Battery Back Up , External Etc. ?

[KD0CAC]

I did a little searching , but did not see much ?

 

A while back , months or more same thing , found a post about a - clip-on & plug-in external battery and the link back then was not available in the US [ did not come up with todays search ] ?

 

But getting ready for a week to 10 day prospecting trip , so looking again .

My 800 does not have a lot of use , so not worried about battery replacement , just not able to charge from a remote mountain trip .

 

A couple of ideas occurred while searching & reading , needed spec.s for looking or building something ?

 

Will be doing some placer mining in Colorado .
