I used the 2s1p 5000mah in my big Flashlight and I could see in the dark. Was pretty cool for 20 minutes, when I figured that I still had my dark sunglasses on.
I tested the 2 packs in series in my Rustler. Gearing was set at 58/25 with a Tekno Neu 1400kv 1512 motor. I need swap the motor out or increase my gearing to bring the load out. I peaked at 80Amps which is quite embarrassing for me. I mean I'm used to 180+ amps with my A123's. But that is due to me swapping out the heavy beadlocks for those lightweight Jaco's.
At 80.14A, voltage was at 14.9! Peak watts was at 1214W. Not too shabby, but I want to see something higher than that. More will follow.
