These are broadcast-grade cameras used in field production and studio work, where sustained high-draw operation is the norm. The cell chemistry and BMS output are matched to the BP-V142 specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePMW-EX330 \/ F5 \/ F55 \/ PMW-400 platform fit:\u003c\/strong\u003e\n    These models share the BP-V142 form factor, V-mount locking interface, and 14.8V nominal rail. The BMS handshake protocol is consistent across this camera family, so a single cell spec covers the group without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell on the PMW-EX330 and cycled it through full discharge under continuous 4K record load. The BMS held the output rail within spec and triggered low-voltage cutoff at the correct threshold — no premature shutdown and no runaway discharge.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst charge protocol on Sony broadcast bodies:\u003c\/strong\u003e\n    Insert the battery and run a full charge cycle through the OEM Sony charger or the camera body itself before heavy use. Some Sony broadcast BMS systems require one complete charge cycle from within the recognised charger chain before the battery-remaining indicator maps correctly to the new cell's discharge curve.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the PMW-EX330 rejects a new BP-V142 replacement on first insert\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe PMW-EX330 uses a multi-pin authentication check over the battery communication bus before accepting a new cell. A fresh replacement cell that has never been charged in an OEM Sony charger may not pass this check on the first cold insert. The camera body reads the BMS as unverified and blocks power delivery. One full charge cycle through a Sony BC-L160 or compatible OEM charger resets the authentication state and resolves the rejection on next insert.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery percentage jumping erratically on the PMW-EX330 display\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the camera's internal fuel gauge maps its voltage thresholds against the original BP-V142's discharge curve, and the replacement cell's curve sits slightly differently at mid-charge. The indicator can jump from 60% to 35% or climb back up as load changes. This typically stabilises after two to three full discharge-and-recharge cycles, which allow the BMS to recalibrate against the actual cell behaviour. If the jumping persists past three cycles, check that the resting voltage after a full charge reads at or above 16.4V before inserting.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333638226010,"sku":"BWCS-SBP142MC-1","price":224.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333638258778,"sku":"BWCS-SBP142MC-2","price":262.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333638291546,"sku":"BWCS-SBP142MC-3","price":291.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SBP142MC-1.webp?v=1778213032","url":"https:\/\/batteryweb.com\/products\/sony-pmw-ex330-replacement-battery-148v-9600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
