I bought a combo drill & driver kit recently and I really love it, but it came with "XC" batteries that are 4Ah. I went to buy one of the slim packs because sometimes the large batteries are just too heavy for what I am doing - but even the slim packs are $70!
The kit I bought came with a drill and driver and 2 XC batteries. Each XC battery costs $130 retail, but I only paid $390 for the kit. At retail value that means the drill and driver and charger were only 130. (Drill and driver and charger are same price as one battery?)
The math just doesn't work out. So, why are the batteries so expensive!?
