Corkscrew:
Don't forget a power supply. I got a order in on a couple 500Watt Meanwells. I'm using 2 tractor batteries now. Charging batteries to charge batteries is just too much trouble. I really like the PowerPoles for connectors.

The crimp tool is really nice. I'll also have 8 5000mAh 6s Turnigy's when the second set of 4 arrive.
