American DJ Z-MEB236 Mega Go PAR64 Compatible Battery 11.1V 10200mAh

American DJ Mega Go PAR64 RGBA — 11.1V Li-ion Replacement Battery (Z-MEB236)

This 11.1V 10200mAh Li-ion battery replaces the OEM pack in the American DJ Mega Go PAR64 RGBA and Jelly Go PAR64 RGBA portable LED fixtures. Both fixtures run the same battery platform — same voltage rail, same connector, same BMS handshake. Capacity is rated at 113.22Wh from the factory-spec cell configuration.

• Mega Go and Jelly Go PAR64 RGBA compatibility: Both fixtures share the Z-MEB236 battery platform. The 11.1V nominal rail, physical connector, and BMS communication protocol are identical across both models, so one replacement covers either fixture without modification.
• Bench tested on actual hardware: We ran this pack through full charge and discharge cycles on the PAR64 RGBA fixture. The BMS handled constant-current LED driver load without tripping, and cell balancing completed normally at end-of-charge.
• Storage charge for event fixtures: Store this battery at approximately 50% state of charge if the fixture will sit unused for more than two weeks. Full-charge storage in a warm venue bag or flight case accelerates capacity fade in the high-capacity cells used in this pack.

Light dimming before the battery indicator reaches low

The PAR64 RGBA's LED driver runs in constant-current mode, which pulls harder on the cells as voltage drops. When cell voltage sags under that sustained draw, the fixture dims output before the onboard indicator triggers a low-battery warning. This is voltage sag, not a faulty indicator. A battery with degraded cells will show this earlier in the discharge cycle than a fresh pack. If dimming starts well before the indicator, swap the battery and check the old pack's resting voltage — anything below 9.9V at rest indicates cell wear.

Fixture shows an error code or won't accept battery after extended storage

If a battery has sat discharged for several weeks, individual cells can fall below the acceptance threshold the fixture's ballast firmware checks on power-up. The BMS on the battery itself may also enter a protection state and block output entirely. To recover, connect the battery to a compatible Li-ion charger and apply a low-current charge for 15–30 minutes before reinserting it into the fixture. If the fixture still throws an error after that, power-cycle the unit with the battery seated — most ballast firmware clears the fault flag on a clean boot once cell voltage reads above 10.5V.
