PRODUCT DESCRIPTION
Rich Solar 12V 20Ah LiFePO4 Lithium Deep Cycle Battery (256Wh)
The Rich Solar 12V 20Ah LiFePO4 Lithium Battery is a high-performance, maintenance-free deep cycle energy storage solution engineered for reliability and long service life. Built with premium Grade A+ LiFePO4 cells, this lightweight 256Wh battery delivers stable power for RVs, marine vessels, solar systems, off-grid cabins, and critical backup systems.
Key Features & Benefits
- Premium Grade A+ Stability: Manufactured with top-tier Lithium Iron Phosphate (LiFePO4) chemistry to ensure maximum thermal stability, chemical safety, and optimal discharge efficiency.
- Advanced Built-In BMS Protection: The integrated Battery Management System protects against overcharging, over-discharging, over-current, short circuits, and features low-temperature charging protection.
- Exceptional Cycle Life: Provides over 3,000 cycles at 70% Depth of Discharge (DoD), drastically outlasting traditional lead-acid alternatives.
- Expandable Power Configurations: Supports parallel scaling up to 4 units (4P) to increase total current capacity as your power needs grow.
- Ultra-Lightweight Profile: Weighing only 4.6 lbs, it offers a compact, high-energy-density alternative that reduces vehicle and kit weight.

Frequently Asked Questions (FAQs)
Q: Can I connect multiple Rich Solar 12V 20Ah batteries together to scale up my capacity?
A: Yes. You can safely expand your system by connecting up to 4 units in parallel (4P setup) to match increasing storage and current runtime needs. Connecting in series is not recommended for this model.
Q: What does the built-in Battery Management System (BMS) protect against?
A: The smart integrated BMS keeps your battery safe by preventing common causes of cell degradation, automatically cutting off power in instances of overcharging, over-discharging, excess current spikes, short circuits, and extreme high or low-temperature exposure.
Q: What are the charging temperature limitations for this lithium battery?
A: For safe operation, charge the battery when ambient temperatures are between 32°F and 131°F. Discharging can safely occur in cold temperatures from -4°F up to 140°F.
Q: Is this battery safe to use inside closed spaces like a camper, van, or indoor workshop?
A: Yes. Rich Solar LiFePO4 batteries are sealed, maintenance-free, and do not emit toxic gasses or spill liquids, making them completely safe for interior installations and off-grid workspaces.
