About this replacement
Fly Racing Title Heated Glove — 7.4V Li-ion Replacement Battery (5884)
This 7.4V, 1100mAh Li-ion battery replaces the factory power pack in Fly Racing Title, Radiant, and Ignitor heated gloves. It feeds the resistive heating elements embedded in the glove panels. When your original pack no longer holds a useful charge, this cell restores full heating function across all heat settings.
- Title, Radiant, and Ignitor glove compatibility: These gloves share the same 7.4V power rail, connector format, and BMS handshake protocol. The same cell works across all three because Fly Racing standardised the battery interface across this range — swapping to a different voltage cell will lock out the heat controller.
- Bench tested on actual hardware: We ran this cell through full charge and load cycles on a 7.4V heated glove controller. The BMS held stable under sustained current draw at maximum heat setting, and low-voltage cutoff triggered cleanly without latching the controller in fault state.
- Cold-weather operation tip: Start on the lowest heat setting for the first 10 minutes on a new battery — the heating elements draw significant current at maximum, and a new cell benefits from a short warm-up period before full-power operation. This also applies after the pack has been stored cold, since Li-ion capacity temporarily reduces below 10°C.
Why the highest heat setting stays locked out on a new pack
The heat controller in Fly Racing gloves monitors pack voltage before enabling the top heat level. A new cell shipped at storage voltage — typically around 3.7V per cell, or 7.4V nominal — can sit just below the threshold the firmware requires to unlock maximum output. Charge the pack fully to 8.4V before the first ride. If high heat is still unavailable after a full charge, check that the connector is fully seated — a partial connection drops apparent voltage at the controller input.
Heating element cuts out mid-ride on maximum setting
Maximum heat setting draws roughly 3–4× the current of the lowest setting. When cell capacity has degraded, internal resistance rises, and sustained high-current draw causes pack voltage to sag below the BMS protection threshold — triggering a mid-use cutoff. The BMS is protecting the cell, not failing. Switch to medium heat for the remainder of the ride, then charge fully. If cutout happens consistently within a short period of use at maximum, the cell has degraded and replacement is the correct fix.
