It replaces OEM part numbers FNB-V47, FNB-V47IS, FNB-47, FNB-47H, FNB-V49, and FNB-V49H. Capacity is 2000mAh (14.4Wh) — matching the original specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eVX-10 \/ FT-series platform fit:\u003c\/strong\u003e\n    These models share the same battery bay dimensions, contact pin layout, and 7.2V voltage rail. The BMS handshake is consistent across this platform, so the pack seats and charges the same way on each radio body in the series.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through transmit loads on the VX-10 platform. The BMS handled the PTT current spike without triggering overcurrent cutoff, and voltage held within the expected operating window under sustained RF output.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst insertion on the Yaesu charger dock:\u003c\/strong\u003e\n    If the dock shows a fault indicator on first insertion, remove the pack, wipe the gold contact strip with a dry cloth, and reseat firmly. The Yaesu charger requires a clean contact cycle to complete the initial 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 VX-10 drops to reduced TX power mid-shift on a new FNB-V47\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells ship at partial storage voltage, typically around 6.0–6.4V across a 6-cell pack. The VX-10 firmware monitors the voltage rail during transmit and steps down output power when voltage sags below the RF stage threshold. This is not a fault in the battery — it is the radio protecting its PA stage. A full charge cycle before putting the radio into service brings cell voltage up to the 7.2V nominal rail and eliminates the sag under transmit load.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBar indicator showing one fewer bar than expected after inserting the FNB-V47\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe VX-10 uses a voltage-threshold bar indicator, not a capacity-counting circuit. A new pack at storage voltage reads lower than a fully charged pack, so the radio displays fewer bars even though the battery is not defective. Put the pack through one complete charge on the Yaesu dock. Once the pack reaches full charge voltage, the bar display will reflect the actual state. Do not judge capacity from the first reading after insertion.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426350104666,"sku":"BWCS-FNB47TW-1","price":53.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426350137434,"sku":"BWCS-FNB47TW-2","price":62.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426350170202,"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\/yaesu-vx-10-replacement-battery-72v-2000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
