This battery pack weighs just under 7 Kg (15 lbs) and takes about 2/3 of the room in the frame bag providing ample space to hide a small to mid-size controller and wires to make your e-bike build look clean. In-frame placement of the battery allows for the best weight distribution enhancing handling and safety of your e-bike. 

This battery is one of the most powerful in its class, yet much safer and easier to use than LiPo packs. It is capable to output 60A continuously or 120A in bursts without overheating. It’s ideal for high torque 3-5 kW motors. 

The battery is made of the high-quality Panasonic cells, best available today, that will outlast any generic cells. The pack is sized to minimize stress on individual cells and prolong the life of the pack even more. This pack is estimated to run at least 30,000 miles. 

The battery fits most bike frames sizes 17'' and up.
