The theoretical discharge current at 3C is calculated as follows:
45Ah × 3C = 135A
Parameter Value Battery Capacity 45Ah Specified Discharge Rate 3C Theoretical Discharge Current 135A Nominal Voltage 3.2V Theoretical Power at 3.2V and 135A 432W Important: The calculated 135A is not a guarantee of continuous output. Actual safe discharge current depends on the cells’ discharge ratings, BMS current limit, wiring, connectors, and thermal conditions. Confirm that every component supports the required current before use.
BMS Protection
This battery pack includes a Battery Management System (BMS). Depending on the selected model, protection functions may include:
Overcharge protection
