jacob did a recent video introducing the new z series subwoofer. in the vid you can see a bank of batterys connected to a batt charger . ive used the same setup but with only one charger and 1 batt in my garage worked great for what i used it for . decent battery charger around 50 bucks
true whatever works best for the individual budget,accessibility etcMaybe someone else then. I don't like the battery/charger setup personally. I'd prefer a bank of power supplies that never decay, discharge, etc. Only downside is slightly lower voltage.
