Hello,
I am building a bank of SLA batteries totaling 48V, four 7 amp batteries wired in series for my EBikeKit hub motor. I don't like the taste of paying $25+ for a 48V charger, and I already have multiple 12V smart chargers for car batteries that can charge at up to 8 amps. Would charging the batteries in parallel hurt them? At 8 amps, each battery would charge at 2 amps which the spec sheet states to be within charging range, and It would equalize the batteries aswell, wouldn't it? I can't see how it could be disadvantageous (All batteries are within .3 volts of each other sitting, same date codes) but I have been advised in the past not to do so with NiMh batteries.
Thanks,
Brandon
