[Elecraft] Internal LiFePo4 for KX3

[Ignacy]

I was thinking about the same in order not to carry the external battery.

The only workable way IMHO would be to:
1. Remove the current battery enclosure 
2. Fit 4 polymer Li-Ion , e.g., 2.5A like at the bottom.
3. Connect directly to power inputs, perhaps with a resettable fuse
4. Charge with 2A charger to 15.5-16V (16.8V charger with 1-2 diodes). 

I would not bother fitting LiFePO3 internally as they are bigger and store
less power.

I did a similar thing with K2, and it toured the world without problems.
Great convenience of no extra battery and fast charging.
