many batterys

alright i have my 250amp alt on its way. i have a walmart shitty staring battery and a data safe 120ah battery in back.

i was wondering if i could run a diffrent battery with the data safe one. if i were to keep them AGM batterys would i be good? or do i even need another battery,

i do have it set up where i cant run my radio when the car is off bc it'll drain the back battery before the front, if that even matters (i heard it hurts the alt)

im running a 3000.1 AP at peak watts there fused with a 250amp

The more AGM batts you have, the better. AS LONG AS, you have enough alternator to charge them. I think you'd be safe with another battery in the back if you wanted.
