Hello pedelecers.
i know there is loads of threads titled controller mod on this and other forums. But I can't find anywhere that explains this problem in a way I can apply it to my setup.
I've been charging my battery pack up to under 63v since adding a rear hub motor to my mid drive project. The controller caps were only rated to 63v
Yesterday I finally open the controller and upgraded the caps. It looks to me and google as my mosfets are fine to run at 67.2 (max) volts. But I was wondering about the voltage regulator (lm317t) because I was working fine at 63v and nothing blow; do I need to change anything?
Can I assume adding 4.2 volts will be fine too. Or should I adjust resisters?
I hope these images are clear enough that you can help me. As you can see the controller is a generic Chinese controller made by szktdz.com.
I don't mind that the lvc is is going to be 40 odd volts. It's the same on my other controlller so I monitor battery voltage while riding.
Is there anything else I need to check or change before fully charing my battery pack?
While I had the controllers off yesterday I took the oppitunity to add a little solder the the shunt on my mid drives controller upping it to about 35a max. It a GNG stock controller; what do you reckon the max I can up this to? I didn't think to check the mosfets when I had it open so can't google them. But I did add some solder to the pdb tracks.
Can't wait to test this setup at 67.2v. At below 60v I was able to hit just over 40mph on a relitively flat track. By my calculations I should have over 6000w of power when fully charged.
As always thanks for reading
