I'm wondering how much power my 36v 7ah and 60v 14ah battery packs can take after being fully charged if I don't shut the charger off without being damaged. I'm leaning towards 500ma on the 36 pack and 1a on the 60v pack. I'm designing a trickle charger and would prefer to not have to build a controller. I'm fine with slow charge (20 hours from dead to full). I spent a half hour on google and couldn't find any info. Note that both packs are exposed to open air outside (or in garage if it's raining), so heat or gas buildup shouldn't be a problem.
