    MidNite CC citing Battery Over Voltage

    As for the alerts when PV isn't inputting, the Midnite monitors voltage at all times regardless of charge sources and will alert when it sees voltage above the "max volts" setting in the "Advanced" config menu. Also your generator charge source may be sensing a slightly lower voltage than the...

    I'm glad to see that someone has experienced in real world usage what my experiments found to be true.

    "more work ages the cell" so according to you (and what I've been saying) less work ages the cell less. So how is it worse to have two cells doing less work than having one cell doing all the work? "We also run into problems in the charge side...." This is the fundamental misunderstanding. One...

    I’m going to do a set of engineering drawings and submit it to Rolls/Dekka/several manufacturers and ask if they see a problem and would warranty their cells in that configuration. Hopefully I will get a clear “no way” or “we see no problem” and “yes, we would warranty the cells”.

    My position is that it is very possible. But obviously others are disagreeing with me. My findings are that two (or more) paralleled cells will function as a single cell. If there is a “weaker” cell in that parallel “block”, then the “stronger” cell will simply “do more of the work”, but less...

    I did discuss the topic presented. Just because you disagree doesn’t make me “not discussing the topic”. People are also conflating the issue of “parallel STRINGS” and “parallel CELLS” in a single string. My argument is about parallel cells in a single string. But people keep arguing about...

    My name isn’t Mark. I already terminated my discussion with you earlier and the fact that you can’t even respect someone enough to get their name right shows that I was right to terminate. As I said earlier, I gain no benefit from changing your mind. I don’t make any money from it, I’m not...

    There never was any "phallus" waving. People are also confusing parallel strings with parallel cells. But I'm done arguing. It isn't worth it.

    Extending a part worn battery bank

    The thing is that the question of "Which degree do you have so we can determine what your expertise is" wasn't asked. What was said and implied was "hey, your school doesn't even offer the program that you supposedly earned a degree in", which if true would be a "gotcha" moment that I wasn't...

    Mine is small. But I'm happy with it.

    Why? You're already questioning it's existence to the point where you tried to insinuate that the school doesn't even have a science program. I tune people like that out. If you disagree with my findings about the batteries, that's fine. But don't attack my education.

    Extending a part worn battery bank

    How do I draw the opposite conclusions to that of the author? It says in green "This is possible and won’t cause any major issues". The part in red is the "cover my ass" statement that "if you don't know what you're doing, it could be a problem. But knowing what you're doing shouldn't be a...

    noob top balancing - over charged my cells to 4.2v

    I bought my first cells from Jack Rickard. RIP Jack. (The grey cells in the picture are the cells I bought from him 6 years ago. I've abused these cells and they are still going strong!)

    If you believe that the parallel causes the issue, then you're free to continue believing that. I get no benefit by changing your mind. I don't sell battery systems or do install services or anything like that. So I will leave it at that.

    " In general when one 6V battery goes bad the other in series will quickly follow." I would agree. That happens because the cells were all operated under the same conditions for exactly the same length of time. They all got old together. I fly airplanes and the same thing happens to the light...
