Maybe the thread name should be edited to " Zephyr BMS - Good Idea but Boards Are Not Available". The current title tends to imply that "finally" something is available when it isn't.
You can PM me. You would need to measure some points on the board to figure out what might be going on. I assume by 'bypass' you mean install the EOC disable jumper.chxs said:i have BMS v4.4 and i get problems with ... i can't get the fet activating by itself ... if i bypass it the charge cycle is fine and the led switch from orange to red at hvc ... but if i don't bypass the fets the charger don't detect anything !but i can read the voltage at the pole of charger and all cells is shunting well ... !! what is the problems .... what i have to check ??? tank you very much !!
fechter said:I hope to get a run of boards done at some point. I need to revise and check the most recent version very carefully before submitting a run, as mistakes are too costly. Once the layout is 'validated' with a successful test, a larger batch could be done. Right now, time availability is more of a limiting factor than money.
