These are compact wireless microphone units used in run-and-gun video production and on-location audio capture. When the original cell ages or fails to hold charge, this replacement restores full operating capacity.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eVmicLink5 receiver and transmitter compatibility:\u003c\/strong\u003e\n    The RX+ receiver and TX transmitter units across the VmicLink5 series share the same 7.4V cell format, connector pinout, and physical envelope — 49.22 × 32.73 × 14.10mm. One cell spec covers both ends of the wireless link.\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 VmicLink5 units and confirmed the BMS accepted charge normally, held voltage within spec, and showed no premature cutoff under standard audio-transmission load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-use cycle for transmitter pairing:\u003c\/strong\u003e\n    On first install in a TX bodypack, complete one full charge before powering on. Some VmicLink5 transmitters flag a low-cell warning if voltage reads below 7.2V at startup — a full charge from flat prevents a false low-battery lockout on first use.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the VmicLink5 RX+ shows a dead-battery indicator on a freshly installed cell\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe VmicLink5 receiver maps its battery indicator to voltage thresholds calibrated against the original cell's discharge curve. A new Li-ion cell at rest voltage — typically around 3.7V per cell, or 7.4V combined — can register as depleted if the unit reads open-circuit voltage before the cell has been charged. The fix is straightforward: install the cell, connect to the OEM USB charger, and run one full charge cycle before powering the receiver on for operation. After that first charge, the indicator tracks accurately.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery percentage jumping erratically on the RX+ display during a shoot\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eErratic percentage readings on the VmicLink5 RX+ usually mean the unit's fuel gauge is interpolating against a discharge curve that doesn't yet match the new cell. This happens most often in the first two to three charge cycles on a replacement cell, before the BMS has profiled the cell's actual capacity. The percentage stabilises as cycle count increases. If the jumping persists past three full cycles, check that resting voltage measures at or above 7.3V with a multimeter — a cell reading below that at rest after a full charge indicates a cell fault.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333695602778,"sku":"BWCS-CNE170MX-1","price":24.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333695635546,"sku":"BWCS-CNE170MX-2","price":27.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333695668314,"sku":"BWCS-CNE170MX-3","price":30.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-CNE170MX-1.webp?v=1778213016","url":"https:\/\/batteryweb.com\/products\/saramonic-vmiclink5-rx-replacement-battery-74v-950mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
