The guide is tailored for international buyers and importers.

Table of Contents

LiFePO4 batteries are renowned for being one of the safest battery types globally, as they eliminate the safety risks associated with high-temperature runaway during abnormal battery conditions. This article serves as a concise guide on how to handle LiFePO4 batteries effectively.

One remarkable quality of LiFePO4 batteries is their energy density ratio. Compared to typical lead-acid batteries, which have an energy density ratio of approximately 40Wh/kg of lead, Seastar LiFePO4 cells provide over 150Wh/kg of lithium. As a result, higher-capacity LiFePO4 batteries are considerably lighter than their lead-acid counterparts. Leveraging the high energy density of lithium, manufacturers can further reduce cell sizes to cater to various lightweight applications.

Charging Information

Using the Seastar 12V 100Ah LiFePO4 battery as an example, it is generally recommended to use a battery charger specifically designed for lithium iron phosphate (LiFePO4) batteries. To achieve a full charge, the DC charging voltage should be set between 14.2V and 14.6V, with a charging current below 100A.

 

Here is a list of voltage levels that a LiFePO4 battery will reach different charging stages (based on a 12V 100Ah LiFePO4 battery):

LiFePO4 Cell Voltages

 

Nominal cell voltage: 12.8V
Peak cell voltage: 14.6V
Over-charge voltage: 15V
Discharge voltage: 8.8V

Charging a LiFePO4 battery involves two steps to raise the state of charge (SOC) level to 100%. The first step is constant current charging, where a constant current is applied to the LiFePO4 battery. The voltage level gradually increases until it reaches 14.6V. Until this stage, the charger maintains a constant current during the charging process. However, once the voltage reaches 14.6V, the charger locks in on this voltage and maintains it steadily. At this stage, the SOC level of the battery is approximately 90%. Subsequently, the charger outputs a decreasing current into the battery while keeping the voltage constant at 14.6V. When the SOC level reaches 100%, the charger automatically disconnects and ceases to charge the battery.

Full Battery Protection

Occasional over-discharge can occur in lithium batteries. The minimum voltage at which a LiFePO4 battery can be discharged is 8.8V. Seastar Time LiFePO4 batteries are equipped with a built-in Battery Management System (BMS) that provides protection against overcharge, over-discharge, overcurrent, and short circuits, ensuring an excellent self-discharge rate. Without BMS protection, discharging the battery even slightly below this voltage renders the entire battery unusable, with no possibility of recovery. Discharging the battery below 8.8V would result in permanent damage.

Therefore, it is crucial to discontinue using the battery before it reaches this threshold. This necessitates connecting a BMS board in series with the battery’s internal circuitry to safeguard against over-discharge.

Effects of Temperature

The temperature has a significant impact on battery performance. Lower temperatures result in reduced available capacity, and LiFePO4 batteries cannot be charged below 0 degrees Celsius.

Long-term Storage

Temperature: LiFePO4 batteries can be operated within a temperature range of -20°C to 60°C, with an ideal storage temperature between 10°C to 35°C. It is advisable to store the batteries in fireproof containers and keep them out of reach of children.

Capacity: For extended battery life, it is recommended to store the battery at a 50% charge level and recharge it every three months if it will not be used for an extended period.

These key points provide essential information for international buyers and importers when using LiFePO4 batteries. As mentioned earlier, LiFePO4 batteries offer numerous advantages over lead-acid batteries. However, it is essential to provide a suitable operating environment for LiFePO4 batteries to fully benefit from their advantages.

In this article, we will delve into the key aspects of true deep-cycle batteries, including their uses, differences from car batteries, discharge levels, and the exceptional features of Seastar batteries. This information is aimed at international buyers and importers seeking reliable battery solutions.

Table of Contents

Defining True Deep-Cycle Batteries:

A true deep-cycle battery is designed to endure constant discharge until it reaches the manufacturer’s recommended maximum depth of discharge. It can then be recharged and subjected to the discharge-recharge cycle repeatedly. Unlike car batteries, deep-cycle batteries are built to withstand such demanding applications, ensuring longevity and performance.

Wide Range of Applications:

Deep-cycle batteries play a crucial role in various industries and recreational activities. From powering golf carts and RVs to supporting heavy-duty equipment like forklifts and UPS systems, deep-cycle batteries are integral to keeping the world functioning smoothly. Their versatile applications make them indispensable in today’s multi-billion-dollar battery industry.

Composition and Plate Design:

Differentiating deep-cycle batteries from automotive batteries lies in the composition of their individual plates. Automotive batteries use sponge lead, a material with a high surface area optimized for quick energy flow during engine cranking. However, sponge lead is prone to rapid sulfation and lacks durability.

In contrast, most deep-cycle batteries feature flat plates or cylindrical tubes with sufficient active material thickness. These plates undergo a critical curing process to ensure they neither become brittle nor mushy. Seastar Battery takes pride in its 10-day curing period for plates, surpassing the industry standard of 1-3 days. This meticulous approach enhances the longevity and resilience of the batteries.

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.

Lithium-ion batteries can be fast-charged to 100% capacity without requiring an absorption phase, unlike lead-acid batteries. With a sufficiently powerful charger, it is possible to fully charge a lithium-ion battery in as little as 30 minutes. Additionally, failure to regularly fully charge lithium-ion batteries does not lead to battery damage, providing greater flexibility in energy harvesting.

High Charging Efficiency

Lithium-ion batteries exhibit nearly 100% charging efficiency, outperforming the 85% efficiency of most lead-acid batteries. This high efficiency is particularly advantageous when charging via solar power, maximizing the utilization of every amp before sunset or cloud cover.

Climate Resistance

Lithium-ion batteries excel in harsh environments, maintaining their efficiency in both extreme hot and cold temperatures. In freezing conditions, lithium-ion batteries outperform lead-acid batteries significantly, delivering more than 80% of their energy at -20°C, while AGM lead-acid batteries provide only 30% of their capacity. For applications exposed to challenging climates, lithium-ion technology proves to be the ideal choice.

Fewer Placement Issues

Unlike lead-acid batteries, lithium-ion batteries do not require upright storage or vented battery compartments. Their flexible assembly capabilities enable easy integration into various shapes and configurations, making them ideal for maximizing power capacity within constrained spaces.

Zero Maintenance Requirements

Lithium-ion batteries are virtually maintenance-free. The built-in Battery Management System (BMS) ensures automatic cell balancing, eliminating the need for manual maintenance. Simply charge the battery, and it is ready to power your applications reliably.

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.
