I have an ancient 18v one of these - uses Ni-Cads. All the batteries for

adaptor, so handy for the odd awkward space.

There's plenty room inside a battery case for 18v worth of 18650 Li-Ion,
and I do realise I'd need to mod the charger too.

Dedicated right angle cordless drills seem to be an arm and a leg -
unless
someone knows different?

Anyone done this sort of mod?

One option would be to put in NiMH which are still available. Some
chargers (e.g. my Makita one) are compatible. That said, I've got a
NiCad Ryobi drill plus angle drill plus all the bits in the bag of
"metal" scrap ready to go to the tip because ICBA to re-cell it.

Even the Aldi/Lidl LiIon drills have more oomph than the old NiCad ones.

The cost of a new Li-ion screwdriver was less than the cost of
re-celling my ancient Makita NiCd one.

The batteries are the main part of the cost in these things

You could build an 18v Lion pack if you were prepared to buy a separate
charger

Or at least a 16.8V (4s) or 21V (5s) one!
