FSIP Controller Model Numbers

FSIP list two D2 controller models. Does anyone know the difference. They are 7R504D2 and 7R354D2. The price difference is $150. I cannot read mine as its still installed in the car.

No OU812R2D2’s left?

I believe the 7R504D2 may be a 500 amp vs the 7R354D2 at 350.

Best to call them to verify, if it is max amp capacity, you can always get the larger one.

They are both rated for 500A. Used with the 6 HP motor.

Yeah, best to call FSIP then, the T2s were 350 and they upgrade them to 500 (per Rodney). Could be the 350D2 is already upgraded.
