The BMS will automatically reset when the high current condition is corrected. If the high current condition is not resolved or becomes too high, the BMS will completely disconnect the circuit. Current Limiting Protection: The BMS will limit the charge and discharge current to protect the cells. We recommend active power management using a battery monitoring system (coulomb counter) like the Expion360 model to prevent this from occurring. Some charge sources will not charge when they detect an open circuit as they will when the BMS has disconnected it.

If this occurs, to reset the BMS, add a charge source to the battery or connect to another battery as if jump starting. Over-Discharge Protection: The BMS will disconnect the circuit when the battery reaches its minimum voltage to protect the cells. When the condition is corrected, the BMS will automatically reset. If the high voltage condition has not been resolved or gets too high, the BMS may completely disconnect the circuit. Over Charge Protection: The BMS will limit the charge voltage to protect the cells. When the short circuit condition is corrected, the BMS will automatically reset. Short Circuit Protection: If a short circuit occurs, the BMS will disconnect the circuit to protect the cells. Cell Balancing: The BMS's primary function is to provide even charging and discharging of the individual LFP cells within the internal battery pack. BATTERY MANAGEMENT SYSTEM (BMS) See the technical specification page for BMS disconnect settings. The oversized power terminals provide a unique electrical and physical connection point for higher gauge power cables and our unique parallel bus bars. The unique and proprietary case contains structural elements to protect the battery pack and battery management system (BMS) inside from the effects of vibration and movement. The power distribution plates connecting the cells, BMS, and internal terminals are solid machined copper. All internal power distribution cables are mechanically connected (bolted) rather than soldered to promote efficient power delivery with less resistance while providing a robust physical connection point. The cells are UL 1642 listed, meeting the highest standard in safety and performance. The VPR uses cylindrical sized stainless steel encased LFP cells. LFP is considered the best choice for this application because of its high degree of safety, long service life, and excellent dependability. It uses Lithium Iron Phosphate (LiFePO4/LFP) as its battery chemistry.
