Yup, 7s seems to be the limit for el cheapo controllers. I'm treating these batteries as an experiment. They should give a better performance than the hyperion I was using previously purely on the greater voltage but i'll need to see how they handle the power demands. I'm not overly sure on the figures they quote for discharge but time will tell.

Gonna bring both along to the champs so I can run in a few combinations should it be required.
