Can Batteries with multiple AH can be connected eachother Serial/Parallel?
The batteries can be connected in parallel, but you have to use diode isolation. Otherwise, the stronger battery will charge the weaker battery when they are in parallel and not under load. This needs to be done even when the batteries are identical to each other. The diodes need to be large enough to handle the continuous and peak current to the inverter. This means the diodes themselves are going to be huge because they will need to carry a few hundred amperes! In space satellite power systems, redundant battery strings are connected to a main bus through diodes, so this method works. Recharging the batteries becomes a pain because you have to charge them separately. The diodes only allow current out of the batteries, not in.
