It matches the OEM voltage rail and connector footprint on both models. Part numbers HR7742AAA02 and HR7742AAB02 are cross-compatible — same cell configuration, same BMS pinout.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eTPH700 and P3G platform fit:\u003c\/strong\u003e\n    Both models share the same battery bay geometry, contact strip layout, and 7.4V nominal rail. The BMS handshake protocol is identical across the two, so one pack covers either radio without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through full charge and discharge on the TPH700 dock. The BMS held cutoff at the correct low-voltage threshold and accepted charge on the first insertion without a fault condition.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eContact strip seating on first dock insertion:\u003c\/strong\u003e\n    If the charger shows a fault LED on first use, remove the pack, wipe the gold contact strip with a dry cloth, and reseat firmly. The TPH700 dock 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 TPH700 cuts out mid-transmission on a new battery\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eTransmit current on the TPH700 spikes sharply the moment PTT is pressed. If the pack is at storage voltage — typically 3.7V per cell — rather than a full charge, that surge can pull cell voltage below the BMS overcurrent threshold in under a second. The BMS trips, the radio cuts audio, and it recovers within moments. This is not a faulty pack — it is a cell that has not yet been brought to operational voltage. Charge the battery fully before the first field use to avoid mid-transmission dropout.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBar indicator showing one fewer bar than expected on a new pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe TPH700 uses a simple voltage-threshold bar indicator — each bar maps to a voltage band, not a percentage algorithm. A new pack shipped at storage voltage reads in the lower bands immediately after insertion, which looks like a weak or partially charged battery. This is normal. After a full charge cycle, cell voltage rises into the correct band and the indicator reflects actual capacity. If bars remain low after a complete charge, check that the dock contacts are clean and the charge cycle completed without interruption.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426338963546,"sku":"BWCS-ETH700TX-1","price":66.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426338996314,"sku":"BWCS-ETH700TX-2","price":78.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426339029082,"sku":"BWCS-ETH700TX-3","price":87.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ETH700TX-1.webp?v=1779930720","url":"https:\/\/batteryweb.com\/products\/eads-tph700-replacement-battery-74v-2300mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
