Looking for suggestions to buy cordless drills (for contractors)

As a contractor, what sort of things you generally look for in a cordless drill? What will be the factors to pick the cordless drill in this case? Would greatly appreciate any advice from you guys…Thanks

Just out of curiosity, are you looking to buy some drills yourself? Or do you want to sell them to contractors? Or are you helping to manufacture some drills? Or are you working for one of those garbagey “review” sites that just retstate the manufacturer’s specs that are propogating by the dozen?
