Hello fine feathered friends, and tarred friends. And you,
I've got this issue see... Instead of running my electric Kaishan e-scooter on the regular 48 volt SLA battery pack, I'm running it on that and a fifth 12 volt SLA battery to make it a 60 volt system. I've made sure that all the batteries are the same capacity via a CBAII battery load tester, within about 0.8 Amp-hours... But the thing that troubles me is that the all-important fifth battery is under the seat of the bike, whereas the 48 volt battery pack is in the floor of the bike. All told there are about three feet of wire and two connecting Anderson clips between the 48 volt pack and the fifth battery. In theory, could this extra length of wire between two of the batteries cause them to become un-balanced when they are charged or discharged? And yes - I'll actually be using a 60 volt charger this time round, rather than the 48 volt and 12 volt chargers I'd tried to use before.
I swear if this doesn't work I'll move to a Mr. Fusion or something. And stuff.
