I have got a modified bike with a front wheel running on 36v sla agm batteries. 3 x 12v.
I used the charger that came with it and one time I forgot it.. it over charged. batteries expanded and I think I got hydrogen. they were very hot.
I was very scared. I replaced Bart's with news ones. got a 36v soneil charger.
I put a voltimetre on the 36v terminals when its charging. I read 43.3.. still charging. isn't that a high voltage when a full 12v charge is about 12.8v?
also. when I measured across each of the batteries while they are charging using the 36v 2a soneil. I got 14.79 14.23 14.14..
why each battle has a different voltage..
I if anyone can explain any of this... please do..
thanks a lot.. :-)
