It slots into the same battery compartment as the original and runs the panel at full output. Capacity figures come from the product specification, not inflated marketing claims.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eAL-528 and AL-F7 platform fit:\u003c\/strong\u003e\n    The 528C, 528S, 528W, and AL-F7 share the same battery form factor, connector pin layout, and 7.4V input rail. One battery type covers all four panels — there is no electrical difference at the battery interface between them.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through full charge and discharge cycles on the AL-528 platform. The BMS held voltage within spec across the discharge curve and tripped the low-voltage cutoff cleanly before the cell could be damaged.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eLED panel draw tip:\u003c\/strong\u003e\n    The AL-528C pulls more current at full brightness with colour mixing active than in single-channel white mode. If you run colour LEDs at 100%, expect heavier draw than the rated 14.8Wh suggests at lower brightness settings — dial brightness to match shoot length.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the AL-528C flickers or cuts out on a new battery\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe AL-528C does not have a sophisticated BMS authentication handshake the way camera bodies do, but it does respond to voltage sag under high current draw. A cell with elevated internal resistance — whether aged or counterfeit — will sag below the panel's minimum operating voltage during a full-brightness burst. That sag reads as a supply interruption, and the panel cuts out momentarily. A genuine 7.4V cell with low internal resistance sustains voltage under load and prevents this dropout.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery indicator showing full, then panel dies without warning\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe AMARAN AL-528 series uses a simple LED fuel gauge rather than a coulomb-counting circuit. It reads resting voltage, not actual state of charge under load. A cell that reads 8.2V at rest can still sag hard once the LEDs fire at full power. The indicator stays green until the cell collapses, then the panel shuts off abruptly with no warning stage. Check resting voltage with a multimeter — a healthy fully charged 7.4V Li-ion cell should read between 8.3V and 8.4V.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333925896282,"sku":"BWCS-F550-1","price":37.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333925929050,"sku":"BWCS-F550-2","price":41.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333925961818,"sku":"BWCS-F550-3","price":45.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-F550-1.webp?v=1778213575","url":"https:\/\/batteryweb.com\/products\/aputure-amaran-al-528c-replacement-battery-74v-2000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
