What can I use to power the charger and charge my batteries when I am at the track or somewhere that there isn't an AC wall power outlet to connect to (if the automotive battery is not recommended)?
You "can" use a standard Lead-acid(automotive) battery if needed but we do not recoomend it because of the tendency to false peak and give "Input voltage" warnings. Most people simply use the battery that is in their car which most of the time is not fully charged and do not provide the needed voltage.
During the writing of the instruciton manual for our Flight Charger we had a big spike in customers calling claiming their charger would not work because they were getting "Input voltage" warnings. 100% of these customers did not realize that there source battery was not fully charged and upon recharging it they solved there own problem. This is why we put the message that we did not recommend using said battery as a power supply.
