Cameron Sino heated apparel battery

The Cameron Sino MW74V22-SF is a 7.4V replacement battery built for Mobile Warming Baselayers including Ion Base Layer Pants, Primer Pants and Primer Shirts. It restores power to heated garments that use the MW74V22-SF part number, so outdoor workers and winter sports users can keep their existing kit working.

Thermals noise and power draw

The 2000mAh cell stores 14.80Wh of energy and delivers a steady 7.4V output during normal heating cycles. No moving parts mean silent operation, and the lithium chemistry runs cool against the body while supplying consistent power to the garment heating elements.

Upgrade path and fit

This unit replaces a depleted or lost MW74V22-SF pack in compatible Baselayer items; it is not a higher-capacity alternative and will not fit non-Mobile Warming heated clothing. The jump is worth it when the original battery no longer holds enough charge for a full shift or ride.

Questions about this item

How do I install the MW74V22-SF battery in my heated Baselayer garment?

Locate the zippered battery pocket on your Ion or Primer garment, insert the 7.4V pack with the connector facing the port, press firmly until the plug clicks into place, then close the pocket before powering on.

What maintenance will the MW74V22-SF need over time?

Recharge after each use, store at room temperature during off-season, and replace the pack once run-time falls noticeably below the rated 14.80Wh capacity.

What limit appears first during continuous heating with this 2000mAh pack?

The 14.80Wh energy capacity determines total run-time, so the battery will deplete before any thermal or voltage limit is reached under normal heated-apparel loads.
