hey thanks. Well if the protek are crappy cells the I will probably go with something else. I still don't think it will draw a lot, but still a lot more than stock. My wheely king has a 13 inch wheel base and use clod size rims and tires. Gearing is low at 15/96 I believe. Now weight shouldn't be much different than stock other than the 1:8 lexan body and tires (which a lot more than stock derrer) I wish I had a scale and a motor tester. Do they even work on brushless like the one from muchmore. The thread was mainly to find out what cells these packs use but as u see I ramble on and wander alot. You answered my question perfectly except the tantric packs.
