I maidened my UL-1 this past weekend with stock everything using True RC 4000mAh rated at 15C or 60 amps. What a great ride. 
This machine is great. The batteries puffed however and temps were 150-160F. Motor and esc at around 100-110F. I did run until stutter bump and True RC said they were run too long. He suggested I get more amp hour (capacity) or parallel a third pack.
I have read where some have paralleled 3ea identical 4s pack to get increased capacity, but can I parallel a third 2S pack and then connect them in series and get 4S1.5P? I still get 4S voltage but also increased capacity. Also, do I need to parallel a third pack with the exact same capacity or can it be different capacity such as paralleling one 2S 4000mAh and one 2sa at 3600mAh and with different C ratings?
Tks in advance,
Ed
