    Hi, I have just purchased this electric bike

    wheel, and I have connected 3 12 volt Sealed Lead Acid batteries in series making a 36 volt battery that the bike requires. It seems as though the batteries are low (but it is wierd as they read 38 volts on my multimeter.) Anyway, I bought this charger for the batteries

    I realize that it says lithium battery charger, can I use this charger for the batteries? Does anyone know what type of charger I need? I am by no means knowledgeable about this stuff, so I could use as much help as possible, thanks!

    Battery that you have ate probably week, they lack the amperage. Batteries are rated wih volts ampers, and amp hours

    For that bike you need 20a total amperage, for full power

    You cant charge acid with lithium battery charger

    Return that Li-on energtizer. Purchase an energizer specifically made for the particular sealed lead acid (SLA) battery you have. Google for SLA batteries, and you will receive more hits than you can read in your lifetime.
