These radios are used in aviation, maritime, and emergency services where voice transmission cannot drop out. Voltage and capacity match the original pack specification exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eTHR850 \/ THR880 \/ THR880i platform fit:\u003c\/strong\u003e\n    All three models share the same battery bay geometry, connector pinout, and BMS handshake voltage. A single cell format covers the entire series without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through transmit cycles on the THR880 platform and confirmed the BMS held correct voltage under PTT-triggered current spikes. No overcurrent trip occurred during sustained transmission bursts.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst insertion on the charger dock:\u003c\/strong\u003e\n    If the dock LED shows a fault on first seating, remove the pack, wipe the gold contact strip with a dry cloth, and reseat firmly. The THR series charger requires a clean contact cycle to accept the 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 THR850 cuts out mid-transmission on a new battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA new Li-ion cell ships at storage voltage — typically 3.6–3.8V — not at full charge. When the radio draws transmit current at that voltage, the BMS can interpret the load spike as an overcurrent event and cut the output. This is not a faulty pack. Fully charge the battery before the first transmission session. Once the cell is above 4.1V, the BMS handles PTT spikes without interruption.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBar indicator showing one fewer bar than expected after a full charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe THR series uses a voltage-threshold bar indicator, not a fuel gauge chip. Each bar maps to a fixed voltage window. A new cell can sit slightly below the top threshold immediately after charge if the charger terminates early on the first cycle. Run one full discharge and recharge cycle. After that, the cell stabilises at its true resting voltage and the indicator reads correctly.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426373337178,"sku":"BWCS-NKN4SL-1","price":30.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426373369946,"sku":"BWCS-NKN4SL-2","price":34.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426373402714,"sku":"BWCS-NKN4SL-3","price":37.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-NKN4SL-1.webp?v=1779931026","url":"https:\/\/batteryweb.com\/products\/airbus-thr850-replacement-battery-37v-2000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
