Upsss... that's a shorter autonomy than I expected, with my life po I can reach 30 + plus hours non stop music and else. So the only thing I can do is try the 30 amp each, that will be a total o 60 amp per SSD, dangerous... there is no 60 amp switch in the business either, just bought an on - of military switch that is rated at 35 amp max.
Regarding Pauls clock SSD maybe he is talking 3 amp consumption for the start, like a pc when you start it draws a lot of amps then it drops a lot the power consumption.
Hard to say exactly how long discharging time will be. Depends on many factors, including how “nice” you want to be against your batteries. But with these 30Ah cells that I linked to earlier, shouldn't be a problem to achieve a day-long listening time. If you want to
What should you have a 60 or a 35A switch for? It's very important that the switch have good contact characteristics (very low contact resistance), but it’s both wrong and completely unnecessary to dimension it for the entire battery capacity.
Something important I don’t think I mentioned before: Batteries should always be disconnected from the device before charging. Switching off or disconnect plus is enough, minus or earth should always be grounded at one single point, ie, star grounding, in the computer chassis. Preferably all other minus should also be connected to this point.
