You can charge your battery by using the included 48V 2 Amp charger. The charger is rated for both 110V and 220V AC power outlets, so you don't have to worry about adapters.
Our bike batteries can be charged on or off the bike; you can leave the battery locked to the frame when charging or you can remove the battery from the frame using the included keys and charge the battery on its own!
You can charge your battery after each and every use, even after taking a short ride. The battery has no memory effect (unlike other battery chemistry), is completely self-managing, and the charger stops automatically when the battery is fully charged.
You should store and charge your batteries in dry locations indoors, and away from direct sunlight, dirt or debris, and metal objects. Always charge the battery in temperatures between 50-80 degrees Fahrenheit and ensure the battery and charger are not damaged before initiating a charge.
The lights on your battery charger will show two red lights when the battery is charging and one red/one green light when the battery is fully charged.
If you notice anything unusual while charging please discontinue charging and use of the bike and contact Rad Power Bikes for help.
Please refer to your Owner's manual for more information on batteries and charging.
