My generator could run double level 2 charges but won't fit in the trunk.
Why do you want a battery trailer?
You do know that every day you don't use it the battery trailer the battery it's life is still withering away?
The best industrial lead acid stand by batteries kept at a steady 70°F and rarely used still get replaced about every 5 or 6 years.
Rarely used stand by generators can last 30 or 40 years and all they need changed is the oil, fuel and battery if it has one.
