A2B Metro BMS Replacement options

Post by adh247 » Nov 05 2020 5:59am

Hi guys!
I have an A2b Metro and thought I would seek advice.

If The Batteries in the frame aka "A" Battery are in perfectly good working order, but the BMS is not, where would I go to find a working BMS?

Would Something like this work for me?

Not sure if a2b parts are available in other parts of the world but here (aus) they are long gone.
Full functionality requires the proprietary bms. I think the system still works with a simple bms with a 2 wire output (pos + neg only) but you loose battery charge level indicator on the display. I could be wrong on this as I haven't done it myself, just seen others doing it.
