max wattage on 300amp alt + batteries

[lextruck]

Im wondering how many batteries a 300 amp alt can keep charged in a daily driver and how many watts I can run off them. Either XS power or Batcap batteries not sure yet.

[HunterJohnson]

couldnt it charge as many as you have? Like 10 group 3100 batteries?

[HunterJohnson]

You would be running off mostly battery power if you had 15000 watts, but then when you stop playing your system your alt will charge the batteries back up?

Just guessing

The amperage draw is more what you need to know to have that question answered, not wattage. Amperage needs come from what wattage your amps are needing at a particular efficiency, at a particular voltage. So you need to know what kind of pull the amps are gonna want before you can figure out which amps to get. A battery bank and HO can only replenish what is being demanded.

essentially as many as you want, but what your amplifiers amp draw will be a determining factor on the decision of what to do with an electrical system.

I want to run 2 rf 2500.1s and a 4 channel. Just don't wanna give up my AC for a second alt if possible. So was checking possibilities of one alt and several batteries instead.
