Help in Series Different Brand of Batteries with the same CAPACITY

[emcharles]

Hello guys,
Please i need help.
I previously got 2pcs REPT 230ah from Xuba months ago (not used, not charged, not touched even now)
Recently, i needed to make a project and require 12v battery and i thought of buying another 2pcs 230ah REPT (i understand they wont be the same batch but thats manageable for the use)

After payment, seller told me that REPT 230ah doesnt come with QRCODE anylonger (which i had to search other sellers and get same claim) referring it to Grade B cells.

He was offering to send me 2pcs 230ah EVE instead.
I don't know if i should accept, not sure if it will be logical to use it with 2pcs 230ah REPT i already have in series, to make a 12v battery.

Worried about the cycle, resistance and unequal charging even though there would be a passive balancer from my bms.

otherwise i'd just pay for another EXTRA 2pcs 230ah EVE and just build it (while forgetting the first months ago 230ah REPT, since i can't get it again) but this option will cost me more and can only choose it if there is NO OTHER OPTION as it ain't in my budget for now.

Please help me if connecting in Series of 2pcs 230ah EVE + 2pcs 230ah REPT to make 12v battery (4s1p) is deal.

otherwise i will have no other choice than to get total 4pcs 230ah EVE and ditch my current 2pcs 230ah REPT

Thanks guys

Mixing REPT 280Ah and EVE 280Ah? Is this safe?

I have a current assortment of 12 cells. I'm considering making a 24V battery bank of two batteries; 1p8s each. This is instead of my current plan for 3 12V batteries (2x Lishen 272, 1x EVE 280). In this 24V setup, one battery will be all Lishen 272 matched and balanced. The other battery will...

the left-over two pcs will come in handy for other application(s)
