The above lengths consider the resistance of the battery and cables only and do not take into
account any additional interconnects. The above lengths factor in a maximum voltage drop of 2% of
the nominal voltage. The above lengths are for operation at 25°C/77°F. For high temperature
installations (50°C/122°F) increase wire gauge by 20%.
