Meet the 330Ah LiFePO4 Battery Pack 3.2V with BMS — a high-capacity, rechargeable cell module designed for RV solar installations, UPS systems, and demanding off-grid power needs. Built around LiFePO4 chemistry, it delivers reliable, safe energy with a long life cycle, helping you stay powered during extended outings or outages. Each pack is configured to connect to a BMS for safe charging and discharging, and can be ordered in 4/8/16/32-cell configurations to match your power requirements. With a nominal voltage of 3.2V and actual capacity ranging from 320Ah to 330Ah, you get substantial energy storage in a compact footprint (173 × 71 × 207 mm) and aluminum shell for durability. This model is CE certified and originates from Mainland China, reflecting a commitment to quality and safety for EU customers.

Benefits & Tips

  • High energy density and robust cycle life make it ideal for RV solar systems and critical UPS backups.
  • Maximum continuous discharge up to 330A supports high-demand loads, while the BMS protects against overcharge, over-discharge, and short circuits.
  • Compact 3.2V module with scalable cell counts lets you tailor capacity to your space and budget; safe handling with Aluminum shell adds to overall durability.
