Getting some new power for my Revo, need to decide between the two. The Hyperions are 6500mAh and TP's are 5000's. C rating 35C/65C(G3) and 45C/90C(TP).
Price is the same, TP's have a bit lower internal resistance, I guess this is good when braking?

Looking at the graphs, TP's should last more cycles? I will try to follow the 80% discharge "rule" and won't always charge at 20A.
