Need some lipo size help here

Those look good, but a bit to wide, im really looking for a short narrow pack, I dont mind buying 2 of those hyperion packs and wiring them in 2P.. But a good choice for sure!

When I race, it will be with 6 cells and a stock 18R motor, this is to have some cheap fun with while my TC is charging. I race 10.5 or MOD sedan, so no on the racing 18R with them lol

I love the range of KV, My back straight is 164 ft!!!! Y E A H ! NEED motor lol my track is darn big, and theres a perfect sweeper at the end of the straight, so motor is def needed, and with the mongoose being a 380 can, it should be a torquey motor, So im hoping I can gear it pretty high, in case I need more speed
