ultra bee 80v batteries

I'm running a sumo build, and originally was going to bypass the battery and do a tc1000. But I realized bypass is the stupidest thing you could do, this was like last year, and stuck with tc1000, stock battery, stock motor. And then the chain drive conversion sprocket got fucked up and when I tried to take it off it wouldn't budge even with every tool on the planet. I ended up getting a tm50pro. So now it's only right to get a 80v battery. so here we are.

So I know the chi is always good but the other option was ewatt because the stingyroger guy was using it. But extra 1k and worse performance? Chi is a strong contender but any other brands to look at?
