vts1029: Thanks for the info. Why a bus bar rather than cables connecting +/+ and -/- for 2 batteries connected in parallel? Does this have to do with balancing input and output to batteries? If so, I think I can accommodate that by connecting to + on one battery and - on the other.
I think I probably need to do some more research regarding cabling for BMS equipped batteries. I thought I could connect 2 same manufacturer and size batteries together pretty much like I would 2 lead acid or AGM 12v batteries of same manufacturer and size. Apparently, I'm missing something regarding these 2 12v LiFePo4 BMS equipped batteries? So, the Battery Management System (BMS) for an individual battery may have a conflict when 2 of the same batteries are connected together in series? Is there anything on the spec sheet that would tell me about this and if so what? I don't feel like I should have to contact a manufacturer every time I want to connect 2 identical 12v batteries together in series, but if so, it is another reason to use a 12v system versus a 24v system. Thanks again. Please advise.
The spade terminals are small on these batteries. a buss bar just makes it easier to connect together. In the end it really doesn't matter how you physically wire them provided they are sized correctly for the loads applied.
I do not know when it comes to the BMS. I have seen some sellers say that this battery can or can not be connected in series. An AGM battery is vastly different than one of these Lithium. If you really want a 24v system I would purchase individual cells and get an 8s BMS. Or just connect them and see if they let out the smoke.
