Yah I use T Power too. Theyre awesome batteries. Only problem is that they arent the cheapest batteries out there. I think Electrifly makes cheaper lipos and they must be pretty good quality cuz the rest of their products are nice.
Another good battery is made by Dualsky. The name on it is Power. Very nice battery and theyre cheaper too. I only paid 60 bucks for a 1700 MAH for 1 of my planes.
