Direct replacement for Yaesu radios

The Estry VX-177 is a nickel-metal-hydride pack rated at 7.2 volts and 1800 milliampere-hours. It matches the original FNB-64, FNB-64H, FNB-83, FNB-83H, FNB-V57 and FNB-V57H part numbers. The cell is built to the same dimensions and electrical specification as the factory unit.

Chemistry and voltage define the limits

Nickel-metal-hydride chemistry delivers 7.2 volts nominal and 12.96 watt-hours total energy. Capacity falls in cold weather and self-discharge rises during long storage. The pack has no built-in fuel gauge, so remaining run time must be estimated from voltage or usage history.

Simple slide-in install, watch polarity

The battery slides into the radio compartment and locks with the existing latch. No tools are required. The most common error is forcing the pack in upside-down, which can damage the connector pins. Confirm the model list and part number before fitting.

Questions about this item

Which compatible model or part number should I pick for my radio?

Match your radio to the list: VX-177, VXA-120 Pro II, VX-414, VX-410, FT-277R, VX-800U, VX-110, VX-120, FT-250R, VX-210A, FT-60R, VX-160, VX-417, FT-270E or part numbers FNB-64H, FNB-V57, FNB-83, FNB-83H, FNB-64, FNB-V57H.

What does the 1800mAh rating mean for actual operating time?

The pack stores 12.96Wh at 7.2V; run time depends on your radio's transmit power and receive current, so divide 12.96Wh by the radio's average watt draw to estimate hours.

Does the 7.2V Ni-MH chemistry limit charging or use in any way?

It requires a charger designed for 7.2V Ni-MH packs; the built-in protection guards against overcharge, over-discharge, over-voltage and short circuits.
