I would buy a dedicated battery for that.

If you have a harbor freight near you. They sell a small generator that is like $90. Works great just to charge a few packs on race day. It will run Charger,fan and a light that I know of.

Don’t go too small, it depends on how fast you are charging, especially the 4S. Lead acids can deliver a lot of current, but the voltage drops significantly under even moderate loads. Can easily drop below the minimum needed for a typical RC charger. Here is a recent similar thread for reference:

If you stick with your car battery, start it frequently, expect shorter life depending on how often. Did it for years, definitely makes a difference. If you can spring for it a generator is great to have.
