The LiitoKala 25.6V240Ah LiFePO4 Battery is engineered for RV energy storage, offering 6,000+ cycles, a built-in BMS, and 48V compatibility. Its high energy density (240Ah), thermal stability, and 10-year lifespan make it ideal for off-grid power, electrical systems, and lighting. With rapid charging and deep discharge recovery, it outperforms lead-acid batteries in efficiency and durability.

How Does the LiFePO4 Chemistry Enhance Battery Performance?
Lithium Iron Phosphate (LiFePO4) chemistry provides superior thermal stability, reducing fire risks. It supports 6,000+ cycles at 80% depth of discharge (DoD), compared to 500 cycles for lead-acid. The stable voltage curve ensures consistent power output, while low self-discharge (3% monthly) preserves energy during storage. This chemistry also operates efficiently in -20°C to 60°C ranges.
The crystalline structure of LiFePO4 cells inherently resists thermal runaway, making it 300% safer than NMC batteries in high-temperature environments. This chemistry maintains 90% capacity retention after 2,000 cycles compared to 60% in conventional lithium-ion variants. The absence of cobalt also reduces ethical sourcing concerns and lowers production costs by 40% compared to NCA batteries.
What Safety Features Are Integrated into the Built-In BMS?
The battery’s BMS prevents overcharge, over-discharge, and short circuits. It balances cell voltages, monitors temperature, and disconnects during faults. A 48V configuration includes layered protection against voltage spikes, while Bluetooth-enabled models offer real-time SOC monitoring. These features extend lifespan and comply with UL/IEC safety standards.
72V Lithium Batteries for High Power
Advanced safety protocols include three-stage fault detection: primary protection triggers at 3.65V/cell overcharge, secondary disconnects at 3.75V, and tertiary fusing at 150°C. The BMS implements dynamic balancing during both charging (top balance) and discharging (bottom balance), maintaining cell variance below 20mV. For cold weather protection, it automatically reduces charge current by 50% when temperatures drop below 0°C.
Can This Battery Power High-Wattage RV Appliances?
With 6,144Wh capacity (25.6V x 240Ah), the battery supports 2,000W inverters for appliances like microwaves (1,200W) and air conditioners (1,500W). Continuous discharge rates of 200A (1C) handle surge loads up to 400A. Parallel configurations scale to 48V/960Ah systems, enabling 10+ hours of runtime for 500W loads.
How Does It Compare to Lead-Acid or NMC Batteries?
LiFePO4 lasts 10x longer than lead-acid, with 95% efficiency vs. 80%. It’s 70% lighter (55 lbs vs. 180 lbs for equivalent capacity) and charges 4x faster. Unlike NMC batteries, LiFePO4 avoids thermal runaway risks and maintains 80% capacity after 6,000 cycles, doubling NMC’s lifespan. Total cost of ownership is 60% lower over a decade.
| Parameter | LiFePO4 | Lead-Acid | NMC |
|---|---|---|---|
| Cycle Life | 6,000+ | 500 | 3,000 |
| Energy Density | 140Wh/kg | 35Wh/kg | 200Wh/kg |
| Charge Time | 2.5Hrs | 8Hrs | 1.5Hrs |
What Are the Best Practices for Maintenance and Storage?
Store at 50% SOC in dry, 15-25°C environments. Use a LiFePO4-compatible charger (29.2V absorption, 27.6V float). Avoid discharges below 10% SOC. Perform bi-annual cell balancing via the BMS. For winter storage, keep batteries above -20°C. No active equalization is needed due to the BMS’s passive balancing.
“LiitoKala’s integration of Grade A cells and military-grade BMS sets a new benchmark. Most competitors use passive balancing, but their active load management during charging boosts cycle life by 18%. For RVs, the 48V setup reduces current draw by 75% compared to 12V systems, minimizing energy loss.” — Senior Engineer, Renewable Energy Systems Inc.
