Genset while underway

[Hydro]

We do not have an inverter only a battery charger that typically cycles on & off. We have ran the generator & battery charger underway for up to 14 hour cruise (2 engines). We have owned this boat for almost 2 years. So far no issues. Are we damaging the batteries? I had not really thought about it until reading this thread.

Thank you all for the answers.

We do have an inverter but it is not wired for the stove/oven. The other reason for asking about running underway was as a back up should an alternator fail we would have a back up way to charge batteries while heading to a port.

Guess i will give it a try and hope that the shutdown devices work as advertised.
