I have an '897 here, and I've been looking through the manual. Do you have some reason to think that running with the internal battery connection takes lower power?

I don't see that, though it may be an undocumented feature. (There is a "battery" indicator on the LCD, so the rig does know that it's on batteries.) I suspect it will work the same if you connect the main DC power input to your batteries. If you want to save battery power for longer life, you have to reduce the transmit power level using the normal menu settings.

The Yaesu internal batteries make a nice package, but they seem to be rather expensive compared to standard batteries.

You can connect as many amp-hours capacity as you like. It's just a question of battery lifetime per charge, vs weight. The radio only cares about the voltage.

Thank you. You are right, reducing the power would have the same result. I was just trying something different.

I am trying to get away with using an external cheaper battery, to be part of a go box I am building.

My box is going to be capable of running on Solar or AC (power supply). As soon as I figure out how to connect the solar controller and the PWRgate PG-40s to the same battery.

I wanted to eliminate the power supply out of the equation. Thanks to all the responses.

Hello, I would like to take advantage of the low power consumption of the Yaesu FT-897 while using batteries. But, do not want to use the internal batteries. In other words. I like to power the radio through the Batt. plug and not through the 13.5v power connector.

Could I make a power cable to connect to an outside battery, such as seal lead?

Would a different Amp Hour rating would damage the radio?

Thank you.
