Just picked up a Vant shorty, 7.4 5000mah 100c from dirtcheap for $49.99. I always have a lot of good luck with their batteries. They tend to be very powerful and are of good quality, highly recommend.

I love Vant batteries. I've never had an issue with them and have owned a dozen or more over the years.

That shorty has some real power.

Vant lipos are primo excellent. Power, longevity, no puff.

were do you get them?

Vant Battery ? Dirt Cheap RC

i think , could be wrong , that there are only a handfull of lipo makers and a ton of different brand stickers they paste on them. I know thats the same with 1to1 scale parts but if you like them use them.
