TOP EV-GRADE LiFePO4 CELLS

Built with premium EV-grade LiFePO4 cells, this battery delivers exceptional safety, stability, and longevity. Rated for 4000+ cycles at 100% DOD, it provides reliable power for RVs, marine electronics, off-grid systems, and outdoor adventures.

Low-Temp Protection for Long-Term Reliability

The battery automatically stops charging below 32°F (0°C) and discharging below -4°F (-20°C), then safely resumes charging at 41°F (5°C)—helping protect the battery and extend cycle life.

Lighter, Stronger, More Durable

At only 51.35 lbs, this battery is 20% lighter than a comparable lead-acid battery while delivering 2560Wh of usable energy. With a 10-year lifespan and 4000+ cycles, it provides longer-lasting power with less weight and maintenance.

Powerful 100A Smart BMS Protection

Our self-developed 100A Smart BMS supports up to 100A continuous charge/discharge current and features 20+ advanced protections against overcharge, over-discharge, overcurrent, short circuits, and extreme temperatures—ensuring safe, stable, and reliable power for every journey.

FAQ



  • Yes. Our 12V 200Ah LiFePO4 batteries support up to 4 in series (4S) to build 24V, 36V, or 48V systems, or 4 in parallel (4P) to expand capacity up to 800Ah. For best results, always use batteries of the same model, age, and state of charge.

  • Yes, it is compatible with solar charging systems for home backup, RV, van life, camping, and off-grid energy storage.

  • Yes. The battery has an IP65 waterproof rating and a built-in 100A BMS that protects against overcharge, over-discharge, overcurrent, short circuit, and extreme temperatures. It’s reliable for marine, RV, solar storage, and off-grid use.

  • The 12V 200Ah LiFePO4 battery delivers 4,000+ cycles at 100% DOD, depending on usage and conditions. This translates to a service life far longer than traditional lead-acid batteries.

  • With a dedicated 100A fast charger, this battery can be fully charged in approximately 2 hours (from 0% to 100% at room temperature). Actual time may vary slightly based on initial charge level and ambient conditions.

  • Store the battery at 30%-50% charge in a cool, dry place. We recommend charging it every 6 months when not in use to prevent over-discharge and maintain optimal performance.
