Thank you for your question. Yes, the 4 and 5 ah Lithium batteries like the BAT620 and BAT621 will work with the DDB180 drill/driver. The drill will accept all generations and ah of our 18v Lithium batteries.

Not sure how well it works for drills and other small power tools, but is working well for our small mobile robot. Having a second battery on the charger whole running allows us to demo our vehicle and quickly change batteries without using large, more cumbersome batteries.
