Enduro Battery Heating

[R1Tom]

I think you are dead on here.

To get heat "out" from the core of a Bosch requires a lot more energy/heat in the center, because it has to travel all the way to the jacket to get picked up and used. In the Enduro motor, it is picked up where it is created (in the core), meaning the motor does not have to superheat to get similar benefit.

Another nice evolution, and another data point for anybody on the fence about which motor to buy.

You are making a pretty big assumption that somehow the heat in the quads is bad. If the components of the motor are designed to handle the temperatures experienced, then nothing to worry about. In addition similar thoughts could be made about the dual....like now that it is oil bath cooled, they might get gasket leaks and be a maintenance problem.

I am not saying that is case....but I am also not concluding the heat is somehow shortening the life of the quad motors.

Its one reason I went with the DM Enduro.

Then they shouldn't represent them in the red zone when they get that hot, if they have better tolerances.

Good thought. Are the oil leaks more likely than the glycol leaks? Not being snarky, genuinely interested since I own an oil-cooled one.

Glycol cleans off the concrete driveway easier, I can tell you that.

That is a separate issue and I agree. Unless it is a problem, in which all the quad motors will be dying way too early, which I doubt.

Who knows...just like who knows if the duals are going to last forever...because...oil cooling.

I didn't say anything about the heat being bad. Just that it has to produce a lot more heat to get a similar effect. More of a comment on efficiency.

Well, since you went there, better cooling is often closely associated with better performance and longer component life. All else being equal of course.

Ultimately the energy in equals energy out. So higher internal temps don't mean less efficient as long as it ultimately makes it to coolant and not atmosphere. But if it is making to atmosphere you are correct. The air cooled quad would be less efficient on that element.

The rub is in that all else being equal. It's a crap shoot till we all pile miles on them. I am hoping we all are winners and these things last mega long!

Further quad data point. No snowflake icon this time but nearly similar starting temps, same drive, same time of day

Also, @Riviot this one's for you buddy! Although admittedly I'm more of a Bing man myself?
