Thinking of running a leisure battery of a Digital relay , then using the 2nd battery to power all my additional stuff .
Thinking I could run my main stereo off it , and inverter , also a load of usb powered hubs running to the dash somewhere to power various things.
I could also use the inverter to power a small charger to top up main battery if needed.
Idea behind it all is that I can never run my main battery down with anything, also I can easily top up leisure battery by removal and charging in the house.
Does anyone think this is a good idea ?
