  1. Please ensure the correctness of the wiring sequence, from B0-B12, B13-B24, the voltage increases from low to high in sequence.
  2. This BMS is compatible with battery packs up to 24s, which is over 100V DC when fully charged. Electric shocks from high voltage may cause serious injury. Please pay attention to safety when using.
  3. This device is designed to reduce the risk of charging and will not protect against overcurrent discharge, undervoltage, internal pack shorts, pack overtemperature.

BMS starts working after connecting the thermal protection switch. When connecting the BMS to the battery pack, connect the 13 pin B0–B13 connector to the BMS before connecting the 12 pin B13–B24 connector. For battery packs under 24S, the additional balance wire should be removed from the GH2.0 connectors. For example, and 18s battery will have balance connections from B0-B18, and B19–B24 disconnected. 15s batteries will have connections from B0-B15 and B16–B24 disconnected.
