I have SOK batteries, and in my research I never saw that as an issue.
The rated specs for each battery is 100 amps discharge and 50 amps charging.
On the SOK forum the moderator who works for SOK says it can charge at 70 amps and discharge at 130 amps without issue., so with 2 in parallel you could discharge 270 amps continuous with a higher peak.
I have 4 of them, and no issues with starting the generator. I have not been to the page recently, but there were lots of folks with two 206 ah batteries, and none of them that I saw had issues with starting the generator.
Do you know how many amps it takes to start your generator? I would be very surprised if 2 SOK 206ah batteries had any issues starting it.
SOK support is by email and they usually get back to you in about a day, not sure what the SOK dealer was talking about.
If you are on Facebook you may want to join the SOK group and explain your issue, complete with your generator model and starter current requirements.
