The Macna 7.4V / 3A Dual Smart Battery Set is the flagship accessory for those seeking maximum runtime for heated gloves and socks. This kit provides two Li-Po batteries which, with a combined output of 22W (7.4V x 3A), offer up to an exceptional 9.5 hours of comfortable heat.
The distinguishing feature is the Power Expansion System™ (PES): an ergonomic solution that divides the total capacity into multiple, connected smaller batteries. This design successfully avoids the bulk typically created by a single large battery on the wrist.
Plug & Play technology is another major benefit: thanks to the internal processor, the battery powers on automatically as soon as it is connected to your accessory, ensuring immediate, safe, and efficient use. The kit includes the two batteries and a charger.
