Maximum 4S size lipo in a TBS disco?

[sopher]

I saw in a post the since the higher Mah rating and bigger size does not equal ore flight time.

AND I see the maximum height is 42mm from the red posts (tubes) on the TBS.

What is the maximum size battery that can give the most fligth time in a TBS?

Maximum weight i read should be no more than 400g for the battery.

i get my best flight times under the biggest load on sky lipo 4000mah 40c 4s... I also have 3300 40c turnigy and 3000 40c that flies in it. That's with 1000kv motors on 8" props
