Parallel module

You know when connect in parallel, if packs have big voltage difference , it will cause huge current right ? So to avoid the high current damage the battery , we will use the parallel module to limit this current,
The parallel module turn on logic is :
when one pack trigger overcharge current level 2 protection, the high voltage pack BMS will turn off charge MOSFET,, discharge through parallel module to the low voltage pack .
If you use 15A parallel module, then when parallel logic working, only can allow 15A current flow from high voltage pack to low voltage pack.
