When the original cell degrades and can no longer hold a working charge, audio drops out mid-take. This replacement restores full operating capacity to the unit.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eRX+ and TX+ shared battery platform:\u003c\/strong\u003e\n    The receiver and transmitter units in the VmicLink5 system share the same cell footprint — 49.20 × 32.90 × 14.00mm — and the same 7.4V voltage rail. One cell spec covers both ends of the wireless link, which matters if both units have aged together.\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 monitoring the BMS cutoff thresholds. The protection circuit trips cleanly at the low-voltage floor and accepts charge without thermal event at the full 7.4V nominal.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst charge after installation:\u003c\/strong\u003e\n    Complete one full charge cycle via the Saramonic OEM charger before use. Some wireless audio units map their battery-remaining indicator to a discharge curve calibrated on the first full cycle — skipping this step can cause erratic level readings on the unit's LED indicator.\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+ drops audio signal before the battery LED warns you\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe RX+ receiver draws current in bursts tied to RF processing — signal acquisition and re-lock events pull more current than steady-state receive. An aged cell with elevated internal resistance can't sustain these burst draws, so voltage sags below the BMS floor momentarily and the unit cuts out before the LED indicator registers low battery. A new cell with lower internal resistance eliminates the sag. If dropout persists after replacement, check the transmitter cell — both units need a healthy cell for stable RF link.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eTX bodypack transmitter showing solid red fault light after new cell install\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA solid red fault on the TX bodypack after fitting a new cell usually means the BMS on the unit has not completed its initialisation handshake with the new cell. This happens when the replacement cell ships at storage voltage — typically around 3.7V per cell, or 7.4V across the pack — rather than a full charge state. Connect the unit to the OEM charger and allow it to reach a full charge before powering on. Once the charge cycle completes and the LED shifts from red to green, the unit should boot normally and pair with the RX+ receiver.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333550735450,"sku":"BWCS-CNE170MU-1","price":43.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333550768218,"sku":"BWCS-CNE170MU-2","price":51.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333550800986,"sku":"BWCS-CNE170MU-3","price":56.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-CNE170MU-1.webp?v=1778212934","url":"https:\/\/batteryweb.com\/products\/saramonic-vmiclink5-rx-replacement-battery-74v-1000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
