GEL versus AGM
I watched a video were it was suggested the max DOD of Gel Cell is 80 percent versus 50 percent of AGM and the charge time for both is around 2-3 hours. A max DOD of 80 percent would put the Gel Cell...

Pnichols, my ex650 bro. That's good to know that the 650 dc output is not too much! How many amps is it, do u know off the top?
Naio ... your little ultra-quiet EX650 should be able to dump, maximum, around 35-38 amps into a battery during charge.
Golly! And that's not too much for my 90aH gels? Just double checking, 'cause it seems like a lot.
Naio ... how many amps that your gel battery will draw from your EX650 depends upon not only on what the capacity of the EX650 generator is ... it also depends upon what DC voltage is winding up on the gel battery terminals while the generator is running.
You can adjust how much voltage winds up on the gel battery terminals if you use a proper gel battery charger (or a charger with a gel battery setting) that you then power from the EX650. In your particular situation, I would recommend against using the EX650's 12 volt direct battery charging output terminals because the voltage on these terminals may be too high for your gel battery such the battery would in turn accept too much current too fast from the EX650 .... thus the battery might run too hot when charging this way and hence could go into thermal runaway and destroy itself.
I recommend using a specific get battery charger (or a charger with a gel battery setting) on your gel battery. You then can power that charger from the EX650 or from shore power. :)
