Looking for a dead Ezee 36v Li Ion battery
Hi there - a Newbie to the forum here.
I've got an Ezee electric bike, powered by a 36V 14Ah Li Ion battery.
It was great, then the battery just stopped working at all, then it started working again, then it stopped, and I took the battery to bits.
I used my LiPo balance charger (for models) to do a balanced charge & discharge & the cells are fine - they have plenty of power.
BUT as soon as I try and draw any juice from the whole pack, the voltage drops from 42V to zero.
I'm 95% sure that the BMS (Battery Management System) is to blame. I can't find any dry joints / loose wiring, so....
Does anyone have an old dead Ezee battery from which I can steal the BMS?
Or do you know where I can get a replacement?
I'm fine with a soldering iron, so I'm happy swapping it over.
I'm also VERY aware that I've got 0.5KwH of power & that needs to be treated with extreme caution.
Thanks,
James
