Both devices use the same LB-1 cell format and connector. When the original battery degrades, audio transmission becomes unstable before it fails completely.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eTX-M2 and VideoMic Pro+ cell compatibility:\u003c\/strong\u003e\n    Both units draw from the same 3.7V nominal rail and use an identical LB-1 cell footprint with the same connector pinout. The BMS in each device reads cell voltage and temperature — a cell that doesn't match the expected charge curve will trigger early low-battery warnings.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through charge and discharge on the TX-M2 transmitter. The BMS accepted the cell without fault flags, reached full charge voltage at 4.2V, and the transmitter maintained stable RF output through the full discharge cycle without dropout.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eTX-M2 transmitter storage tip:\u003c\/strong\u003e\n    If the transmitter sits unused for several weeks, the BMS may lock the cell out at startup due to voltage dropping below the reinitialisation threshold. Plug the transmitter into USB-C charge for at least 15 minutes before attempting to power on — this wakes the BMS before the cell voltage climbs back into normal operating range.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the TX-M2 shows full battery then cuts out mid-performance\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eA degraded LB-1 cell holds its open-circuit voltage near 3.7V at rest, so the transmitter displays a full or near-full indicator. Under the sustained RF transmit draw of a live performance, internal cell resistance causes voltage to sag rapidly. The TX-M2 BMS reads this sag as a low-cell condition and shuts the transmitter down to protect the cell — even though the indicator showed green moments earlier. Replacing the cell is the fix; a resting voltage check alone will not reveal the problem.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eReceiver losing RF lock on the TX-M2 after a battery swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eAfter fitting a new LB-1 cell and powering the TX-M2 back on, the receiver may show an unlinked or searching status. This happens because the transmitter re-initialises its RF output from scratch on a fresh power cycle, and the receiver does not always reacquire automatically. Hold the TX-M2 power button until the transmitter LED stabilises, then perform a rescan or channel lock from the receiver end. The link should re-establish once the transmitter is outputting a stable RF signal at the paired frequency.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381523349594,"sku":"BWCS-RTX200SL-1","price":27.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381523382362,"sku":"BWCS-RTX200SL-2","price":31.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381523415130,"sku":"BWCS-RTX200SL-3","price":34.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-RTX200SL-1.webp?v=1778901370","url":"https:\/\/batteryweb.com\/products\/rode-performer-tx-m2-replacement-battery-37v-1300mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
