Mot Upgrade for '16 CC Precedent (JE prefix)

[GCoA]

Alright...So I've searched the forums but seem to have only dug myself deeper into confusion. Looking for a torque upgrade to get up hills with 4 passengers (rear passengers are just children). Would an upgrade consisting of an Admiral Motor MOT-A4 with a XCT500IQ Alltrax controller and 400 AMP Solenoid be compatible with a 2016 Club Car Precedent with the serial prefix (JE)? I've seen that this is an I2 HF CHG, which would make it an Excel system with no OBC...basically a fleet cart, but that this upgrade is for the IQ system specifically. If installing a new motor and controller does it really even matter at this point? Also wondering if this upgrade would effect the use of the E.R.I.C charger for some reason. Thanks everyone!
