The nominal voltage of the 14-string battery pack is 3.6V*14=50.4V, and the current is 1000W/50.4V=19.84A (excluding loss and conversion rate). As the voltage increases, the current will decrease.
[pdf] This section explains how to repair a lithium battery pack by addressing the most common issues: faulty cells, BMS errors, swelling, and short circuits. You will also learn when to attempt repairs yourself and when to consult a professional.
[pdf] A lithium battery pack is an integrated battery system. It is built by connecting many individual cells in series and parallel. It includes a Battery Management System (BMS), reliable electrical connections, and a protective structural package.
