Hi there!
I’m building a Raspberry Pi / Navio2 / Ardupilot solar-powered boat based on Flytec and would appreciate advice on power system design. So I have:
- brushed motors with unknown specs, originally powered with 7.4V - so this is my input voltage and I use these drivers
- 7.2V NiMH AA battery pack (1.2V x 6)
- power module to route the original 7.2V to motors and regulated 5V to Navio2
- 14.5V / 1.3A solar panel
So the question is how to design the power system so that the boat uses the battery pack (and charges it) and solar panel simultaneously? I’m fairly unexperienced with electronics - is there an off-the-shelf power controller with such functionality?
Or maybe a good online tutorial on it?
Sincerely
Max
