Battery under load
I've been looking for an answer to a specific question, on past discussions on other forums and I also have an open topic on another forum but it always gets into the weeds of what batteries and what ...

What about forgetting my batteries and getting back to my original question. When a battery is under a load, the voltage you would read drops, correct? So assuming someone doesn't have $200 worth of dignostic equipment, but only a way to check voltage, if the reading drops to say 11.8v but rebounds above 12 when the load is removed, is any damage being done to the battery at that low voltage with the load applied?
No damage. EG, an inverter will alarm at 11v and quit at 10.5v under load. Running a microwave on inverter on four batts at 60% SOC, you could see 11.3v, no problem, and when the microwave finishes, voltage should go back to 12.2/12.3
There is still something not right, but not clear what. Can you "get away with it" as is? No idea.
