What size of diode do I need to connect my solar panels up to two sealed 12V batteries connected in series? Answered

I'm not worried about over charge for they will have constant drain on them.

I'm not being dumb, honest, but I don't see your connections there making sense ! Please post what you have - any idea of the open circuit volts of one cell ? I'm worried you'll get circulating currents in your panels which are A Bad Thing.

I'm guessing sense I'm using 28 .5V at something like 3.5A each connected in a series of six with 4 of them set up as 5 Parallel and 2 set up as 3 Parallel and please correct me if I'm wrong and I'm not sure if I can even do this but. 3V 70A?

I'm sorry I'm new at this but the cells say 3.6 a's so I think the highest would be would be 18 a's right? I totally did that last one wrong with adding across the series
