Got my NEW Headway BMS - It's finally all working!

Hi dnmum,

Which small wire you are talking about?
In my BMS there are 2 yellow wires in P-, there are no C-.
So i I should share charging with P-?

you need to post up a picture, don't follow his advice and charge through the negative leads because that will eliminate the BMS's ability to stop the charge. you need to connect the negative charging lead to the source leg of the charging FET.

All these Headway/Ecitypower/BMSBattery type BMS units seem to have them same connection. This was emailed to me when I asked the company how to hook it up. Different design but same connections as yours:

Where can this 72v BMS be purchased? Are there any other brands to consider?

Hi guys. Has anyone nutted out a schematic for any of the Headways BMSs. I have 12 of them in a car (each is 16 cell) and would love to have a better idea of what works where.
