Hailong 36/48/52V | Rebuild Service

Ebike Battery Rebuild

The Hailong case is one of the most popular e-bike batteries worldwide — sleek, downtube-mounted, and reliable. But when the cells inside lose capacity, your rides get shorter and less powerful. Our rebuild service restores your Hailong pack with new Grade A lithium cells and a tested or replaced BMS, bringing your e-bike back to full performance.
