New battery power for my FT-817

I have long wanted/needed to upgrade my battery power for my Yaesu FT-817. The prompt came when the internal battery died. My choice was the kit put out by Windcamp; a 3000mAh internal LiPo battery and new battery compartment lid for the radio that comes fitted with a PCB and charging circuitry that allows the supplied mains charger to charge the battery while inside the radio.

The parcel arrived from China beautifully packed. The battery and the new replacement lid came packaged in very nice plastic cases, which, together with the instructions and charger, all fitted into a compact cardboard box for shipping.

The contents of the parcel.

After extracting the individual components from their packaging, it was time to think about installing the battery into the radio.

It is a tight fit but the components plugged together as intended. Note the PCB on the underside of the new lid.

When the battery and associated wiring was all nice and snugly fitted, I popped the lid closed and got ready to charge the new LiPo battery.

The new lid in place and ready for charging.

The charger has a double-coloured LED to indicate the state of the charge: red for charging and green for a completed charge. The initial charge takes around 5 hours to accomplish.

According to the supplied documentation, the rated voltage of the battery is 11.1V, with the output voltage range stated as between 9 and 12.6V. The maximum output current is 4A.

Now to test it in the field.
