2 ... 7s linked Mixed p 92 and 74 lithium DIY battery Build

[Anthony N]

My question i want to connect in series a 7s 92p 18650 diy battery to a
7s 74p 18650 battery in series to make a single 14s 48 volt battery is this workable ???
Or will the smaller 74p be over charged /discharged in use and charging they are all same age batteries tesla cell

ok the rest of the story i have added one 74p to a tesla cell to bring up the voltage from 25.2 to 29.4
and i have built a 92p 7 s 29.4 volt im hoping to connect in series it will be charged by a Growatt 6000 wt with charge controller to 57 volts
or i can split it into 2 7s with 2 smaller units with 2 charge controllers Thanks for the helppppppp...!!!

I'm terrified for you just by the asking.

Did you fuse each individual cell or use the fused nickel plate?

Did you capacity test all 644 cells?

BMS on both?

If any of the above "no" = shitshow.
