It uses OEM part number B-50C and slots directly into the battery bay on both models. Voltage and cell format match the original pack specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eB01 and B02 compatibility:\u003c\/strong\u003e\n    Both radios run on the same 3.7V single-cell platform and share the B-50C form factor — same connector pinout, same BMS handshake voltage window, same physical envelope at 52.30 × 40.00 × 10.10mm.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through transmit and standby loads. The BMS held stable across repeated PTT events, and the protection circuit tripped correctly at the overcurrent threshold — no false lockout during normal TX bursts.\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 on first insertion, remove the pack, wipe the gold contact strip with a dry cloth, and reseat firmly. The B01 dock requires a clean contact surface to complete the BMS handshake before it begins the charge cycle.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the B01 cuts out mid-transmission on a freshly inserted B-50C pack\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eA new cell ships at storage voltage — typically around 3.6V to 3.7V, not at a full charge. When PTT is pressed, transmit current spikes sharply. If the cell is at storage voltage and the BMS sees that spike pull the cell below its undervoltage cutoff threshold, it trips and drops the radio. This is not a faulty pack — it is the BMS doing exactly what it should. Run the pack through one full charge cycle before heavy use and the issue will not repeat.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBar indicator showing one fewer bar than expected after fitting a new B-50C\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe B01 and B02 use a simple voltage-threshold bar indicator — each bar maps to a voltage band, not a fuel gauge chip. A new pack at storage voltage reads lower than a fully charged cell, so the radio displays one bar short. This is not a capacity problem. Charge the pack fully and the indicator will step up to the correct bar level — confirming the cell is sitting at or above the top voltage threshold.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426249769050,"sku":"BWCS-NSR200TW-1","price":47.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426249801818,"sku":"BWCS-NSR200TW-2","price":56.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426249834586,"sku":"BWCS-NSR200TW-3","price":62.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-NSR200TW-1.webp?v=1779930523","url":"https:\/\/batteryweb.com\/products\/inrico-b01-replacement-battery-37v-1700mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
