Did you document the build? I, and I'm sure others, would be interested in the parts list and build details.

Thanks for sharing

Thanks Not sure on the max current because the voltmeters were just old ebay purchases that I had lying around, I wouldn't push them past 5A without knowing what they are capable of. The 12v side of things is bottle necked by whatever voltmeter you use, which can easily be pushed higher by getting a higher capacity meter. The variable side however is limited to 1.5A output by the DC/DC converter (AA0236 from jaycar).

As far as parts lists everything can be interchanged with any old switches and plugs you have lying around, except for the AA0236 (6-28V DC/3-15V DC converter). The whole build revolved around a voltmeter for input - power out/power to the DC converter - and a voltmeter after DC conversion.

I cannot see how you connect to your battery so here is how I do mine.
My batteries are multitasking between astro and camping and also taken to Girl Guide jamborees so they need to be bullet proof and simple to connect.
So I chose to make up short Anderson fused connecting tails that are glued to the top of the batteries as per pics.
This means when I am not around, things such as chargers, loads and solar panels can be connected without getting the polarity wrong, even in the dark.

Thanks I've just got alligator clips for now. I'm using car batteries at the moment, I'll save making up a battery box for when I get a nice deep cycle battery. Yours look good.

Tim.
