It fits the Aviation, Tango, and A500 models. Swap it in when your original cell no longer holds charge through a full flight or ground operation.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eAviation, Tango, and A500 compatibility:\u003c\/strong\u003e\n    All three models share the same battery bay dimensions, connector pinout, and BMS handshake protocol — that is why one cell covers the entire range. Voltage rails and the charge management IC are identical across the platform.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through the base station charge circuit and confirmed the BMS completed its handshake without throwing a charge error. The protection IC responded correctly to both full-charge cutoff and low-voltage disconnect.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-charge protocol for aviation headsets:\u003c\/strong\u003e\n    Seat the new battery in the base station and let it complete one uninterrupted full charge cycle before your first call or flight. The base station must log the new cell to calibrate its talk-time estimate — skipping this step causes the indicator to read inaccurately for several cycles.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Aviation and Tango cut out mid-transmission on a new battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThese headsets draw from two loads at once — the audio amplifier and the DECT radio transmitter. When both fire together during active transmission, instantaneous current demand spikes sharply. A cell at storage voltage (around 3.6–3.7V, not yet conditioned) has higher internal resistance and may sag below the BMS cutoff threshold under that combined load. The headset powers off not because the cell is empty but because voltage dropped too fast. Run two or three full charge-discharge cycles through the base station and the internal resistance drops enough to handle the peak draw without tripping the cutoff.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBase station shows full charge but headset shuts off after a short session\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a storage-voltage issue, not a defective cell. A new Li-ion cell ships at roughly 40–50% charge to preserve cell chemistry in transit — the base station tops it up quickly and flags it as full, but the cell has not yet been through a complete cycle. The state-of-charge estimate the base uses is not accurate until the BMS has logged at least one full discharge. Place the headset in the base, charge to 100%, use it until the headset prompts a low battery, then return it to the base for a full charge — repeat this once more and the talk-time indicator will reflect actual capacity.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43428113088602,"sku":"BWCS-LHA500SL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43428113121370,"sku":"BWCS-LHA500SL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43428113154138,"sku":"BWCS-LHA500SL-3","price":28.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-LHA500SL-1.webp?v=1779934117","url":"https:\/\/batteryweb.com\/products\/lightspeed-aviation-replacement-battery-37v-1050mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
