I am trying to find a good charger that plugs into outlet AC and charges a 4x 4s 14.8v pack for my ebike but I cant seem to find any just standard 60v or 72v chargers that are commonly used for charging SLA. Would those still work for charging a 60v lipo pack that goes to say 67.8v when fully charged? I have multimeters to keep track of the voltage too so incase if it is overcharging i can stop it. I prefer using ebay, try and avoid amazon as I hate purchasing amazon items cause their new policy and shit.
