Joe, what is the total pack voltage? If the packs are nearly fully charged, you will get a low tapering charge rate although I don't know why it would take so long unless the cells were way out of balance.
Currently 38.5V.
I don't even know what the voltage range is for these packs. Probably need to figure that out[&o] I thought it should go up to 42V or something.
