Silva 2.4Ah Soft Battery

Velcro soft case that can be attached to the neck plate, belt or bike frame
Withstands heavy rain and water from any direction

A lightweight rechargeable battery (2.4Ah). This water-resistant battery pack comes in a multi-attachment Velcro soft case that can be attached to the neck plate, belt or bike frame. The battery meets IPX5 standard: Water resistant; withstands heavy rain and water from any direction. The LED battery indicator ensures that you can keep track of how much power that remains in the battery while charging. The battery is easily charged via a micro USB cable and has a charging time of 4 hours.

Our battery line-up gives you the opportunity to find the right balance between burn time and weight. The Trail Runner connection cable enables the use of either our USB rechargeable or alkaline battery – or why not both! Combine them in any way that suits your needs. The colder it gets the less battery capacity. The battery capacity could depend on your body heat as well as the outside temperature. The long extension cord from SILVA gives you the option to carry the battery close to your body. This could be crucial in many ways. Keeping the battery as warm as possible in cold weather extends its burn time.
