Dissimilar batterys ?
Connecting two batterys together ? The only factor that makes this a bad idea - is when the batterys are of different voltage range. As long as the 'chemistry' of the batterys are same - you can in fact connect a small capacity with a large capacity ... try to have them at similar charge levels and of similar amp capability .....
If this was not true - then someone explain why many boats go around with dissimilar capacity batterys that can be combined whether VSR system or the old 1-B-2-Off switch.
You can of course combine different 'chemistrys' but then BMS and other factors come into play. The main factor is that full charge voltage level is similar ...
