Hi, recently I started thinking about building mid-driven motorcycle and I am trying to find out if there is any possible way of extracting proper values from the manufacturer performance chart to use Grins motor simulator tool. I see there is no direct way, but maybe with some try and error...

I bought it from Nexun.pl and they keep telling me that the programming works but I have tried 6 computers with 3 operating systems and none of it worked. I came to conclusion that there is problem in the controller or the programming software. Everything seems fine until I try to read the...

Hi, where do I get technical support for ML7260 controllers?

Here are photos of it, it is definitely beyond cheap chinese controllers and I really like how it is designed... And it was rather cheap too (90€). It is rated for 20s and 60A battery / 170A phase max. I am not sure if it is FOC, it seems more like sine to me.

I am sorry to inform You that You got it totally wrong. Please read some battery life related threads to get the basics right first.

Wh is calculated Ah x Voltage. Real life Ah would be little lower value, let us say 3,3Ah. 3,3x13=42,9Ah x 25,2V = 1081Wh. How much current does it consume during dive or what is the wattage of the motor? This is important before making cell choice.
