Is the CMCF930B compatible with CRAFTSMAN V20 batteries, and what size pack makes the most sense?

Because the CMCF930B is tool-only, it is the better value if you already own a charger and enough V20 batteries.
What do the key specs on the CMCF930B mean in actual use?
The headline numbers are 300 RPM, 420 in-lbs of torque. Brushed motor construction affects efficiency and heat.
How much does the CMCF930B's brushed motor matter to a buyer?
A brushed CMCF930B is the value choice. It can still be the right fit for intermittent jobs, but frequent users usually notice the runtime and performance advantage of brushless alternatives.
What kind of buyer is the CMCF930B aimed at?
The CMCF930B is for someone choosing around its actual numbers and package contents, not just the brand name: CRAFTSMAN V20 Cordless 3/8-Inch Drive Ratchet (Tool Only) with 300 RPM, 420 in-lbs of torque.
