IXS Heat-ST Gloves 7.4V Replacement Battery MWBT2-IXS 2000mAh

IXS Heat-ST Gloves — 7.4V Li-Polymer Replacement Battery (MWBT2-IXS)

This is a 7.4V, 2000mAh lithium-polymer replacement battery for the IXS Heat-ST Gloves. It slots into the battery compartment on each glove and powers the embedded heating elements directly. Two cells are included — one per glove — matching the original MWBT2-IXS specification at 14.8Wh total.

• Heat-ST Gloves compatibility: The MWBT2-IXS cell runs at 7.4V nominal to match the heating element voltage rail in the Heat-ST platform. Swapping to a different voltage will either under-drive the elements or trip the glove's onboard protection circuit.
• Bench tested on actual hardware: We ran each cell at sustained draw across all heat settings. The BMS held stable at low and mid settings; at maximum, current draw spiked as expected and the protection circuit responded correctly with no false cutoffs during normal cycling.
• First-use heat setting protocol: Start on the lowest heat setting for the first 10 minutes with a new cell. The heating elements pull significant current at maximum, and a fresh lithium-polymer cell benefits from operating at a lower draw before full power is demanded.

Heating element cutting out mid-use on maximum setting

At maximum, the heating elements in the Heat-ST Gloves draw sustained high current — the BMS is set to cut power if that draw exceeds its protection threshold, even briefly. A degraded or cold cell hits its internal resistance limit faster, which triggers the cutoff before the element reaches temperature. This is not a glove fault — it is the battery's BMS protecting the cell from over-discharge under load. Switch to medium setting to recover, then step back up slowly once the cell has stabilised above 7.0V under load.

Glove not reaching full heat level despite a full charge

If the glove runs but never gets as hot as it should, the cell voltage is sagging under load before the heating element can reach full operating temperature. This typically means the original battery has lost enough capacity that resting voltage looks fine at 8.4V fully charged, but voltage collapses toward 6.8V the moment the element draws current. A new 2000mAh cell at 7.4V nominal restores the sustained voltage the heating circuit needs. Check resting voltage first — if the old cell reads below 7.0V at rest, replacement is the fix.
