Both variants share the same battery bay dimensions and BMS interface, so one part number covers the full P30 platform. Capacity is sourced from the product data: 3300mAh (12.71Wh).\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eP30 and P30 PoC platform fit:\u003c\/strong\u003e\n    Both models use the same 3.85V rail, identical connector pinout, and a shared BMS handshake protocol. A single BP3301 pack seats and communicates correctly in either variant 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 a P30 unit. The BMS responded correctly to transmit current spikes, held the protection threshold without nuisance tripping, and accepted a standard Hytera dock charge cycle without fault.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst insertion on the Hytera dock:\u003c\/strong\u003e\n    If the dock LED blinks fault on first seating, remove the pack and wipe the gold contact strip with a dry cloth. The Hytera charging dock requires a clean contact surface to complete the initial BMS handshake — a brief contact contamination is enough to block acceptance.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eP30 cutting out mid-transmission on a new BP3301\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eWhen you press PTT, the P30 draws a sharp current spike to power the RF output stage. A new Li-Polymer cell at storage voltage — typically around 3.7V — sits close to the BMS undervoltage threshold before any load is applied. That spike can push internal resistance high enough that the BMS registers a transient undervoltage and trips the output. Running two or three full charge cycles brings cell voltage and internal resistance to normal operating range, and the cutout stops.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eP30 bar indicator showing one fewer bar than expected on a new pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe P30 uses voltage-threshold bar indicators, not a fuel gauge chip. A new cell shipped at storage voltage reads lower than a fully charged cell, so the radio maps it to a lower bar level even though the pack is not depleted. Charge the BP3301 to full on a Hytera dock — target terminal voltage is approximately 4.35V for this chemistry — and the bar indicator will reflect the correct state on the next power cycle.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426214772826,"sku":"BWCS-HYP300TW-1","price":61.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426214805594,"sku":"BWCS-HYP300TW-2","price":71.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426214838362,"sku":"BWCS-HYP300TW-3","price":80.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HYP300TW-1.webp?v=1779930493","url":"https:\/\/batteryweb.com\/products\/hytera-p30-replacement-battery-385v-3300mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
