About this replacement
Icom IC-E85 / IC-F50 Series — 7.2V Li-ion Replacement Battery (BP-227Li)
This 7.2V 1800mAh lithium-ion battery replaces the BP-227Li and related OEM packs across the Icom IC-E85, IC-F50, IC-F51, and fourteen additional compatible handhelds. It slots into the standard Icom battery bay and connects via the same gold contact strip as the original. Voltage and cell count match the OEM spec exactly.
- IC-E85 / IC-F50 platform fit: These handhelds share a common battery bay geometry, contact layout, and BMS handshake protocol. One pack covers the full series because Icom standardised the connector and voltage rail across this product generation.
- Bench tested on actual hardware: We ran this pack through transmit-cycle loads on the IC-F50 platform. The BMS handled repeated PTT current spikes without tripping, and the dock accepted the charge handshake on first insertion after a contact wipe.
- First-insertion contact cycle: 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 charging begins.
Why the IC-E85 cuts out mid-transmission on a new BP-227Li pack
New lithium-ion cells ship at storage voltage — typically 3.6–3.7V per cell — not at full charge. When you key up on the IC-E85, transmit current can hit 1.5A or higher. If the pack hasn't completed a full charge cycle first, that draw can push cell voltage below the BMS undervoltage threshold and trigger a protective cutoff. The radio goes silent, but the pack is not faulty. Charge the battery fully before first transmit use to bring cells to 4.1–4.2V per cell and prevent BMS cutoff under TX load.
Bar indicator showing one fewer bar than expected after fitting this pack
The IC-E85 uses a voltage-threshold bar indicator — it reads pack voltage and maps it to a bar count. A new pack at storage voltage will sit at roughly 7.2–7.4V total, which the radio reads as mid-charge rather than full. This is not a capacity fault or a cell mismatch. Run one full charge cycle in the Icom dock until the charge LED goes green, then reinsert the pack. The bar indicator will reflect the correct fully charged voltage of approximately 8.2–8.4V.
