bike charge controller – Mexico version!

I met Gustavo at the HCF bike day last week. He wanted a similar system to the bike cinema I’m making for HCF.

I made a modified version of the charge controller in a tiny box. It took about 4 hours to build and test, and then another 4 hours to modify the software.

During stress testing I found that the mosfet I used for low voltage cutout was getting too hot. I had to remove that element of the design because of the short time available.

  • The box monitors voltage and current coming in and out of the battery,
  • Protects generator with a 60A diode,
  • Shows battery high/med/low status lights,
  • Shows power generation vs power consumption,
  • Broken – Low voltage cut out battery protection.
