Say goodbye to bottle cage batteries: Long gone are the NiMH water bottle cage batteries. Since the arrival of new LED bike lights, we've been blessed with lightweight, powerful lithium ion cells. Weighing only 410g, the 8-cell Battery Pack is both lean and mean. Top-tier Samsung lithium ion cells ensure maximum power and defining leading-edge capacity so you can go harder for longer.
All-weatherproof: Wrapped and sealed within a protective outer layer, the battery cells are shielded from the harsh elements. The 8-cell Battery Pack is cushioned with layers of foam padding in its exterior soft-case pouch. Use the velcro strap pouch to attach your battery to your frame or handlebars.
