Yesterday i was looking for a solution to charge some LiPo High Voltage 4.35v 1S-6S Packs for my quad-copter.
So i stumbled upon one of your older youtube video's.
Watched a lot of them :)

I'm very surprised and still very exited.
The code looks understandable for a non coder like me.

If it is not already possible, and if it does not take a complete rewrite of the exiting code.
I would like to give it a try to implement the following functions:

  • Modular Balance Charger for,
  • Lipo / LiPo HV 4.35v Packs.
  • Ranging from 1S to 12S.
    • The Modules can be mixed and matched to get the desired balance leads.
      This way with 12 modules you can charge:
      • 1x 6S + 2x 2S + 2x 1S
      • 2x 4S + 1x 2S + 2x 1S
      • you get the point.
  • 100mAh - 5000mAh
  • Settings Charge / Discharge / Storage / Fast Charge

Worst case i have to make a custom module to make it work.
I think the easiest solution would be, to combine 6 Module v4.50 onto one board. To be able to charge 6S batteries.

another option:
I have a lot of Logic-Level MOSFET's (5Amp or 10Amp).
Is it possible to use 6 of them to balance charge a LiPo Pack and cut when full?

Using the Analog Inputs for Sensing and the PWM for Charging?

Or just keep it stupid simpel:
What about these kind of ic's i see it comes with usb.
Unfortunately this model only 500mAh charging.

What do you think, is it doable?
Please point me the best direction to start digging in the code.
I just saw i one of your videos you can add a Victron Cerbo.

You said you are looking for beta testers:
