thx guys, always appreciate the help

Could use some additional help… I used these settings when I initially set up my ubox. I’m wondering if there are any changes that I can make to squeeze a bit more speed and/or range out of the motors/battery. (without damaging anything)

Setup: 12s4p p42a, BN 6384 170kv, ubox v1

Any advice is appreciated



Bump your motor amps to 90 per side and set your battery to 50 per side. Should bump up low end toque

As you have it rn, having higher battery amps than motor amps does nothing.

Those motors can also take 100 motor amps, but I’m not sure how much I trust a ubox with that.

I’ve got my Ubox V2 75V delivering 105 motor amps per side without a problem so far :crossed_fingers: And yes I’m hitting those figures!! Set to 75 battery amps per side too

I would change your settings to

40 battery amps per Side

And if you are running any sort of 6374 or larger motor try 90 and even 100 motor amps per side.

There is no reason to have higher battery than motor amps

what do you mean when you say per side? sorry dad I’m new to this

Do you see where it says

Direct active and 15

This means you are currently connected to one side of the vesc and your can ID 15 is the other side.

You can switch between there by clicking the 15.

So set those values to both CAN IDs

When you change the values on each side, before you move to the next side you have to scroll all the way down and hit “save to esc” then you have to do the save to the other CAN ID

ok, I did this to each side and saved both. am I correct?

what should my regen settings be? :thinking:

You regen looks fine, you are going to have really strong breaking at speed, so if you feel they are too strong, adjust it down to like -25 or -20 and see how that feels. Keep In mind if you are using the freesk8 tool you have to always charge the setting to both CAN IDs and save to both. Try out your new settings and let us know how the board feels, it should feel more gutsy at low speeds and still have really good all around performance.

Also with any setting changes always take it very easy your first couple rides and get used to the feel of your board

Feels great. Brakes at -40 aren’t quite punchy enough for me. Going to try 45-50. The torque difference is massive… makes my Low mode a lot more viable on hills, and High is going to probably destroy most production boards around. Surprised I rode this board with such strange settings for so long… Thanks again for all the help, really appreciate it.
