4s 8000 lipo what brand?

[superek4]

I m not sure how but I was told 6s 5000 won't run longer than 4s 8000 becoz of the amount of Mah, per cell does not increase run time but speed coz more cells. Correct me if I m wrong.

I can only take up to 750g which is one sided. 6s 6000 is 900g way too heavy. I can't parallel coz my setup is 1 sided batt n they are 150mm long.

I m racing against nitro already no pit stop is a advantage, but with a batt swap abt 40sec I lose 1 lap already.

I will post my setup pics later now using my crappy iPhone. I m chosing between truerc 4s 8000 n maxamps 4s 8000( but wallet empty)

If there's any other batt abt truerc price or abit more I dun mind thx guys
