Double Capacity MintyBoost with 4-AA Battery Holder Modification

Step 11 Add some Insulation

Since the sides of the battery holder with the exposed metal connections will be very close to the sides of the Altoids tin add some electrical tape to both sides for insulation purposes as shown in the first image. You can also add some tape to the bottom of the holder to help keep the wires in place as shown in the second image.

This completes the battery holder modification. Now we are ready to connect the battery holder to the MintyBoost, prepare the Altoids tin and do the final assembly.

You could have just used a pair of 2 cell holders and wired the leads in paralell to the circuit board

I tried 2 dual cell holders at first. But I liked the fit of the quad cell holder better. Whatever your preference, when connecting banks of batteries in parallel I would recommend that you use diodes to isolate them before making the connection to your device.
