Dialing back a Convoy GT FC40 Driver

Here’s the tutorial itself:

What did you mod today?

I tinkered a bit with Convoy’s 12V 2,5A GT-FC40 driver. I changed it to 6V output and adjusted boost converters input limit to higher value. It was limited to 10A, but MP3431 boost converter should handle higher. I also changed bigger 1R5 valued inductor to it from broken Convoy driver. With 6,7 mOhm current sense resistor mine gives an output of 6,2A and draws 12A from battery. This with battery voltage of 4,1. [image] [image]
