Pofung P15UV Replacement Battery 7.4V 2000mAh

Pofung P15UV — 7.4V Li-ion Replacement Battery

This 7.4V 2000mAh Li-ion battery replaces the original pack in the Pofung P15UV dual-band handheld transceiver. It matches the stock voltage rail and physical form factor of the P15UV battery compartment. Capacity is rated at 2000mAh (14.8Wh) — identical to the factory specification.

• P15UV platform fit: The P15UV runs a 7.4V two-cell Li-ion configuration with a specific contact layout at the base of the radio. This replacement matches that layout and the BMS handshake the radio expects before it powers the RF board.
• Bench tested on actual hardware: We ran this pack through full charge and PTT transmit cycles on the P15UV. The BMS held through repeated transmit current spikes without tripping, and the radio's bar indicator responded correctly at each charge threshold.
• Contact seating on first insertion: If the P15UV charger dock shows a fault or blink on first insertion, remove the battery, wipe the gold contact strip with a dry cloth, and reseat firmly. The dock requires a clean contact cycle to accept the new BMS before charging begins.

Why the P15UV cuts out mid-transmission on a new battery

The P15UV draws a sharp current spike the moment PTT is pressed — the RF amplifier stage demands significantly more current than standby draw. If the battery BMS interprets that spike as an overcurrent fault, it trips and cuts power to the radio mid-transmission. A new cell at storage voltage (typically 3.7–3.8V per cell) has slightly elevated internal impedance, which makes this trip more likely on the first few cycles. Charge the pack fully to 8.4V before putting it into transmit use and the BMS will settle after two or three full cycles.

P15UV showing one fewer bar than expected after installing a new pack

The P15UV uses voltage-threshold bar indicators — each bar corresponds to a specific voltage band, not a fuel gauge calculation. A new battery ships at storage voltage, around 3.7V per cell, which sits in the lower threshold band and triggers fewer bars on the display. This is not a fault with the cell. Charge the pack fully to 8.4V and the bar indicator will move to its correct position.
