Hi folks:
So I currently have a 24 volt set up using eight 304 AH Eve cells. I'm using an 8S current connect BMS. I had some problems initially with my vendor from China, and long story short, I ended up with an extra four batteries, so I now have 12. I don't want to get into replacing the BMS, and would end up with an oddball voltage (36V) if I did anything in series. i.e. 2 groups of six batteries. So I'm thinking if I combined banks of two cells in parallel, and then combined those 4 mini banks of parallel into series with the other 4 batteries combined in series that would still give me two 12 volt banks I could combine to make 24. One bank would just have greater amp hour capacity. And because I'm combining two cells in parallel, I'm assuming the BMS is only going to monitor both two cells banks as one and not the individual cells. I don't think there's any way to monitor all 12 cells individually?
I could use some help with the wiring. I'm going to sketch something up here of what I think it should look like, but please correct me before I do something wrong if it looks funky. I've never done anything like this before, so thanks in advance.
