this is a fallacy - the unregulated out of control alternator scenario, like an out of control nuclear chain reaction. Disconnect the bms and things revert to a charging system used for decades, the alternator still contains a built in rectifier and voltage regulator(maybe done by the ecu). I've had the bms disconnected for over a year and battery works fine. There are certain situations like very hot climates I'd advise against this as a precaution, but otherwise it works, the bms is not voodoo or black magic, just a modification of voltage regulation/charging tied primarily to support the ass function. As you can see by my avatar I live life on the edge but when I initially disconnected the bms I dressed for any possible outcome, but in the end the only one I've experienced is a healthy battery. If you or others wish to contract me to perform a bms disconnect it can be done for $2k plus expenses. Or rate can be reduced if it's done as a group of 5 or more with close geographic proximity, schedule is filling up quickly though as I also perform damper removal services.Sounding like a "what oil do you recommend" thread now. Is @AzScorpion getting commission on ctek chargers?
At the risk of going in another direction, after reading about the function of the bms, I'm curious what disconnecting the bms does. My thought is you are running an unregulated charge to the battery which will end up shortening the battery life. Or is there a failsafe that limits the max charging voltage?
@airline tech, wondering if that scenario has been tested.
