It slots directly into the fixture to restore cordless operation for stage, event, and location lighting work. The Z-MEB846 matches the original voltage rail and connector so the fixture's LED driver receives the input it expects.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMega Go Flood Par Ho platform fit:\u003c\/strong\u003e\n    The Mega Go Flood Par Ho runs a constant-current LED driver that requires a stable 11.1V three-cell Li-ion pack. A mismatched voltage or incompatible BMS handshake causes the driver to reject the pack or trigger an undervoltage fault at startup. This battery matches the original cell configuration and BMS output the driver checks on power-up.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this battery through full charge and discharge cycles on the Mega Go Flood Par Ho. The BMS handled the LED driver's constant-current draw without triggering an overcurrent cutoff, and the protection circuit responded correctly at low-cell thresholds.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eStorage charge for location lighting:\u003c\/strong\u003e\n    Store this battery at roughly 50% state of charge if the fixture sits unused for more than two weeks. A fully charged high-capacity Li-ion pack held at elevated temperature — common in cases left in vehicles or on stage rigs — accelerates capacity fade in the cells faster than partial-charge storage does.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Mega Go Flood Par Ho dims before the battery indicator hits low\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe fixture's LED driver operates in constant-current mode, which means it pulls harder from the battery as cell voltage begins to sag. As the pack depletes toward its lower voltage range, cell internal resistance rises and the pack can no longer sustain the voltage the driver demands at full output. The driver responds by stepping the LED array down before the onboard fuel gauge registers a low reading — because the gauge measures state of charge, not instantaneous voltage under load. If you see this stepping at what appears to be mid-charge, check resting cell voltage with a multimeter: a healthy pack at 50% charge should read above 11.0V with no load applied.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eFixture shows an error code immediately after installing a replacement battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Mega Go Flood Par Ho's ballast firmware runs a battery presence and voltage check on every power cycle. If a replacement pack has been in storage, cell voltage can sit below the ballast's acceptance threshold — typically around 10.5V for a three-cell pack — and the firmware throws a fault rather than attempting to charge or operate. Connect the battery to its charger first and bring it to at least a partial charge before installing it in the fixture. Once cell voltage clears the acceptance floor, power cycle the fixture and the error code clears without any further reset procedure.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381323759706,"sku":"BWCS-ADM846SL-1","price":65.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381323792474,"sku":"BWCS-ADM846SL-2","price":76.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381323825242,"sku":"BWCS-ADM846SL-3","price":85.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ADM846SL-1.webp?v=1778899986","url":"https:\/\/batteryweb.com\/products\/american-dj-mega-go-flood-par-ho-replacement-battery-111v-5200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
