So today i was testing my Chargery BMS. all the readouts seem to be working fine. I had 1 relay connected to the low voltage shut off side of the BMS output. And it was working as expected.
However low voltage shut off is not necessarily a problem for me right now but overvoltage is. So i decided yo move the relay from the low voltage side to the high voltage side. The first thing I did was disconnect the battery from the SCC when I did this the Chargery instantly turned off and started heating up. I mean too hot to touch and I think it may be blown.
Anybody have any ideas what happened. What I did should of been no different than what the chargery does when it shuts off charging.
