【First Use & Charging Notice】 1.To protect battery health, some units may ship in 0V protection mode. Use a 14.6V LiFePO₄ activation charger to wake it up before charging (e.g., 14.6V 8A charger with 0V function). 2.Avoid using 12V chargers, standard lead-acid chargers, or automotive chargers. Chargers with repair, pulse, or desulfation modes designed for lead-acid batteries may interfere with the LiFePO₄ BMS and trigger early protection shutdown.
3.Before connecting batteries in series, ensure each battery is fully charged and the voltage difference does not exceed 0.2V (fully charged ≥14V). 4.To maintain battery health, charge at least once every 2–3 months if not in use. 5.When connecting multiple batteries, use the same model and age; for best balance, fully charge each battery individually before series connection. ✅ Using a LiFePO₄-compatible charger helps extend battery life and ensures reliable, safe performance.
