I purchased a 5A 12v CC CV charger to power the 3s BMS charger. 5a CC CV charger https://www.ebay.com/itm/292316891852 3S BMS https://www.ebay.com/itm/3S-10A-12V...pid=23015876544&hash=item2cdfb0c45c:rk:1:pf:0 Here is how I hooked it up https://photos.app.goo.gl/1Xp24GhYFC1ziB1W9 https://photos.app.goo.gl/HKdX4XxgqpyUf2Kw9 https://photos.app.goo.gl/kDw3YbpsAeqy26Ar8 https://photos.app.goo.gl/kemRaGknDQqTtPox6 I hooked up the BMS first testing the voltage at each point and then on the output and saw 11.8v output as I expected. Then I hooked the 2 outputs from the BMS to the output of the charger. Then strangely the large black thing that looks like a transistor or something bubbled up and smoked. No input was hooked up only the batteries to the output. The green light comes on on the charger even though nothing is hooked up to the input. But when I hook up a power source to the charger no power ever comes out the output. No amperage. Not sure how I hooked this up wrong from the beginning. Any thoughts? What did I do wrong?
