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

[baipin]

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 be 4 EVE 280Ah cells and 4 REPT 280Ah cells. Physical size is nearly the same; terminals are at slightly different height, within about 3mm of each other, so flexible bus bars will work. Electrically, they are close: The EVE cells have a IR of 0.16 whereas the REPT have an IR of 0.22. Is this close enough? For what it's worth, the Lishen cells in the other battery (a separate pack with its own BMS) have an IR of 0.12. Is it okay to mix these cells, especially the 4 EVE and 4 REPT cells wired in series to forma single 24V battery?

Shouldn't be a problem. The different height terminals is a challenge but it sounds like you have a plan.

I will also need to do this as one of my EVE cells has a problem and it seems REPT is the only available cell now.
