i really do not care for 9 volt batteries and we have so many things that already run off of aa's . i was hoping to be able to run this unit off of a larger 12 volt sla cell i have here ? is that ok ?
how about a car battery or a deep cell , i have a few of those and we take those to the woods sometimes and have little jam sessions .its nice because i can recharge these and i don't have to worry about them running out all the time .
