Frequently Asked Questions
Q: What battery chemistries is this BMS Protection Module compatible with?
A: This BMS module is specifically designed for LiFePO4 (Lithium Iron Phosphate) battery cells in a 4S configuration. It is optimized for the voltage and charge characteristics of LiFePO4 chemistry and supports up to 24S series connections for high-voltage applications.
Q: What current rating should I choose for my build?
A: Select a current rating that matches or slightly exceeds your system's expected peak discharge and charge current. Available options are 40A, 50A, 60A, 100A, 150A, and 200A. For example, if your system draws up to 80A peak, choose the 100A variant for a safety margin.
Q: Does this BMS protect against short circuits and overcharging?
A: Yes. The module includes integrated protection against overcharging, over-discharging, overcurrent, and short circuits. It also features temperature monitoring to help prevent overheating, making it suitable for demanding energy storage and power delivery applications.
Q: Are batteries or a charger included with this module?
A: No. This listing includes only the 4S LiFePO4 BMS Protection Board. Batteries and chargers are sold separately.
