36v Ebike Batteries are popular batteries in low power production ebikes and make good replacements for these systems. All our 36v ebike batteries are made up of name brand 18650 cells and charge to maximum of 42 volts. Low voltage cut off is at 32 volts. If your ebike has a 36v battery (your charger will charge to a maximum of 42 volts) our 36 volt batteries will make a great back up battery or additional battery to use on your system. 36v Ebike Batteries do not put out as much power as the other batteries we carry, but are popular in the low power segment.
