Hello fellow DIYers. Just joined the forum so yes, I have a problem. I did a search first but didn't find what I'm looking for. My problem? I have a 24v system and off grid for 15+ years. I'm using (8@6v) L16 US batteries for the first time. They are in series and then paralleled for the 24v. 1/2 the system is boiling. The other half is not. The batteries are 5-7 yrs old. With a battery hydrometer the cells in the boiling batteries are reading from high fair to good. The other bank is reading good on all cells. What am I missing? I have never run into this problem before. We are only able to make it thru 1 night of power and hope that the sun is shining the next day to keep us going before firing up the generator. We have 1440 watts of solar which used to keep us going. Now it's a struggle. Any help would be appreciated.
