It replaces OEM part numbers BPL30, VM-BPL27, and VM-BPL27A. The cell fits the original battery bay and connects to the camcorder's onboard BMS via the same contact arrangement as the factory pack.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCC-8251, PRO-V730, and PRO-V742 compatibility:\u003c\/strong\u003e\n    These three RCA camcorder models share the same battery bay dimensions, 7.4V voltage rail, and BPL30-series connector pinout. One replacement cell covers all three bodies without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through full charge and discharge on the CC-8251 body. The BMS accepted the pack without error flags and voltage under record load held above the 6.8V low-cell threshold throughout testing.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst charge via camcorder body:\u003c\/strong\u003e\n    On first install, charge this cell inside the camcorder body rather than a third-party charger. The CC-8251's BMS runs an initialisation handshake on the first in-body charge cycle, which sets the reference point for the battery-remaining indicator. Skipping this step can cause the indicator to read inaccurately from the start.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eDead battery indicator on the CC-8251 with a partially charged replacement cell\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe CC-8251 maps its battery-remaining display to a voltage-threshold curve calibrated for the original BPL30 discharge profile. A new aftermarket cell can have a slightly different discharge slope, causing the camera to report empty while the cell still holds usable charge. This is a calibration mismatch, not a cell fault. Running two or three full charge-to-discharge cycles through the camcorder body allows the BMS to re-map its thresholds to the new cell's actual curve. After conditioning, the indicator stabilises and tracks remaining charge accurately.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery percentage jumping erratically during recording\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eIf the percentage display on the CC-8251 skips non-linearly — say, dropping from 60% to 30% in seconds or jumping back up — the BMS voltage-to-percentage lookup table is misreading the new cell's discharge curve. This most often happens when the pack has not completed a full initialisation cycle inside the camera body. Charge the battery to 100% through the camcorder, record until the camera shuts off on low-battery cutoff, then recharge fully. One complete in-body cycle is usually enough to re-anchor the percentage readout to the correct voltage points.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333898207322,"sku":"BWCS-SVBD2-1","price":35.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333898240090,"sku":"BWCS-SVBD2-2","price":40.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333898272858,"sku":"BWCS-SVBD2-3","price":44.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SVBD2_1.webp?v=1778213591","url":"https:\/\/batteryweb.com\/products\/rca-cc-8251-replacement-battery-74v-4000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
