It matches the original voltage rail and connector format, and slots directly into the radio body without modification. OEM part numbers HR7742AAA02 and HR7742AAB02 are both covered by this replacement.\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 layout, and 7.4V nominal voltage requirement. The BMS in this pack is tuned to the same communication handshake the dock and radio expect on power-up.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through full charge and discharge cycles on the TPH700 platform. The BMS tripped correctly at low-voltage cutoff and accepted recharge without fault flags on the dock LED.\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 when you first seat this battery, 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 will begin.\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  \u003cp class=\"bpw-desc-p\"\u003eWhen you key PTT, the radio draws a sharp current spike to power the RF transmit stage. If the BMS detects this spike as overcurrent — which can happen in the first few cycles before the cells settle — it trips the protection circuit and kills output. This is not a faulty pack; it is the BMS acting on an unfamiliar impedance profile. Run two or three full charge and discharge cycles to let the cells stabilise, and the BMS will stop tripping on transmit current.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBar indicator showing one fewer bar than expected after fitting a new pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNew Li-ion cells ship at storage voltage — typically around 3.7V per cell, not the 4.2V of a full charge. The TPH700 reads voltage thresholds to set the bar count, so a pack at storage voltage will show one or two bars even though the cells are healthy. Charge the battery to full in the dock before the first use. Once the pack reaches full charge voltage, the indicator will read correctly.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426339323994,"sku":"BWCS-ETH700TW-1","price":44.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426339356762,"sku":"BWCS-ETH700TW-2","price":51.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426339389530,"sku":"BWCS-ETH700TW-3","price":57.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ETH700TW-1.webp?v=1779930720","url":"https:\/\/batteryweb.com\/products\/eads-tph700-replacement-battery-74v-1800mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
