It fits the Kenwood CP-213, ProTalk TK-2200V2P, ProTalk TK-2200V8P, TCP-113, and over 62 additional Kenwood models. The pack slots into the same bay and runs the same 7.4V rail as the original.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCP-213 and TK-2200 series fitment:\u003c\/strong\u003e\n    These models share a common battery bay geometry, contact pin layout, and 7.4V power rail. The BMS handshake protocol is identical across the KNB-14 through KNB-21 family, so one cell design covers all of them without adapter plates or firmware changes.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack on a CP-213 and a TK-2200V2P. The BMS accepted the initial handshake on both docks without fault. Transmit current spikes during PTT were absorbed without triggering overcurrent cutoff at rated output power.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst insertion into the charger dock:\u003c\/strong\u003e\n    If the dock LED flashes fault on first insertion, remove the pack, wipe the gold contact strip with a dry cloth, and reseat it firmly. The Kenwood dock requires a clean contact cycle to register the new BMS before the charge sequence begins — a single reseat usually clears it.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the CP-213 cuts out mid-transmission on a freshly inserted battery\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eNew Li-ion cells ship at storage voltage — typically 3.6–3.7V per cell, or around 7.2V total. When the CP-213 keys up, transmit current can jump sharply. If the cell is still at storage voltage and not yet at a full charge state, the BMS may read that current spike as an overcurrent event and trip. The fix is straightforward: charge the pack fully before the first transmit cycle, not just before the first shift. A rested, fully charged cell handles the PTT inrush without tripping the cutoff.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBar indicator showing one fewer bar than expected after charging completes\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe TK-2200 and CP-213 use a voltage-threshold bar display — each bar maps to a voltage band, not a fuel gauge chip. A new pack fresh from storage may read one bar low even after the dock shows green, because the resting voltage hasn't yet stabilised at the top of the charge curve. Give the pack 15–20 minutes off the charger before checking the indicator. If the bar count still reads low after a full charge cycle and a rest period, measure the pack voltage across the contacts — a healthy fully charged cell should read at or above 8.2V.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426331328602,"sku":"BWCS-KNB150TW-1","price":39.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426331361370,"sku":"BWCS-KNB150TW-2","price":45.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426331394138,"sku":"BWCS-KNB150TW-3","price":50.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-KNB150TW_1.webp?v=1779930721","url":"https:\/\/batteryweb.com\/products\/kenwood-cp-213-replacement-battery-74v-1800mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
