What are the best 3s batteries I can buy for my Align Trex 450 Pro V2? I’ve got a 3700kv Turnigy motor, 35 amp Castle ESC, 325mm Align main blades, Microbeast FBL gyro, Spektrum satellite receiver, KST servos (cyclic & tail). Money is not an issue. I’d prefer to pay a lot if I can get 5 or 6 minutes of flight time out of them.
