Multiple Batteries in Parallel
I have several regular 12v batteries that are different sizes. Can I safely hook them up in parallel without damaging any of them?

I think if you parallel a 100 ah and a 200 ah battery together. The 100 ah battery will be fully charged before the 200 ah battery is fully charged.
The same would happen when discharging. The 100 ah will discharge fully before the 200 ah battery will.
Not so. If they are properly balanced for load and charging, they "equalize" with each other and maintain the same SOC throughout, at the same voltages. BTDT. They get down to 50% together at the same time and recharge together to full at the same time.
