Is the 48V 20Ah KT-E12 Compatible with My Electric Motorcycle?

Compatibility depends on five points. Check each one against your vehicle:

Controller voltage and current limits (the pack's maximum discharge is 30 A)
Motor power
Charger output (54.6 V limit, 3 A standard charge current)
Battery compartment size and mounting arrangement
Charge and discharge connector arrangement

We do not publish model-by-model vehicle compatibility or controller protocols for this pack. Instead, we check each project against your drawings before quotation. Please send the vehicle model, controller and motor data, charger specifications, compartment dimensions and connector photos.

Quality Control and Documentation

The KT-E12 is built to approved specification 12.095.080 (Rev A0) and its drawing. Tell us which inspection records and test reports your project needs, and we will confirm what is available for your order.

Applications

The KT-E12 suits electric motorcycle and e-moped platforms that work on a 48 V system with a controller limit of up to 30 A. At 30 A maximum discharge (about 1.4 kW at 48 V), it is aimed at light-duty platforms rather than high-power motorcycles.

Typical projects include urban commuter bikes, delivery vehicles and fleet or rental models. Duty cycle and range targets are reviewed for each project.
