It fits the beltpack transmitter unit that keeps crew members wireless during live production, broadcast, or aviation ground ops. Capacity is rated at 6.66Wh — matching OEM spec from the product data.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eTempest beltpack compatibility:\u003c\/strong\u003e\n    The Tempest 2.4GHz platform shares a common cell footprint and connector across the beltstation and beltpack variants. Each unit uses the same BMS handshake voltage window, so one cell spec covers the full Tempest range listed above — no adapter needed.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell under combined DECT radio and audio draw to confirm the BMS holds within the Tempest's operating voltage window. No premature cutoff, no thermal fault flagged during sustained transmission cycles.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle base station registration:\u003c\/strong\u003e\n    Dock the beltpack in the base station and let it complete one full charge before going live. The Tempest base logs the new cell's state-of-charge curve during that first cycle — skip it and the talk-time indicator reads inaccurate until the calibration completes.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBase station not recognising the new pack after swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eWhen a replacement cell arrives at storage voltage (typically 3.6–3.7V), the Tempest base station may not recognise the pack as ready to charge. The BMS handshake requires the cell to be within the base's expected initialisation range before the charge LED confirms pairing. If the dock shows no charge indicator or flashes an error, the cell has not completed the handshake cycle. Seat the pack firmly, leave it on the dock undisturbed for a full charge cycle, and the base will register it correctly.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eHeadset cuts out mid-transmission on a freshly charged pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Tempest beltpack draws from two loads simultaneously — the 2.4GHz radio and the audio circuit. Under peak transmission, combined current draw can momentarily pull cell voltage below the BMS cutoff threshold, triggering a dropout that looks like a dead battery. This is most common in the first few charge cycles before the cell's internal resistance stabilises. Run three to five full charge-discharge cycles and the cutoff threshold behaviour normalises. If dropouts persist past cycle five, check that the cell seated fully and the contact pins are clean — a partial connection raises resistance and triggers the same symptom at a higher voltage.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43428121215066,"sku":"BWCS-HMT200TS-1","price":35.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43428121247834,"sku":"BWCS-HMT200TS-2","price":41.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43428121280602,"sku":"BWCS-HMT200TS-3","price":45.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HMT200TS-1.webp?v=1779934163","url":"https:\/\/batteryweb.com\/products\/hme-tempest-24ghz-beltstation-replacement-battery-37v-1800mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
