So I’m hooking up my Bestech BMS and am having an issue getting any output at all I’m a little worried I may have shorted something. I have B1-10 (10S pack) connect properly as far as I can tell. I have the first P group (negative) soldered to B- and can’t get a reading from P-. I probe the negitive lead and each B group sequentially and get the expected incremental voltage.
I’ve also connected the built in e-switch.
When I first connected everything I had a reading from P- with the expected voltage WITHOUT connecting the e-switch. Which I thought was odd. Anything else I could try?
I’m worried I shorted it because when checking the incremental voltage under the BMS I accidentally bridged two of the B group connections and here I tiny spark. Could that have been the fatal blow?
