If you want a compact battery that packs a punch, it's this or the 4ah Powerpack. Better deals have existed on the Powerpack 4ah. This isn't a great deal but this isn't a terrible deal if you want the Powerstack tech. I don't often see deals on these by themselves. Personally, I would lean towards the Powerpack 4ah.
If you're a fudd who subscribes to the 2017 mantra of $10 per amp hour, move along and get some of the standard 5ah batteries when they're $50 each. They'll be perfectly fine for most homeowners, and we need you to help move that inventory. If you have high-peak power demands from your tools, you're going to need to pay more per amp hour for stacked lithium or tabless battery tech.
