Hi, I''m planning to use an audio amp that accepts 5-12v DC and hook it up to a 12v sealed lead acid battery. Will the amp keep sucking power until it hits its drop out voltage (5v), which will then in theory ruin the sealed lead acid battery because it''s only supposed to be drained to (I believe) 11.5v? Amp Battery Thanks for the help!
