Now apply the soldering material to both the wires and sealed material on the part of the wax. After that, put the soldering material on the plus and minus points of the battery as well as you have it. Now this parallel cable with wire wires. I.e. pair one wire battery plus and the second wire mains point.
Now pinch this battery with the glue on its own, but one support is available between each battery. There is no heat from one battery to another. Use cardboard for this support.
