Fieldsheer 7.4v Powersheer™ XL Plus Battery Battery and Cable

XL Plus Battery

More power. Longer heat. Smarter performance. The Powersheer™ XL 7.4V Battery is the ultimate upgrade for anyone looking to extend the runtime of their Fieldsheer heated gear. With a 4000mAh capacity, this high-output Li-Ion battery delivers double the heat duration compared to standard models-perfect for long workdays, multi-day trips, or frigid environments where lasting warmth matters.

Compatible with all Fieldsheer 7.4V Heated Jackets, Vests, and Baselayers, this battery also comes standard in our Men's and Women's Adventure Jackets and Universal Handwarmer. The Micro-USB input makes charging easy (USB-A to Micro-USB cable included), while the built-in USB port lets you charge phones or other devices on the go. It even features a built-in LED flashlight-because when conditions get extreme, every detail counts.
