two metal contacts were salvaged from a existing (generic) 18650 battery pack that was too large to be placed within the unit.

a small hole was made in the cavity for the battery pack for wires to be run through to the internal contacts and then soldered into place. the unit is then able to charge and discharge the batteries. Some small modification was necessary to the internal cavity to fit the pack.

Ensure both batteries are equally charged/discharged!
