Check compatibility before ordering

This is not a universal drop-in replacement. Before purchasing, verify all of the following:

• Your e-bike/controller uses a 48V battery system.
• Controller rated current does not exceed the battery's 25A continuous-discharge rating.
• The frame has enough clearance for the battery and for sliding it on and off the base.
• The mounting-hole positions, DC5521 charging port, 5-pin base connection and XT60 wiring are compatible.
• Red and black wire polarity is verified by a qualified installer before connection.

Installation note: Professional installation is recommended. Do not short-circuit, puncture, crush, modify or expose the battery to water, fire or extreme heat. Use only a compatible 54.6V lithium-ion charger.
