The PCM circuit of the LFP batteries cannot replace proper fusing

Recently there were several cases of customers who damaged the LFP batteries with the PCM by over current or short-circuit.  As any batteries, the batteries with the PCM protective board need to be fused by a proper size fuse. In case of an accidental short-circuit connection, the fuse will protect the battery against high current that can cause the damage the PCM board and the whole battery.

The photo shows one instance of improper use of the LFP battery with the PCM. The two places on the battery connector plus pole prove the repeated over-current that even melted the connector.

The damage by over-current is not covered by manufacture warranty and there is no way to repair a battery that was damaged this way.
