The packs you are using are 4x1.2V=4.8V. That's not enough for the HB to
operate on. You need to connect the two packs in series and then to the HB.
The red of one pack goes to the black of the other. The remaining two
wires, red and black, one from each pack then go to the coresponding
terminals on the HB. That way you have a 9.6V pack and the regulator has
enough room above 5V to operate.

| I am trying to connect the batteries to the HB but after hours of charging the screen doesn't turn ON. The batteries are two packs of 4 and I connect the two reds with +ve and the two blacks with -ve Is there any case that I connect the wires (...)
