60AH battery packs from Spirit Energy?

[Sgt Raven]

I found these on Amazon and then looked at them at their web site.
Was thinking about changing the configuration to 2P4S, for a 120AH battery.
I have to add my own BMS to them and will need extra bus bars.
Has anyone dealt with Spirit Energy?
Can anyone identify these cells?
Is there a reason my idea is bad?
Anything I'm missing with this?

OK, I have some more information. I can't put them together in a 2P4S battery due to their design.
I can do 4S2P but each will need it's own BMS.
The packs are made and assembled by Zhejiang GBS Energy Co.
