How to make one big battery out of several batteries (car/motorcyle/deep cycle), for a sound system

Hey everybody,

I need your help on building a single battery out of several smaller batteries for a sound system in a particular environment that forbids the use of a fuel-powered generator and where electrical networks to plug into are absent. For now I'm just researching various portable batteries and think deep cycle ones are probably most adapted to the needs of a sound system running for 8-12 hours, but the only working example I've heard of so far is made up of several motorcycle batteries.

I'm really starting from scratch and reviewing all my old electronics classes which I've never so far had to put into use, so bear with me :) I'm really keen on learning.

As an indication, the sound system will be small with two high/mid built-in amplifier speakers and a woofer. Probably will need to run a few lights/lasers, that sort of thing as well, but that'll be a bonus.

Thanks in advance

I'm trying to build an ebike. so there's this guy from youtube who has his own channel. main thing what he promotes is building diy batteries. I guess he has some "how to-s" on his website as well. hope this helps
