Klan-e 7.4V Heated Gloves Replacement Battery 3000mAh

Klan-e Heated Gloves & Socks — 7.4V Li-Polymer Replacement Battery (K-BAT-7.4VOLT-3.0A)

This is a 7.4V 3000mAh (22.2Wh) lithium-polymer replacement battery for Klan-e heated gloves and socks. It slots directly into the original battery compartment and powers the resistive heating elements through the same BMS interface as the factory pack. Order this when the original cell no longer holds a useful charge across a full outing.

• Gloves and socks share this pack: Both products run off the same 7.4V nominal voltage rail with an identical connector and BMS handshake, which is why Klan-e uses one battery part number across the two garments. Swapping between gloves and socks is straightforward — the pack draws current according to the heating element it's connected to.
• Bench tested on actual hardware: We cycled this battery through low, medium, and high heat settings and monitored BMS cutoff behaviour at each draw level. The protection circuit held steady during sustained high-setting pulls and recovered correctly when the load was removed and reapplied.
• First use on a new pack: Run the gloves or socks on the lowest heat setting for the first 10 minutes before switching to maximum. The heating elements draw significantly more current at full power, and letting the new cell stabilise under a lighter load first helps the BMS calibrate its charge state accurately from cycle one.

Why Klan-e heated gloves stop reaching maximum heat on a new battery

A fresh lithium-polymer cell sometimes reads a slightly lower resting voltage than its true state of charge until the first full charge-discharge cycle completes. The Klan-e BMS uses voltage thresholds to gate the high heat setting — if the pack reads below roughly 7.2V under load, the controller won't sustain full current to the heating elements. Charging the replacement pack to 100% before the first use resolves this. After one complete cycle, the BMS recalibrates and the high setting operates as expected.

Heating element cuts out mid-use then restarts on its own

This is a BMS overcurrent trip, not a faulty heating element. At maximum setting the draw from Klan-e heated gloves is sustained and continuous — if the pack temperature rises or the cell voltage sags briefly under that load, the protection circuit interrupts current flow as designed. The restart happens once the BMS clears the fault condition, typically within a few seconds. Dropping to the medium heat setting reduces current draw enough to prevent repeated trips. If cutouts persist on medium, check that the battery contacts are clean and fully seated — partial contact increases resistance and amplifies voltage sag.
