Lipo vs. Life(A123)

[Sammus]

I've heard and read in several places that DeWalt packs don't use A123 cells anymore because they didnt need the enormous discharge rate or the price tag that comes with it (but I haven't been willing to test these claims). I would recommend you buy the cells from an rc store that sells them (aircraft-world, hobbycity, tanicpacks are 3 I know of).

When I got my cells from h-c they had solder tabs welded to them which made pack construction a breeze. From a-w they didnt, and I bought battery bars. Assembly was more tricky but still wasn't too bad. I did have to buy a much more powerful (80W) iron and be careful not to overheat the cells. Something to keep in mind.

And yes I agree with pimp, size weight and fitmentwise, lipo wins. I just love the 15min charges and a123 :)
