I have a couple of the el-cheapo-ebay-china BMS's that are design goal wise set to 4.2 for the balance voltages. I like to run my packs at a max of 4.1 V/cell to promote pack health. So maybe I can change it to 4.1 ? Maybe a bunch of resistor changes or something ? I'm just shooting in the dark. I do have one of the programmable 'ANT' type BMS also, but I'd like to get some use out of the more compact and cheaper 'dumb' BMS's as well. Side question : Why do they all seem to use 4.2 as max voltage ? Great way to shorten a packs life. Imagine if EV cars did something so dumb, always charge to the max cell rating.
