I have a brand new V5 kit that after charging the battery won’t power the brain. Other batteries power the brain - and I tried the failure battery on several brains.
The status lights are all fine and seem to act like a working battery.
When I try to power the brain, the status lights tun on like normal, so it receives the signal but a brain won’t actually power up.

Did you verify that the charger that charges the battery is plugged into an outlet? As in when you plug in the battery to a charger it blinks.
Update: I plugged back into the cahrger and after a while it went to a slow flashing red LED occurs once per second. I unplugged it and the error seems to clear. Pressing the button has it display 4 green lights.
