Dual battery setup?

[RichardT]

If you want to get a little fancy you can do what I do, which is run a second battery about 100-120amp/hr which is isolated by a redarc 1220 controller which also doubles as a dc/dc charger allowing for maximum charging of the second battery.

once the voltage drops below 12.7v i tihnk, will have to check, the controller stops charging the second battery and isolates the starter battery so you can always start in the morning.

Another step up is the 1240 controller that has solar input if you want to get fancy.

Thanks, I'll look in to those

I made a battery box with a separator and use a goal zero panel to keep it up. the video is easier than typing it all out.

Wow, that's so cool and well thought out, it's almost scary, though a little complicated for me I think (especially because I won't have any need to switch it between vehicles). Still you had some good explanations in your vid that will be helpful I think, thank you for sharing

Just curious, what did a setup like that run? And, did you find that box made already? Or did you make that custom?

I made it. So the cost wasn't that bad, but I will say there is some time in it.

As for making it portable, at one time didn't think I needed either. But now its the only way i would have it. in VA this week there have been a lot of people with out power for 7 days or more (it wasn't that long for us) i brought this in uses it for day's to run all kinds of stuff.
