Anyone who has crossed the Alps in early spring, ridden through Scandinavia in autumn or climbed a mountain pass at first light knows how quickly the cold works its way under your motorcycle jacket. The KLIM eFire Base and Mid Layer Battery is the rechargeable battery that powers your heated eFire base layers and mid layers. Compact, lightweight and built to ride all day in your inner pocket, so you can stay focused on the road or trail ahead.
Because the battery works independently of your motorcycle, you are never tied to cables or a connection to your bike's electrical system. That makes a real difference when you step off for a break, stop for a photo or pick up a dropped bike on a muddy section. Your heat source simply goes where you go. For off-road riders this is a genuine advantage: no plug that pulls loose during an unexpected move and no cable that snags.
On the road you want to carry as few different chargers as possible. Thanks to the USB-C connection, you charge this battery with the same cable as your phone or GPS. That works from a USB port on your bike, a power bank, a laptop charger or a wall socket at the campsite or hotel. With a capacity of 16.65 Wh, the battery stays well below the 100 Wh limit used by airlines, so you can take it in your hand luggage when you fly to your starting point or ship your bike ahead. Always check the current rules of your airline.
The LED indicator shows at a glance how much energy is left. That way you know over breakfast whether to top it up before setting off on a long ride through the mountains.
How long the battery lasts depends on the selected heat setting and the outside temperature. On cold days with lots of elevation, or on trips where you can't charge along the way, a second battery is a smart addition. While one battery is in use, the other sits fully charged in your tank bag or top case. If you ride with a travel partner who also wears eFire gear, a spare battery adds extra peace of mind.
This battery is designed for KLIM eFire heated base layers and mid layers. KLIM provides an overview of compatible eFire products, so you can be sure the battery matches the gear you already own or plan to buy.
With the right care, the eFire battery lasts for many seasons and remains a dependable part of your kit, from the first cold morning to the last ride of the year.
