American DJ Z-WIB236 WIFLY BAR QA5 22.2V Replacement Battery

American DJ WIFLY BAR QA5 — 22.2V Li-ion Replacement Battery (Z-WIB236)

This is a 22.2V 7800mAh Li-ion replacement battery for the American DJ WIFLY BAR QA5 wireless LED bar. It fits the QA5 directly and matches the OEM Z-WIB236 specification. Capacity figure is drawn from product data at 173.16Wh.

• WIFLY BAR QA5 fit: The QA5 uses a 6S Li-ion pack at 22.2V nominal to feed the onboard LED driver. The connector pinout and BMS handshake on this replacement match the original Z-WIB236 pack, so the fixture accepts it without flagging a battery fault on startup.
• Bench tested on actual hardware: We ran this pack through charge and discharge cycles on the QA5 platform. The BMS held cell balance across all six series cells and tripped protective cutoff at the correct low-voltage threshold without triggering a false fault on the fixture's battery status circuit.
• Pre-show storage tip: Store the QA5 battery at roughly 50% state of charge if it will sit unused for more than two weeks. Full-charge storage at room temperature or above accelerates capacity fade in high-capacity 6S packs — the elevated voltage across all six cells speeds electrolyte degradation between gigs.

QA5 dimming before the battery indicator hits low

The WIFLY BAR QA5 LED driver operates in constant-current mode, which pulls harder on the battery as cell voltage drops under load. A pack with degraded capacity sags below the driver's regulation threshold before the battery indicator registers low — so the fixture steps output down to protect itself while the gauge still shows charge remaining. This is voltage sag, not a faulty indicator. A fresh 22.2V pack at full capacity holds the voltage rail stable enough for the driver to maintain full output through most of the discharge curve.

Battery not recognised by the QA5 after sitting in storage

If a Li-ion pack self-discharges below the fixture's acceptance threshold during storage, the QA5 ballast circuit will not initialise the battery and the unit may appear completely dead. The BMS inside the pack also has its own low-voltage lockout — once cells drop below roughly 2.5V per cell (15V pack total on a 6S), the BMS opens the output and refuses to communicate. Connect the pack to a Li-ion charger that supports a recovery or wake-up mode, allow it to trickle charge until the BMS closes the circuit, then perform a normal charge to 25.2V before reinstalling.
