A new pack coming off its first charge may read slightly below the top threshold if the charger terminated early due to a cell impedance mismatch with the dock's charge algorithm. Run one complete discharge-and-recharge cycle on the dock to let the BMS settle. After that second charge, the pack typically reads the correct number of bars. If it still shows short, check the dock contacts at 8.2–8.4V open-circuit — that is the expected fully charged voltage for a 7.4V Li-ion pack.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43303974830170,"sku":"BWCS-HYD788TC-1","price":59.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43303974862938,"sku":"BWCS-HYD788TC-2","price":70.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43303974895706,"sku":"BWCS-HYD788TC-3","price":77.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HYD788TC_1.webp?v=1777520716"},{"product_id":"hyt-dmr-pd-702-replacement-battery-74v-2600mah-li-ion","title":"HYT BL2006 DMR PD-702 Replacement Battery 7.4V 2600mAh","description":"\u003cdiv class=\"bpw-desc\"\u003e\n  \u003ch2 class=\"bpw-desc-h2\"\u003eHYT DMR PD-702 \/ PD-782 Series — 7.4V Li-ion Replacement Battery (BL2006)\u003c\/h2\u003e\n\n  \u003cp class=\"bpw-desc-lead\"\u003eThis is a 7.4V, 2600mAh Li-ion battery for the HYT DMR PD-702, DMR PD-782, PD70X, and PD70XG series digital mobile radios.

The BS-81G responds to a voltage sag by stepping down transmit power to protect the circuit. This is not a faulty battery — it is the radio managing a real voltage drop. Check resting voltage after the radio cools; if it recovers above 3.7V, impedance is the cause.

The pack fits directly into Icom's standard battery bay and connects via the same multi-pin contact strip used across the BP-230 family.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eIC-A14 and IC-F14 platform fit:\u003c\/strong\u003e\n    Icom built the IC-A14 aviation radio and the IC-F14 land mobile series around the same 7.4V battery bay, contact layout, and BMS handshake protocol — so one pack covers both lines without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through transmit-cycle testing on the IC-F14 platform. The BMS held voltage steady through repeated PTT events, and the charger dock accepted the BMS handshake without a fault LED on first insertion.\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 initial seating, remove the pack, wipe the gold contact strip with a dry cloth, and reseat firmly. The Icom 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 IC-A14 drops TX power mid-transmission on a new BP-230 replacement\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eA new cell ships at storage voltage — typically around 3.7V per cell, not the 4.2V per cell seen after a full charge. Under the sustained RF output of a VHF transmission, the IC-A14 draws peak current that causes the pack to sag below the radio's TX power threshold before it sees a true low-battery condition. The radio interprets this voltage sag as insufficient headroom and steps down transmit power to protect the circuit. A full charge cycle before first use brings both cells to 4.2V and eliminates this sag behaviour entirely.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBar indicator reading one fewer bar than expected after inserting a fully charged pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe IC-A14 and IC-F14 use a voltage-threshold bar indicator — each bar corresponds to a voltage band, not a tracked charge percentage. A new pack that was charged in a different dock may have a slightly lower resting voltage due to surface charge settling, which pushes the reading into the next band down. Let the radio sit powered on for two to three minutes without transmitting; the resting voltage stabilises and the bar indicator corrects itself. If the indicator still reads low after settling, confirm pack voltage directly — a fully charged 7.4V Li-ion pack should measure between 8.2V and 8.4V at rest.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426196881498,"sku":"BWCS-ICM234TW-1","price":80.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426196914266,"sku":"BWCS-ICM234TW-2","price":94.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426196947034,"sku":"BWCS-ICM234TW-3","price":105.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ICM234TW-1.webp?v=1779930436"}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/collections\/BW-CS-VTR610TH_6.webp?v=1780022252","url":"https:\/\/batteryweb.com\/collections\/two-way-radio-1.oembed?page=3","provider":"BatteryWeb","version":"1.0","type":"link"}
