Hunting radio battery adapter Lafayette

Getting tired of buying special expensive one-purpose batteries?
Batteries with less power than the ones that you already have at home?

I already changed the cells in the original battery pack a couple of years ago and now it was time again so why don't use something already ready?
Of course if you like you can print a bigger battery pack with the power you like as i will enclose the scad
