100V to 18V Brushless Planer Conversion | Electric Makita 1900B

I used to rewind an electric planer from 100v to 18v one time already. You can see it    • 100V Electric Planer to 18V Battery C...  
This time I try to make it better than before, including lifetime, power and designing. The brushless motor system needs space for controller circuit, I put it in the battery adapter. The circular saw, angle grinder and chainsaw brushless motor controller will be better than this one (it is used with a drill), because it doesn't need a trigger switch. However, I can still use it with the planer. As a result, I can use this planer with 18V battery very well.
