Control of secondary battery system

Post by sandrobilbeisi » Fri Mar 09, 2018 6:43 pm

Hello folks

I have successfully achieved relay control of a secondary battery pack to drive a touchscreen
now I'm getting more ambitious ..

I have a little project that requires powering stepper motors via a HAT/Shield such as :
"Adafruit DC & Stepper Motor HAT for Raspberry Pi - Mini Kit"
the HAT provides power to the motors from a separate power supply between 5V-12V
the specs on the HAT are 1.2 A per motor, with 3A peak current

now I want to control a secondary on/off and battery charging circuit to drive the entire motor section
has anybody tried something like this ?
