You're not going to find LiPos in stores other than hobby shops. And probably not IMRs, unless you go to a camera shop. They are both considered "special purpose" batteries.

Now about those IKEA  batteries. They are traditional old-school Nimh (Nickel-metal hydride) batteries. They will definitely work in Nerf blasters, and over a relatively short period of time they'll pay for themselves. They're also very safe and there's no special handling.

But here's the downside. Those LADDA batteries are only 1.2 volts. That's just 80% of the power of grocery-store batteries. At 2450 mAh the current is actually pretty good, but it's the voltage that makes Nerf blasters work better, faster, and shoot farther. You might be saving some coin, but your buddy with no-name alkaline batteries is going to outshoot you.

Nimh batteries also have a "". It's not technically accurate, but that's what they call it. The more you recharge them, the quicker they discharge. Toward the end of their life they take all night to charge but only provide power for a few minutes (or seconds).

Bottom line, Nimh is being replaced by various Lithium chemistries because they don't have all those problems that make Nimh batteries so crappy. For less money you could get a pair of IMRs on Amazon that would really make your Nerf blaster hum.
