    No short circuit protection at load p+ p-board burnt. Do not short it. It heats up too much at 10amp charging not advisable more than this current. Discharge at 15amp is fine more than this board gets too hot. I had bought 5 of these and one is burnt like I said.

    Bought this product about one and half months back, and installed it about three weeks back. Looks like this is not having short circuit protection, charged my battery bank once with this BMS and kept it aside for two weeks. When I tried to check the bank, I noticed that one of track is burnt and cut.

    I think this BMS is not having proper short circuit protection because of some unknown short circuit excess current flow though the BMS and it could cause the track to get burnt.

    I feel it would be good go for BMS with good protection.
