Hello Leigh,
It is nothing complicated. I measured the size of battery mount of KBT2 and
bought 3 retangular shape Li-po cells to fill up the mount.
For charging circuity, I just used what Don W3FPR mentioned in his webpage. Of
course, the best way to charge the Li-Po cells is to use an intelligent balance
charger which usually can be found in radio control players.
The danger of using Li-po cells is usually related to overcharging or over
discharging. In any event, charge the Li-po cells with a intelligent charger
with both voltage and current control.
cheers,
Johnny VR2XMC

Johnny,
Do you have pictures posted? I remember when you started this project and
I'd like to see how it worked out.
Presonally I lean more toward LiFePO4; although they have a lower energy
density than the Li-Po (though higher power density) they reportedly are
safer in conditions of over/under charge and mechanical stress.
