It replaces OEM part numbers BP120, BP150, BP180, and BP250. Voltage and cell count match the original pack exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSC140 and SC150 platform fit:\u003c\/strong\u003e\n    Both the SC140 and SC150 variants share the same 4.8V four-cell Ni-MH architecture, connector pinout, and BMS handshake — so one pack covers the full range without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack under simulated PTT load bursts on SC150-series hardware. The BMS handled transmit current spikes without tripping, and the pack held stable voltage through repeated charge-discharge cycles.\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 contact strip with a dry cloth, and reseat firmly. The SC-series charger requires a clean contact cycle to initiate 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 SC140 cuts out mid-transmission on a freshly inserted pack\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells ship at storage voltage — typically around 1.0–1.1V per cell, giving roughly 4.0–4.4V across a four-cell pack. When PTT is pressed, the transmit current spike can pull pack voltage below the radio's undervoltage cutoff threshold before the cells have had a conditioning charge. The radio interprets this as a depleted pack and drops transmission. A single full charge cycle before first use brings each cell above 1.2V and resolves this entirely.\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 SC-series radio reads battery level using a simple voltage-threshold indicator — not a fuel gauge chip. A new Ni-MH pack at storage voltage sits below the threshold for a full-bar reading, so the indicator shows one bar low even though the pack is not faulty. Charge the pack fully in the dock until the LED goes green. After one complete charge, resting voltage climbs to approximately 5.6–5.8V and the indicator will reflect the correct level.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426371731546,"sku":"BWCS-SC150BL-1","price":28.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426371764314,"sku":"BWCS-SC150BL-2","price":32.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426371797082,"sku":"BWCS-SC150BL-3","price":35.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SC150BL_1.webp?v=1779931027","url":"https:\/\/batteryweb.com\/products\/nascar-sc140-replacement-battery-48v-1200mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
