Translating step 7

Step 7
Use the battery tabs to solder the two batteries together. The tolerances around the battery pack are tight, so keep the overlaps and solder to a minimum. Solder the voltage regulator board between the batteries. Be careful not to heat the batteries too much. I used tape on the two ends of the batteries, but a heat shrink tube would work better.
