Electric Bike Outfitters Dolphin 48v 12.8 Ah Spare Battery w/Standard Controller and Charger

Electric Bike Outfitters Flat Style (Dolphin) Lithium-ion Battery (LG Cell) with integrated USB port.  Great battery with toughened construction.

Includes the 54.6V 2.0A charger, keys, and the battery mounting bracket system (controller with three cables) for the Electric Bike Outfitters Burly hub motor.  

To carry a second battery on your trike or bike, you may need a second battery mount (See our website for a variety of battery mounts.) or a battery pannier storage bag for a rear rack, like the Ortlieb E-Mate Pannier Bag Black.

Batteries can be swapped out when the first one runs out of juice.
