Guys the weighted packs are for racing... especially offroad. Everyone running lipo packs is adding lead to the car to make up for the weight that is lost by tossing the nickel packs. It's about setup and handling, and to some degree it's to meet min legal weight.

If you think it's stupid, you don't understand the application.

The reason it's good to have the pack pre-weighted is that you don't have to add anything, lead under or on top of the pack, etc.... like you do with any other lipo.

Seems quite a stretch to use their "leaded" option as another thing to bash them with. I think it's $10 for the lead??? At any rate, you don't pay for it unless you want it.
