It matches the original voltage rail, cell chemistry, and BMS communication profile required by both models. Capacity figure is taken from the product specification — 17.76Wh at 2400mAh.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eEP8000 and EP8100 compatibility:\u003c\/strong\u003e\n    Both models run the same 7.4V nominal rail and use an identical connector and BMS handshake sequence. A single cell platform covers both, which is why EB242L and EB342L are listed as cross-compatible part numbers across the EP8000 and EP8100 lines.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through charge and discharge on the EP8000 dock. The BMS triggered protection at the correct undervoltage threshold and accepted the charger handshake without fault LEDs on first and repeat insertions.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst insertion on the EP8000 dock:\u003c\/strong\u003e\n    If the dock shows a fault LED on first seating, remove the pack and wipe the gold contact strip with a dry cloth before reseating. The EP8000 dock requires a clean contact surface to complete the BMS handshake — an oxidised or dust-covered strip will block the initial charge acceptance cycle.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eEP8000 radio cutting out mid-transmission on a new battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003ePressing PTT draws a sharp current spike — often 1.5 to 2 times the standby draw — as the transmit circuit activates. A new cell shipped at storage voltage (typically 3.6–3.7V per cell) has less headroom to absorb that spike than a fully charged cell. The BMS reads the sudden voltage sag as an overcurrent event and trips the protection circuit, dropping the radio off mid-transmission. Charge the pack fully to 8.4V before putting it into service — that single step resolves the majority of PTT cutout reports on new batteries.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBar indicator showing one fewer bar than expected after inserting a new pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe EP8000 reads battery level from voltage thresholds, not a fuel gauge chip. A new cell arrives at storage voltage — around 3.6–3.7V per cell — so the pack reads below the top-bar threshold when first inserted. This is normal cell storage practice, not a capacity defect. Run a full charge cycle first; once the pack reaches 8.4V, the bar indicator will reflect the actual charge state correctly.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426305048666,"sku":"BWCS-EXP800TW-1","price":43.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426305081434,"sku":"BWCS-EXP800TW-2","price":50.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426305114202,"sku":"BWCS-EXP800TW-3","price":55.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-EXP800TW-1.webp?v=1779930583","url":"https:\/\/batteryweb.com\/products\/excera-ep8000-replacement-battery-74v-2400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
