You really shouldnt run simliar batteries that have a different discharge rate. The weakness is the pack with the lowest C rating. Its going to be the one that can be damaged. Now if all your doing is proving a setup change or hardware mod then as long as its not for more then a few seconds its probably ok. But this is where tolerance for rule bending comes about and it can lead to catastrophe if you make such things a habit. Its better to use binding rules and not push things.

John's comments are not wrong but its worth covering again what the C rating really means. The 35C label means Hyperion claim it is safe to pull up to 35 x 5 (ie 175) Amps out of their pack. Turnigy believe it is safe to pull up to 25 x 5 Amps out of their pack. You can easily pull 200C Amps or more out of either pack. All you have to do is short them out.
So, if you wire in series your set is safe to 25 C (125 Amps) and if you wire them in parallel your set is safe to 50 C (250 Amps). If you pull more amps you will damage the small pack - but then you could consider it as the "fuse"Comment
