It matches the original connector layout and BMS handshake protocol used across the G2 platform. Capacity is 2000mAh (9.6Wh) — identical to the factory specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eG2 platform compatibility:\u003c\/strong\u003e\n    The G2 series and its variants share the same 4.8V voltage rail, physical connector, and BMS communication sequence. A single pack covers the full range because the charging dock negotiates with the pack over the same contact strip regardless of the specific variant suffix.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through transmit loads on the G2 platform and confirmed the BMS holds voltage through sustained PTT press without tripping overcurrent protection. The pack accepted a full charge cycle without fault LED on the dock.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst insertion contact check:\u003c\/strong\u003e\n    If the dock shows a fault LED on first insertion, remove the pack, wipe the gold contact strip with a dry cloth, and reseat firmly. The G2 dock requires a clean contact cycle to complete the BMS handshake before charging begins — this is not a defect.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the G2 drops to reduced TX power mid-shift on an ageing Ni-MH pack\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells develop internal impedance over repeated cycles. Under the current spike of a sustained PTT press, a high-impedance cell sags below the radio's minimum operating voltage threshold. The G2 firmware interprets this as a low-battery condition and steps down transmit power to protect the RF stage. Replacing the pack restores the voltage headroom the radio needs to sustain full TX output through a shift.\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\"\u003eNew Ni-MH cells ship at storage voltage, not full charge voltage — typically 1.2V per cell, which reads lower than a freshly charged cell at 1.4V. The G2 bar indicator uses simple voltage thresholds, so a new pack at storage voltage will display one bar fewer than its actual capacity warrants. Run a full charge cycle before judging the pack's state. After one complete charge, the bar indicator will reflect the true cell voltage and the reading will correct itself.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426353217626,"sku":"BWCS-ETH736TW-1","price":64.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426353250394,"sku":"BWCS-ETH736TW-2","price":75.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426353283162,"sku":"BWCS-ETH736TW-3","price":84.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ETH736TW-1.webp?v=1779930808","url":"https:\/\/batteryweb.com\/products\/eads-g2-replacement-battery-48v-2000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
