    cell arrangement dangerous?

    Hello! I'm putting together 2 8s 24V batteries in parallel. I was thinking with this arrangement below I could keep my cables shorter. Does the fact that the main +/- terminals are so close together make you cringe? My intuition makes me think the the outer cells might heat up more than the...

    combining 12V and 24v panels?

    Awesome, thanks. Could you please double check my math for 3 X 200W 24V panels? 25°C + (150V - 112.8V)/112.8V/-.004/°C 25°C + (37.2V/112.8V)/-.004/°C 25°C + (0.329787234042553)/-.004/°C 25°C + -82.4°C = -57.4°C

    combining 12V and 24v panels?

    Ok! Thanks, y'all. This really helpful. Re: cold temps. I hadn't considered the efficiency boost as potential problem - is there a standard curve for figuring out what voltage a panel might output at a given temp? Or would the manufacturer provide this? I am full time, and -8C ain't s$!7...

    combining 12V and 24v panels?

    Dang it, sorry I put the wrong info for the 200W panels - they are 24V and I acutally have 4 of them on hand. Everything I wrote I believe is accurate though. I'll reattach the correct info-graphics for both panels. The 100W 12v Slim is just one I was considering - to use the smaller...

    combining 12V and 24v panels?

    Hey @sunshine_eggo, thanks for taking the time. Unfortunately, I am confused by your message. I like the first of your proposed scenarios the most. But doesn't this statement contradict the diagram? I don't know a lot obviously or I wouldn't be here, but brother, this diagram is showing...

    combining 12V and 24v panels?

    Hi folks! Thanks Will and company for making such an awesome community! I wanted to give my questions some context and talk about my project in general. I'm self-building a Ford Transit high roof (non-extended) camper. I have 16 x 304Ah factory direct Eve cells which I intend to assemble into...
