Thank you so much Jim! That will help a lot
with my swingarm build. And I didn't realize the old ICE motor was mounted to the swingarm, that is wild.
As for the BMS going to sleep... that is strange but not unheard of. I bought a very small 10amp BMS for a 12v pack, and when I wired it to the batteries, it was asleep like you described. Had to plug it into the charger to turn it on. Then it went to back to sleep about 12 hours later. I gave it a good charge and now it stays on until the battery is drained to the minimum voltage, like it should.
So what I'm saying is: hopefully the BMS stays awake after it's been charged a few times...??? Otherwise I don't know, might have to replace it.
Hopefully somebody else can chime in with more knowledge than me because I too have a DALY bms and I wasn't aware of this problem with them.
