We have been building the 4WD Freenove car with a Raspberry Pi 4. We purchased two Samsung 18650 batteries.
When we try boot up from battery power the red LED turns on the Pi. However the green ACT LED doesn’t or barely lights up and we get no action!
If we plug the Pi in (while mounted and connected to the Freenove car) it boots up no problem.
What could cause this? The SD card works (evidenced by booting when plugged in), and we have red LED power light when powered via battery but it won’t boot!
Thoughts? Are my batteries dead? They are brand new!!
