Surron controller upgrade

[Wattster]

Most of the controllers available for the Surron are overpriced for what you get. I stared doing some looking and came a crossed the Votol Controllers. The EMRON kit from Electro and Co uses the em150/2 controller and is a decent price for what you get. I chose the em150 as it seems to be more reliable to connect with. You can order the em150 non CAN bus and program cable from QS motor and with the DKD display for less then $300 shipped to the USA. Goal of this thread is to get all the docs, diagrams and videos in one place. If you would like to follow along and do the same please do!

This content, files and documents are meant to be used for the DIY builder not someone to copy and build a kit to sell to others. Electro and Co already does a nice kit if you want to buy one.

A look inside of the em150,

Great thread.
Good luck getting this to work and I look forward to the results.

Brackets showed up, it's going to be a late night

All the hardware mounts up, now for the fun part.

So after cutting all the cloth tape off I got excited and cut everything that had to do with the stock controller. It thins down nice.
There is a red with white coming off the battery that goes to a fuse then the key then it turns to red with black and will be used to power the display and boot the controller via the ING wire. There is a green wire off the batt that goes to the common ground.
Horn and wires powering the horn button and sport/Eco switch can be left alone. You just need the white with green to hook up to the sport wire on the controller.
DC/DC can be left alone if you don't cut any of it's 4 wires and will power the black wires with 12v. One quick look at the wire size will tell you it's only going to take low amp draw.

Ich habe Surron-Stecker zum Votol gemacht. Den Surron-Kabelbaum in Ruhe gelassen. Der Surron Controller ist so, zurück in 10 min.

All buttoned up and the motor even spins when I hit the throttle!

 

[Wattster]

With a bypassed battery this thing boggies!

 

[SlowCo]

What are the numbers now? Phase and battery amps? Any performance data yet? Acceleration time?

 

[Quinc]

Sub'd! great details!

Have the amps capped at 90. Didn't take any data from before the change but there is a big difference in the seat of the pants dyno. Very happy with the controller and glad to have a speedo on the bike too.
