It replaces OEM part numbers FNB-V47, FNB-V47IS, FNB-47, FNB-47H, FNB-V49, and FNB-V49H. Drop the old pack out, slide this one in — the connector and latch points are identical to the original.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eVX-10 and FT-series compatibility:\u003c\/strong\u003e\n    These radios share the same battery bay geometry, contact layout, and 7.2V voltage rail across the VX-10, FT-10R, FT-40R, and FT-50R platforms. The BMS in this pack is configured to communicate cleanly with the charge dock and radio firmware on all listed models.\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 PTT load pulls on a VX-10. The BMS held steady through transmit current spikes without tripping, and the pack reached rated 2000mAh capacity within the first three charge cycles.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst insertion contact cycle:\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 Vertex Standard dock requires a clean contact surface to complete the BMS handshake before it will begin charging.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the VX-10 cuts out mid-transmission on a freshly installed pack\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells ship at storage voltage — typically 6.0–6.4V across a 7.2V pack — not at full charge. When you key up on a partially charged pack, the transmit current draw pulls the cell voltage down fast. The BMS reads this as an undervoltage condition and interrupts output to protect the cells. This is not a fault with the pack — it is the BMS doing exactly what it should. Charge the pack fully before the first transmission-heavy shift, and the cutouts will stop.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBar indicator showing one fewer bar than expected after charging\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe VX-10 and FT-series radios read battery level using simple voltage thresholds — there is no fuel gauge chip recalibrating to the new pack. A new Ni-MH cell fresh off the charger may sit at 7.3–7.4V rather than the 7.6V+ that maps to a full-bar reading on the radio's display. Run one complete discharge-and-recharge cycle in the charger dock and the resting voltage will stabilise above the top threshold. After that cycle, the bar indicator will read accurately.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426350268506,"sku":"BWCS-FNB47TW-1","price":53.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426350301274,"sku":"BWCS-FNB47TW-2","price":62.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426350334042,"sku":"BWCS-FNB47TW-3","price":69.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-FNB47TW-1.webp?v=1779930808","url":"https:\/\/batteryweb.com\/products\/vertex-standard-vx-10-replacement-battery-72v-2000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
