It matches the OEM voltage rail and connector footprint for both models. Capacity is 3400mAh (25.16Wh) — use the product data figure, not the depleted OEM reading from a worn pack.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eEP8100 and EP8000 platform:\u003c\/strong\u003e\n    Both models share the same battery bay dimensions, connector pinout, and 7.4V nominal rail. The BMS on each accepts the same charge profile, so one replacement cell covers both devices without any hardware modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through PTT transmit loads and monitored the BMS response to sustained RF output. The overcurrent threshold held correctly and the protection circuit did not trip under normal transmit bursts.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-insertion contact check:\u003c\/strong\u003e\n    If the charger dock shows a fault LED on first insertion, remove the battery, wipe the gold contact strip with a dry cloth, and reseat firmly. The EP8000\/EP8100 platform requires a clean contact cycle to complete 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 EP8100 cuts out mid-transmission on a new battery\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eA new cell ships at storage voltage — typically 3.7–3.8V per cell, not full charge. When PTT is pressed, transmit current draw spikes sharply. If the cell voltage is already at the low end of storage range, that spike can push the BMS into an overcurrent trip, killing TX mid-keying. Charge the pack fully in the dock before first field use. A full charge brings each cell above 4.1V and gives the BMS headroom to handle the transmit surge without tripping.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBar indicator showing one fewer bar than expected on a fresh pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe EP8100 uses a simple voltage-threshold bar display — each bar maps to a voltage band, not a percentage from a fuel gauge chip. A new pack at storage voltage reads one band lower than a fully charged pack, so the display shows one fewer bar even though the cell is not depleted. This is not a faulty battery. Run the pack through a full charge cycle in the dock and the bar indicator will step up to reflect the correct resting voltage above 8.2V.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426305441882,"sku":"BWCS-EXP810TW-1","price":47.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426305474650,"sku":"BWCS-EXP810TW-2","price":54.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426305507418,"sku":"BWCS-EXP810TW-3","price":60.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-EXP810TW-1.webp?v=1779930583","url":"https:\/\/batteryweb.com\/products\/diquea-ep8100-replacement-battery-74v-3400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
