Everything stated by SMC is 100% legit, please re-read the article I linked, they know what they are talking about.
I will never run separate packs in series ever again

smc web site is a prime example of someone paraphrasing someone else's research not understanding it and then posting it on their own. That is the biggest load of hogwash and bull I've ever read. The person doesn't understand current flow resistance or voltage. You see the same current through a Series Battery both A and B. A resistance is the same for the most part whether it's a single pack 6s or two 3s packs wired together in series. im not going thro that this and picking it apart. but understand its full of lies and miss information and a general lack of understanding one the writers part mainly to sell batteries.
as a side note
there miss information will not stop me from buying there batteries as there cheap. and good quality batteries.
and there reaility in there is only a few factories that actually make batteries. i for get something like 3-5 factory smc is just like all those other batteries seller buying from them branding and selling.
Edit: I just readed finded reading smc article for my amusingment. I think the person that wrote the article English is a second... No third language. My punctuation and grammar is bad but there's is on another level.
