Worked with the ElectroBrapp guys yesterday and got the controller settings dialed in. 6500 rpms, instant power, (in the video it had soft start) and will hit the motors full power of 33ft\lbs of torque. If the motor can reach 6500rpms the impeller will be spinning around 9100rpms. First video I had...

*Also note I am using a 30ft USB extension cord and it works fine.

Are you on windows? If you search the thread there are different tips and solutions to get past that message. Yes I'm using Windows 10. I've searched through this entire thread and so far none of the info has helped me solve the problem. It seems that the USB/Serial side of the USB to CAN adapter i...

Get a Sur-ron. Have you not seen one before? They're for dwarves and children. I have one with every mod on it. It does awesome with me 6' 240lbs. You be you. gvDSEysVFqM LOL I was just riding my kids KDX 50. (smallest kid mx bike you can get.) And now I know what I must look like. :lol:

My neighbor is 6'5 260 rides a stock one and jumps the piss out of his. My only complaint is the short wheelbase m...

Get a Sur-ron.

Ive made this mistake, its only fixed by making both sides sprockets larger in diameter is the way to make your chain more quiet. The link below shows the effect of tooth count vs chain vibration. It looks like you have room to package 2x the number of teeth at least, doing that will knock out most...

Motor sprocket 14T Driveshaft sprocket 10T (Did this so I could adjust rpm/torque with sprockets) Even drive / Even driven.... sprockets... requires a chain with an ODD number of links or.... else your wear will be 2x faster, or even more. Just like if you have an even number of links, a even drivi...

Going to get some graphite into the rollers on the chain. Hopefully reduce the heat and noise some. Also working on figuring out the best way to attatch a coupler to the motor splines.

Video of the motor out of the water. This is just over half throttle:

Interesting project! Yes, I would second the post above - minimal gains in power or 'per charge' battery life from the 4.2V charge, and will most likely shorten the overall life of the battery by some amount. If you absolutely want to try it, there are likely some trim pots in your charger to contr...

.My Ant bms/battery only charges to 4.158 per cell. Any tips on getting it to charge up to the full 4.20v per cell? 20s2p SPIM08HP battery..... Seriously ?..why ? There will be no noticeable change in performance from that 0.8 volt increase of pack voltage,..but you will likely seriously reduce the...

Built this over the winter with my 8 year old. He took every nut and bolt off the ski and did the fiberglass! So please give him a like and sub on youtube. :) Couple things I could use some help with. My Ant bms/battery only charges to 4.158 per cell. Any tips on getting it to charge up to the full ...

Also this shrink wrap fits perfect over these batteries. And will cover all your wires. Comes with enough to do a few of them too.

Has anyone ever found documentation or had success coding their own interface to a votol controller? I’d like to get readings from my EM-150’s on something smaller than a laptop. I’m able to with the Daly BMS and want to build some safety features and logging in to my build. I don’t care if it’s ar...

Try changing from com1 to com2 com3 com4 etc until it connects.



Has anyone hooked up a wireless remote kill switch to one of these? Thinking something for when the kiddos ride.

There is a guy on facebook sur-ron group that makes them.

Looks great! For the wires I tucked them all down one side on mine using each wires to hold down the wire behind it. . Also wait until you try and play with the votol software configuration. It's a pain in the arse. but you can adjust the throttle input voltages. https://www.endless-sphere.com/forum...

Figured out the cause of my motor wanting to jump off the bench.. Checking the HDC box. I have tried setting it from 4000-7000 and everything in between but still wants to jump off the bench. Keeping the box unchecked the motor spins up smooth but goes to 7k+ rpms. video is with HDC checked: pMViWH0...

Where is the best place to source these from? Been a while since I was in the market, and the shipping is just insane. Is there any US domestic stock of them?

Only place stateside I know of. https://www.electroandcompany.com/motors-kit

This thing is sweet!

Loaded that .ini file and wow! Motor has some power now! Are you having any issues running it at 6k+ rpms? any tips on lowering the rpms to 4k?

Chico area got hammered today. Tons of rain and hail.
