Re: [RE-wrenches] Five L16s in a 24V string?

Jerry, The five batteries aren't in series. I thought I made that clear, but maybe not. Two are in parallel at 6V at the positive end, and then that pair are in series with the remaining three. Allan

Since multiple batteries failed ("the one that always fails"), did he buy one new battery each time and tie it to the old failing one? Or, did he start with a new bank and create the parallel at that time? Since he’s an “old timer” he may be mixing different age batteries in the bank. I see

I would think that doing this would be asking for un-balanced batteries in the string (un-equal battery voltage) But I guess I can't argue with success ? Put the positive battery in the middle then so it won't be on the end ? :) :-) boB On 10/1/2015 2:07 PM, Starlight Solar Power

I think I would go with Lithium technology for a bi-polar battery or installer disorder, ask your doctor or psychiatric health provider ;-) I am chalking this up to old-time off-grid lore I've never heard of before. and I'm an old-timer at off-grid too. The way to protect those string end

But boB… Wouldn’t you end up with a bi-polar battery bank? Or just a bi-polar installer? Seriously though, I have never seen such a thing either in my 30+ years of working with battery systems. It’s kind of like using an L16 as the last battery on a string of golf-cart batteries. Yes, it

I have18 on a 48 volt outback system just set the CC and chargrr up a little. My concern about 5 on a 24 volt is how deep the batteries really get charged, 7.5 v a battery is 37.5 and thats above the inverter operating range same issue with nickle iron. There may not be good spec gravity for long
