The 18v makita is great. Loads of power. The 3ah battery gives plenty of run time and charges in 20 mins.
Check that the makita stuff is LXT though – there are very similar looking drills by Makita with lower capacity, slower charging batteries, and they’re incompatible with the rest of makita’s 18v range of tools , batteries and chargers.
Do you want a few smaller ones that charge quickly, or two larger ones
With makita stuff 3ah batteries seem to be the sweet spot between charge time and run time, charge very quickly and give a decent work time for drilling and driving. Larger capacity ones take quite a bit longer to charge but are a better choice if you’re going to be away from the mains all day. The bigger capacity batteries also pay dividends more if you also use them for sawing or angle grinding.
For reasons I don’t understand (quarks or something) anything smaller than 3amp hr gets you a physically smaller, lighter battery, but anything larger capacity (4 and 5amp hr) is the same size and same weight.
