PRIMEPACT 66G and 66LP Recreational Vehicle Generators

◆6.8.2 BATTERY CABLES

Using battery cables that are too long or too small in diameter may cause a drop in voltage, which causes starting problems. For the best cold weather starting, the voltage drop between battery terminals and the gen- erator connection point should not exceed 0.12 volts per 100 amperes of cranking current.

PRIMEPACT generators are rated at about 100 DC amperes of cranking current.

Select battery cables based on (a) cable length and (b) prevailing ambient temperatures. Generally, the longer the cable and the colder the weather, the larger the cable size must be, as shown in the chart.
