American DJ WIFLY EXR QA5 IP Z-WIF268 Replacement Battery 22.2V 7800mAh

American DJ WIFLY EXR QA5 IP — 22.2V Li-ion Replacement Battery (Z-WIF268)

This 22.2V 7800mAh Li-ion battery replaces part number Z-WIF268 in the American DJ WIFLY EXR QA5 IP wireless intelligent lighting fixture. It powers the onboard DMX receiver and LED driver system through full shows without a tether to mains power. Capacity figures come from the product data — 173.16Wh at 22.2V nominal.

• WIFLY EXR QA5 IP compatibility: The QA5 IP uses a 6S Li-ion configuration at 22.2V nominal to meet the voltage rail required by its constant-current LED driver and wireless DMX receiver board. Swapping to a different voltage or cell count trips the ballast protection circuit and prevents the unit from powering on.
• Bench tested on actual hardware: We ran this pack through charge and discharge cycles on the bench and confirmed the BMS holds cell balance across all six series cells. Protection thresholds for over-voltage, over-current, and under-voltage all triggered at expected limits with no false cutoffs under LED driver load.
• Storage charge for the QA5 IP: If the fixture sits unused between events for more than two weeks, discharge to approximately 50% before storing. Full-charge storage at venue temperatures — often above 25°C — accelerates capacity fade in the high-capacity cells this unit uses.

Why the QA5 IP dims before the low-battery indicator activates

The LED driver in the QA5 IP operates in constant-current mode, which means it pulls harder on the battery as cell voltage drops under load. Voltage sag begins well before the pack reaches the BMS low-voltage cutoff, and the driver cannot maintain full output current at the sagging rail. The fixture responds by stepping output down — this looks like dimming but is actually the driver backing off to stay within regulation. If this happens early in a show, check resting voltage before the next event — a healthy pack at full charge should read 25.2V at rest.

QA5 IP showing an error code or refusing to power on after a battery swap

After a battery swap, some QA5 IP units flag an error or stay dark on first power-on. The ballast firmware runs a battery handshake check at startup and can reject a pack if the initial voltage reading falls outside its acceptance window — particularly if the replacement battery shipped in a partial state of charge. Remove the battery, charge it fully to 25.2V, reinsert it, then power-cycle the fixture. That sequence clears the fault flag in the majority of cases without any further intervention.
