What are you planning to run them in? with what motor esc setup?

I have been running the TrueRC 8000mah 5s setup in a revo and savage for along time with no issues at all. They are a great setup. My opinion is as long as the lipos are capable of 80A continuous in a MT they should be fine. I would not run the smaller 5000mah packs in this setup though they are only good for 50A cont.

What vehicle/motor/esc and what pack size are you considering.

Generally, you will just need to run a higher capacity pack to get the amp output up high enough. For Example: If a 4000mah 20C pack is good enough for your application then a 8000mah 10C pack is good enough as well. You just need to make sure you can fit it.
