Replacement battery for YAESU FT-817

Product Information

First, because the cell is LIPO, it has a separate charger and a separate charge power input, and the manual rightfully strongly advises against using the NiMH charger. Instead of using a 4S-pack for a FT-857D or similiar "big" TRX, I would rather go with a LiFePo4 (please check above) then. Whilst some allowance must be made for the FT-817's small size and portability, especially with regard to ergonomics, several of these criticisms could have been averted using existing technology.

A simple modification to the FT-817/FT-818's rear panel can reduce stress on its DC power connector. SLAB, this battery saves about 2/3 of the weight and delivers more current, as it has a way flatter discharging curve.

This radio is designed for use either from an external DC source or internal batteries and provides up to 5 watts of power output when on external DC power.

Operating the amateur bands from a quiet spot is a treat but don't overlook the rest of the spectrum either.

Several small portable antennas are now available which allow you to easily get the FT-817 on the air out in the field. This radio comes with: MH-31 A8J hand mic, FBA-28 battery case (8 x AA), YHA-63 Whip antenna for 50/144/430 MHz, E-DC6 DC cable and shoulder strap.
