It slots into the same battery bay and uses the same contact layout as the original pack. Capacity is rated at 2200mAh (15.84Wh) — matching the stock specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e302 \/ 353 \/ 354 \/ 361 compatibility:\u003c\/strong\u003e\n    These models share the same 7.2V two-cell Ni-MH voltage rail and identical battery bay dimensions. The contact alignment and BMS handshake protocol are consistent across the series, so one pack covers all listed units 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 full charge and discharge on a 302-series body. The BMS accepted the charge sequence without interruption, and transmit-current draw stayed within the rated window across multiple PTT cycles.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst insertion into the charger dock:\u003c\/strong\u003e\n    If the dock LED flashes fault on first seating, remove the pack, wipe the gold contact strip with a dry cloth, and reseat firmly. The Radon dock requires a clean contact cycle to complete its BMS handshake before charging begins.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Radon 302 cuts out mid-transmission on a fresh pack\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells ship at storage voltage — typically 1.1–1.2V per cell, giving a pack voltage around 6.6–7.2V before conditioning. When you press PTT, the transmitter draws a short high-current spike. If the pack hasn't completed its first full charge cycle, that spike can pull cell voltage below the BMS cutoff threshold and trip a momentary disconnect. Run one full charge before the radio goes into active use. After the first complete cycle, the cells stabilise and the cutout behaviour stops.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBar indicator reading one bar low on a fully charged pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Radon 302 uses a simple voltage-threshold bar display — each bar corresponds to a voltage window, not a percentage. A new Ni-MH pack that hasn't been conditioned sits at a resting voltage just below the top threshold, so the radio displays one fewer bar even after a full charge. This isn't a fault with the pack. Run one complete discharge-to-charge cycle and the resting voltage will settle into the correct top-bar window — typically above 8.0V open circuit.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426312355930,"sku":"BWCS-TAP810TW-1","price":52.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426312388698,"sku":"BWCS-TAP810TW-2","price":61.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426312421466,"sku":"BWCS-TAP810TW-3","price":68.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-TAP810TW-1.webp?v=1779930680","url":"https:\/\/batteryweb.com\/products\/radon-302-replacement-battery-72v-2200mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
