It slots into the same battery bay as the original Canon pack and connects via the same multi-pin interface. Capacity is 3000mAh (22.2Wh), matching the standard specification for this camcorder line.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMV-series platform fit:\u003c\/strong\u003e\n    Canon's MV-series camcorders share a common battery bay geometry and a consistent 7.4V two-cell Li-ion configuration across the range. The BP-522 connector pinout and physical form factor cover the full lineup, so the same pack works across DM-MV30 through DM-MV400 and related variants without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge and discharge cycles on a DM-MV100X body. The onboard BMS accepted the cell after one full charge cycle via the Canon charger, and the battery-remaining indicator tracked normally throughout discharge with no mid-session cutoff events.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst charge via Canon charger:\u003c\/strong\u003e\n    Some MV-series bodies require the initial charge to complete through the OEM charger rather than the in-body USB path — this lets the camera BMS map the new cell's discharge curve and report remaining charge accurately from the first recording session onward.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCanon MV-series BMS rejecting a new BP-522 on first install\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eCanon MV-series camcorders run a handshake between the body and the battery's protection circuit on every power-on. A new third-party cell that hasn't completed a charge cycle through the Canon charger can fail this check, causing the body to display a battery warning or refuse to power on entirely. The fix is straightforward: seat the battery, connect the Canon charger, and allow a full charge to 8.4V before powering the camera body. After that first cycle, the BMS accepts the cell and the issue doesn't recur.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery percentage jumping erratically during recording\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the camera's fuel gauge is still calibrated to the discharge curve of an aged original cell rather than the new BP-522. The indicator may read 80%, drop to 40% in a short span, then stabilise — not because the cell is faulty, but because the voltage-threshold map doesn't yet match the new cell's curve. Run two full charge-discharge cycles through the Canon charger, letting the battery reach 8.4V on charge and discharge fully before recharging. After those conditioning cycles, the percentage display tracks the actual cell state accurately.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333878612058,"sku":"BWCS-BP522-1","price":33.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333878644826,"sku":"BWCS-BP522-2","price":38.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333878677594,"sku":"BWCS-BP522-3","price":42.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BP522_1.webp?v=1778213540","url":"https:\/\/batteryweb.com\/products\/canon-dm-mv100x-replacement-battery-74v-3000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
