Hi,
I'm making a electric surfboard.
I already have:
the problems:
A video of the test of the drive system:

The esc is out of sync on low speeds. But i still need to configure the esc to a 4 pole motor.
We did the test with 2 start-booster for a truck, a 12v and 24V booster. I wired them in serie so i became 36V.
I'm making a electric surfboard.
I already have:
Jet,motor,surfboard

- I also made a mount for the jet and the motor:

- The aquastar 200A ESC

- The motor
http://www.skyrc.com/index.php?route=product/product&path=39_82&product_id=139
It is the :SK-400008-01 wired in star. and deliver 6.3KW.
So i need a battery pack of 50 v for getting the maximum power and a rpm of 30.000.
- I also make the electronics with an arduino. It measure the cell voltage and current.
Also it measure the temperature of the motor, esc, battery pack
the problems:
- A waterproof thumb throttle.
I looked a long time for this. Do you know where i can get it somewhere?
Or have a better idea?
- Something important:
The battery pack. I'm considering to make a battery pack out of the A123 amp20 cells in config 14p1s:

- A good bms for the battery pack.
I'm also stuck at this. I don't find one that is capable of the current that i draw. Around 150A
