I need a battery that can take a charge of 250-300 amps anyone know of one?
no such thing, batteries are rated in volts+amp-hours… so many volts at amps for so many hours
then theres the deep cycle vs. short cycle… an RV battery which is used for a long period between charges is a deep cycle, it releases less current for longer, a quick discharging battery will give you more amps but will run out of juice more quickly
