These radios share the same battery bay geometry and contact layout, so one pack covers the full compatibility group. Capacity figure is taken directly from product specifications — 14.8Wh total energy.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eUV-5X \/ G11S \/ MU-5 \/ TD-H5 platform fit:\u003c\/strong\u003e\n    These four models run off the same 7.4V nominal rail, share an identical battery bay and contact strip layout, and use the same BMS handshake protocol — which is why a single GM-30 pack covers all of them without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through transmit loads on the UV-5X platform. The BMS handled the current spike at PTT press without tripping into overcurrent lockout, and the protection circuit held the discharge floor at the expected low-voltage cutoff threshold.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst insertion on the charging dock:\u003c\/strong\u003e\n    If the dock LED flashes a fault on first insertion, remove the pack, wipe the gold contact strip with a dry cloth, and reseat firmly — the UV-5X dock requires a clean contact cycle to register the new BMS before it begins a charge sequence.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the UV-5X drops to reduced TX power mid-shift on a new GM-30\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eA new Li-ion cell ships at storage voltage — typically 3.6–3.75V per cell, not full charge. Under sustained RF output, that lower starting voltage sags further under transmit load, and the radio's internal power management steps down TX output to protect the finals. This is not a faulty pack. A full charge cycle before extended use brings both cells to 4.2V each, which gives the radio the headroom it needs to hold rated output through a full shift without stepping down.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBar indicator showing one fewer bar than expected after inserting the GM-30\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe UV-5X reads voltage-threshold bars — it checks pack voltage and maps it to a bar count. A new cell at storage voltage sits below the top threshold, so the radio displays one bar fewer than full even with a brand-new pack installed. This is not a capacity defect. Charge the pack to 8.4V (4.2V per cell) on the dock until the LED goes green, then reinsert — the indicator will step up to the correct bar count.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426264285274,"sku":"BWCS-BAF130TW-1","price":43.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426264318042,"sku":"BWCS-BAF130TW-2","price":50.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426264350810,"sku":"BWCS-BAF130TW-3","price":55.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BAF130TW-1.webp?v=1779930493","url":"https:\/\/batteryweb.com\/products\/radioddity-uv-5x-replacement-battery-74v-2000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
