bah, you're right, they are infact Li-ion.... but everyone refers to them as lipo. Man, I fell into that trap too.

From my research, Li-ion and Li-poly have about the same if not the same charging characterisitcs. The difference being that li-po use a solid electrolyte. I have charged these batteries with my apache without a problem.

Well, I take that back.... it seems to charge my 18650 size batteries, but it never turns green. It does say that it is capable of packs up to 1500mah and these batteries are 1600mah.

I'm not sure why that is a factor personally... if a charger can supply a voltage higher than the batteries, it should still charge no matter what the capacity. Maybe Azimov can answer that.

As far as not getting AAA's. AA size work on all the cars and have larger capacity. I got AA size for 3.30 each as stated and the AAA's would have been like $2.80 each or something. A lot came down to price. I've put some AA's on my evo car too.... about similar clearance without the battery holder on.

I also wanted AA's for my super slicks truck and the 1/24 black NSX i'm building.
