Why Choose a 12V Lithium Ion Battery for Off-Grid Solar?
Lithium batteries, particularly LiFePO4 (Lithium Iron Phosphate), are ideal for solar power systems due to the following advantages:
- Longer cycle life: Up to 5,000+ cycles compared to 500-1,000 for lead-acid batteries.
- Lightweight: Easier to install and transport, particularly for RV and marine users.
- High energy density: Stores more energy per pound, maximizing storage capacity.
- Deep discharge without damage: Provides 100% usable capacity without affecting performance
- Low maintenance: Requires no watering or constant checks like traditional lead-acid batteries.
