SEO Meta Description
Odipie 12V 400Ah LiFePO4 battery delivers 5.12 kWh deep-cycle power, 250 A BMS, 5,000 cycles and 81.92 kWh scalability—up to 40 % lighter than lead-acid. Perfect for solar, RV, marine, telecom and off-grid seeking low-maintenance, high-density energy storage.

Features

5.12 kWh Usable Energy: One 12.8 V 400 Ah LiFePO4 block equals four 100 Ah packs in parallel, cutting wiring, cost and rack space.

250 A BMS & 500 A 5-s Pulse: Over-charge, -discharge, -current, short-circuit & high-temp (75 °C) cut-off keep cells healthy for 5,000cycles.
-1/3 the weight per kWh, easing freight and handling for bulk orders.

Grade-A EV Cells: zero memory effect, maintenance-free.

Wide Temp Window: discharge –20–60 °C, ensuring reliable operation from desert solar farms to alpine cabins.

Target Applications

  1. Solar / commercial storage
  2. RV, camper, caravan, marine & off-grid cabins
  3. Portable power carts

Note: This classic is intended for energy storage and deep cycle use only; it is not suitable for high-amperage cranking applications like starting engines or golf carts.
