Connecting different Ah lead acid batteries in series
No, do not connect different capacity batteries in series, because after the lowest A-h capacity battery is discharged, it will be charged in reverse by the other batteries, quickly destroying that, and possibly outgassing dangerous hydrogen. You would also need to charge batteries individually, or the smaller batteries would be overcharged, again, releasing H2.
