What converter is in my trailer? 2017 Heartland

[Grit_dog]

I believe it’s located behind the breaker/fuse panel and accessible by removing the bottom drawer next to it. However the release for the drawer slide is messed up and I don’t need another project right now. Lol
Just put 2 new batteries in it and would feel better knowing if it’s a smart charger type.
Rig is a 2017 Heartland torque T29.
I suspect it is, as the prev owner said he’s left it plugged in a lot and the original batteries weren’t totally fried.
Anyone with a similar vintage Heartland trailer?
Thanks.

If you don't like your converter, consider upgrading to an inverter/charger and disabling the stock converter.

Never mind. Didn’t know they now have combo fuse panels/converters.
It’s a 55A WFCO. Sposedly a smart charger too so that’s cool.
