Range Extender can be turned off / disabled via menu setting screen

[Stumpy]

A few here have speculated that the range extender can be disabled. We've got visual proof now that range extender can be turned off easily in the Scout's "Status" screen with the "Range Extender On/Off" toggle menu setting.

From -- 1st look at Infotainment Software UI -- Modes (Pet Mode, Camp Mode, Night Mode), Rear View Camera, 360 Degree Cameras, Range Extender On/Off

I was hoping for this. Allows me to have two trucks. Best of both worlds.

I must be misunderstanding the purpose of this. Why would you want to disable your range extender?

does the range extender use the 150 miles of gas before it switches all to battery mode? I guess I assumed it would be the opposite. You would use all the battery and then when needed the extender mode would pop on to give you an extra 150 miles to make it to a recharging spot

I was actually wondering if it could do that. Say you’re crossing a fairly deep river. You don’t have a snorkel to protect the generator. You switch the generator off, cross through the river in full electric mode, and no water goes into the intake.

It's tough to say without understanding the implementation of the range extender. It's always good to have the option, the example MrOzman mentioned could happen. Having some experience with Rivian I'm less concerned about having a software option at launch than I am understanding the specs and compromises.

I’m guessing this generator is probably 5-7kW charge rate. Maybe less. Its only purpose is to charge the main battery, not drive the vehicle. So you have to factor in how long it takes to charge the battery, while you’re driving and using the battery. This is probably why it needs to kick on as early as 150mi of driving. Then as you continue to drive there’s enough fuel to keep the generator going and charging the EV battery for the equivalent of another 350 miles (150+350).
