the battery is fully charged to approximately 2.13 volts per cell (6.4 volts for a 6-volt battery and 12.8 volts for a 12-volt battery).
Apply a load using a carbon pile (preferred) or a resistive load tester capable of providing a meaningful load of 3 to 4 times the battery’s amp-hour (AH) capacity or two times the reserve capacity rating.
If the battery maintains a voltage above 9.6 volts for 30 seconds, it is still usable. However, it may not be capable of meeting your required runtime.

Everything You Need to Know About Battery Voltage: A Complete Guide

Leave a Comment / Lifepo4 Lithium 12v 48v Battery /

Battery voltage can be a confusing topic. We’re all familiar with the 1.5-volt AA battery, the 12-volt car battery, or the 24-volt deep cycle battery. But what does it all mean? And is there any danger we should be aware of? In this pillar content, we’ll break voltage down for you, exploring what it is, how we measure it, and the science behind it. Gain a deeper understanding of battery voltage now.

Discover the Basics of Battery Voltage

It’s the measure of electrical potential between the positive and negative terminals. Essentially, it’s the force that pushes electrons from one point to another. The greater the difference in potential charge, the higher the voltage. Take a battery as an example: the negative terminal has an excess of electrons, while the positive terminal lacks electrons. The number of electrons in the negative terminal compared to the positive terminal determines the voltage.

Discover the Magic Behind Generating Battery Voltage

Batteries are made up of four essential parts – the negative anode (often zinc, lithium, graphite, or platinum), the positive cathode (typically oxidizing metals like lithium oxide, copper oxide, or graphite oxide), the electrolyte, and the separator. But how do these parts work together to create the voltage that powers our devices? Find out how the circuit connects them to allow electrons to flow and create that vital energy supply. Get ready to add to your knowledge with our comprehensive guide to batteries.

Discovering the Fundamental Difference between Voltage and Current

Understanding the concepts of battery voltage and current may seem puzzling, but it’s incredibly simple. Volts measure the potential energy stored in a battery, which experts and manufacturers match with electronic devices. On the other hand, current measures the speed of electron flow, quantified in amps. The higher the amperage, the quicker the electrons flow. Get a grip on the difference between these two important electrical properties!

Unveiling the Secrets of Battery Voltage Measurement

To make sure your battery stays in tip-top shape, it’s crucial to know its current state of charge. Luckily, two technologies can help a multimeter or a battery monitor like the Victron Energy Battery Monitor BMV-712.

These handy devices measure electrical potential differences and display the corresponding voltage number on a screen. With the power of accurate voltage readings, you’ll always be on top of your battery’s performance.

Discovering the Essentials: Normal Voltage Explained

The voltage of a battery depends entirely on its chemistry. While batteries with the same chemistry produce the same voltage, different chemistries can produce vastly different voltages. For example, a car battery might have a voltage of 12.6 volts, while a AAA battery typically only has a voltage of 1.5 volts.

Not all batteries are created equal, however. Higher-voltage batteries, like a 12V battery, contain multiple cells arranged in series to boost the overall voltage. In contrast, a AAA battery contains just one cell. Understanding the voltage of your battery is important for selecting the right electronics to power and avoiding potential damage.

Join us as we explore the science of voltage and how it affects your battery’s performance. Learn about the chemical reactions that create voltage, the importance of correct voltage matching, and how to select the right battery for your needs.

Lead-Acid vs. Lithium Battery Voltages

Did you know that the voltage of your battery changes depending on its level of charge? When fully charged, a battery is able to deliver a higher voltage than when it’s nearing empty.

But here’s the catch: not all batteries are created equal. For instance, lead-acid batteries experience much larger voltage drops compared to lithium batteries due to their advanced technology.

To put things into perspective, a 12-volt lead acid battery will only deliver 11.6 volts at 20% capacity. In contrast, a lithium battery packs in more energy density and can still deliver 12.9 volts even at 20% capacity.

So if you want to stay powered up and on the go, understanding battery voltage is key. Start with these insights and become a battery expert today.

Is Battery Voltage a Safety Hazard?

Are you concerned about battery voltage risks? According to OSHA standards, you have nothing to worry about until it exceeds 50 volts. But why does this matter?

Well, 50 volts is deemed safe for the human body since it’s a level of shock that won’t harm you, even with unlimited current capacity. The theory is based on the distribution of power in the human body, which shows that the arms and legs are at least 500 ohms. This means that even in the most dangerous circumstances, a lethal current wouldn’t pass into the trunk and heart.

However, if the voltage does exceed 50 volts, the human body can act as a conductor in a deadly way. High-voltage electricity, anything over 50 volts, can lead to burns, broken bones, hearing loss, eye injuries, cardiac arrest, and even death. Shockingly, just 10 milliamps through the human heart can disrupt its electrical conductivity, producing a fatal arrhythmia. This is why it’s common practice to limit voltage to over 50 amps.

To put it simply, battery voltage isn’t necessarily dangerous. It’s the current that’s dangerous since voltage merely measures the pressure moving electrons from one place to another. So next time, consider the pressure and learn how to best protect yourself against potential dangers.
