I have this problem. I just added another 12v sla battery for a total of 4 ( for 48v) but only have the 36v charger - so I thought i'd charge up 3 of them as a pack, then drop one fully charged battery- Then add the remaining battery and charge that combo to 36 V - This should assure all batteries had a level 12v charge across the board to equal 36v right? ( the bateries are wired in series) - and thus I would have my 48 volts because all batteries were charged.
Well when I add that last battery to the other 2 fully charged batteries it only takes 2 minutes to charge to 36v. As a pack charging 3 at a time takes anywhere from 45 minutes to an hour and a half. I know it depends on how much i drain the pack but 2 minutes to top off the last battery to 12 volts? That seems really fast to me so i am thinking there is something wrong. I do not have a 12 meter to test the battery.
Any thoughts?
