FAQ



  • Yes. This battery supports up to 2 in series (2S for 48V systems) or up to 2 in parallel (2P) to expand total capacity to 200Ah (theoretical maximum). For 2S2P configurations, a total of 4 batteries can be used to build scalable energy storage systems.

    For best performance and safety, please use batteries of the same model, capacity, 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 24V 100Ah LiFePO4 battery delivers 6,000+ cycles at 80% DOD, depending on usage and conditions. This translates to a service life far longer than traditional lead-acid batteries.

  • With a dedicated 50A 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.
