If you go Li-ion, voltage is not going to matter. All of the Li=ion

18 volt Li-ion is probably lighter in weight than a 12 bolt non
Li-ion.

Only if you go with the small LiON batteries. Full sized battery - no way,

OK, for the record, A Festool 14.4v Li-Ion 3 amp battery weighs 19.8 oz.

A Makita 12 volt 2.6 amp Hi MH weighs 24.5 oz.

A Bosch, half size in appearance, 18 volt Li-ion 1.3 amp battery weighs
11.7 oz.

So the half size Bosch is approximately 60% the weight of the full size
Festool battery and the full size Festool battery is 80% the weight of
the similar sized Ni MH Makita 12 volt battery.


FWIW the Festool battery appears to be equal in size if not slightly
smaller than the Makita battery. The Festool battery has no stem that
engages the handle of the drill as the Makita battery has.
