WOH! Some of the newer rigs only use 4 wires for control. My FT90 does and it would be interesting if the control head could be separated that far from the base unit and still work. I'm assuming you would have to use shielded 4 conductor cable. Wonder what the manufacturer say about running that sort of distance?  Art

Check out your local Radio Shack for R/C car racing batteries.  They come in several different voltages and sizes. I use several of the 9.6 volt NiMH racing car batteries to power my VX5.  They come with a wall wart charger that shuts off automatically and amp hour rating is 1460 mAhr. All you have to do is make an adapter from the connector on the battery to the external power plug of your handheld. I found the mating connectors at a local hobby shop. Don't forget to fuse the adapter cord. I also use a small 10 watt solar panel to top off the batteries once in a while as well as using it to trickle charge a 100 amphr gel cell I picked up at a hamfest for powering the low band rig. (for when the lights really go out.)

The popular 7amphr 12v batteries available for a few bucks at hamfests and are great for emergency power sources for a handheld. They're also used in a lot of the computer back up UPS's.

I also picked up one of those rechargable power centers at a local Walmart sale that included a built in light and 140 watt AC inverter. (for powering the local AC radio or portable TV while waiting for the power to come back on.) It also came with a wall wart charger and cigarette lighter charger cable that can be used to charge the internal 18 amphr gel cell from another DC source such as a car lighter plug or you can turn the cord around and run other equipment from the cigarette lighter plug located on the front panel.

Using my VX5 DC power cord with this unit makes it pretty darned handy when the lights go out and it would probably run it for a couple of days if I needed to.
