Built-in BMS protection includes overcharge protection, over-discharge protection, charge overcurrent protection, discharge overcurrent protection, and short circuit protection.
Thermal protection from the BMS includes discharge high temperature cut-off and charge high temperature cut-off, preventing operation outside safe limits.
Charging temperature range is from -10°C to 50°C, allowing use in cold and moderately hot environments, though best results are achieved between 10°C and 35°C.
Discharging temperature range extends from -15°C to 50°C, supporting operation in colder conditions than charging.
Operating ambient temperature is specified from -20°C to 50°C, with recommended storage between 10°C and 35°C and humidity below 70%.
Series connection capability: up to four identical 12.8V 100Ah batteries can be connected in series to form a 48V (51.2V nominal) battery system.
Parallel connection capability: up to four identical batteries can be connected in parallel, increasing total capacity to 400Ah while maintaining 12.8V.
Maximum system expansion supports connection of up to 16 identical batteries in various series/parallel combinations (e.g., 4S4P).
Recommended charging method for full capacity: charge at 0.2C (20A) for about 5 hours to reach 100% state of charge, or at 0.5C (50A) for about 2 hours to reach approximately 97% capacity.
Battery cell type used in the 100Ah model is 38121-15000mAh LiFePO₄ cells, with Grade-A construction and no Bluetooth function on this model.
