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 229g, the 4-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.

Sealed within its hard-case shell, the circuitry and cells are protected from the harsh elements. The 2-cell Battery Pack is 100% protected from water ingress and is completely waterproof. Rain or shine, this battery will give you the power you need. We know your helmet is crash-proof. That's why our hard-shell batteries are able to withstand hard-hitting high impact crashes too. Drop them 20m off the ground, it'll be the last thing to break on you. Use the velcro strap to attach your battery to your frame, handlebars or helmet.
