Battery power is GO
The boombox (aka "LL Cooler J") is now fully capable of running from a 12-volt battery. I got a 55Ah Werker AGM Deep Cycle battery. It powered the music at mid-party volume levels for five hours and judging from the battery voltage at the end of the run, I suspect it could run at those volume levels for 12+ hours.
Note the 2 Farad power cap; I have no concrete data here, but I believe this significantly helps with battery life by smoothing out the power drawn from the battery from instant to instant.
Although there is a plug going into the A/C outlet inside the cooler [ :D ], there's nothing hooked up to it at the moment.
