These radios are widely used in security, public safety, and commercial field operations where consistent RF output across a full shift matters. Capacity figure is 1600mAh (11.84Wh) — taken from cell-level testing, not the OEM label.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eVX-230 \/ VX-231 \/ VX-234 platform fit:\u003c\/strong\u003e\n    All four models share the same battery bay geometry, gold contact strip layout, and BMS handshake protocol. The FNB-V131Li and FNB-V132Li are electrically identical — the VX-234 uses the V132 designation on its OEM label, but the connector, voltage rail, and BMS communication are the same pack.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this battery through transmit loads matching sustained PTT use on the VX-231 platform. The BMS held the discharge curve cleanly, tripped overcurrent protection at the correct threshold, and recovered without faulting the charger dock.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst insertion on the dock:\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 VX-series dock requires a clean contact cycle to accept the new 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-230 cuts out mid-transmission on a new battery\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eA new Li-ion cell ships at storage voltage — typically 3.6–3.7V per cell, or around 7.2V at the pack level. When PTT is pressed, transmit current spikes sharply. If the pack voltage is already sitting near the BMS low-voltage threshold, that spike can trip the overcurrent or undervoltage cutoff mid-keying. The radio goes silent, then recovers within seconds. The fix is a full charge before the first shift — do not deploy this pack straight from the box.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBar indicator showing one fewer bar than expected after a full charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe VX-series radios use a simple voltage-threshold bar display — each bar corresponds to a voltage window, not a fuel gauge reading. A new cell at its first full charge may settle 50–80mV below a well-conditioned pack at rest, putting it one threshold step lower on the indicator. This is not a fault. After two or three full charge-discharge cycles, resting voltage stabilises and the display reflects the correct state. If the indicator stays low after three cycles, check dock contact voltage with a multimeter — you should read at or above 8.3V at the pack terminals after a complete charge.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426316386394,"sku":"BWCS-FNV131TW-1","price":40.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426316419162,"sku":"BWCS-FNV131TW-2","price":46.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426316451930,"sku":"BWCS-FNV131TW-3","price":51.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-FNV131TW-1.webp?v=1779930632","url":"https:\/\/batteryweb.com\/products\/vertex-standard-vx-230-replacement-battery-74v-1600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
