Full Feature List:
- Includes USB Monitoring & Programming Cable for customizing setpoints and extended status monitoring.
- Over Voltage Protection: If any cell(s) in your pack exceeds a safe voltage, the BMS will stop charging current from passing through, but will allow loads to draw power from the BMS without needing to be manually reset. The BMS will automatically reset when voltages fall back within a safe range allowing for charging.
- Under Voltage Protection: If any cell cells(s) in your pack fall below a safe voltage, the BMS will stop power from being removed from your battery pack, while simultaneously allowing charge current to enter to bring the cells above the minimum safe voltage.
- Over Current & Short Circuit Protection: If you accidently draw too much power from your batteries, the BMS will interrupt this current, preventing damage to your batteries.
- Under Temperature Protection: LiFePO4 batteries cannot be charged below 0° C (32° F). This BMS will disable charging when temperatures are too low, and automatically re-enable charging when temperatures are back within safe limits. Limits may be adjusted using USB Programming Cable.
- Over Temperature Protection: This BMS will completely turn off if the temperature probe(s) detect temperatures in excess of 75° C (167°F), preventing damage to batteries in high-heat applications.
