How do I know the Rshunt value of my controller? And how do I change that?
The RShunt value is usually on a printed sticker on the back of the controller. If it's not there, ask the guy who sold it to you. You DON'T change the controller's RShunt value, you change the value in your CA to match.cwah said:How do I know the Rshunt value of my controller? And how do I change that?

dogman said:True about the connectors, but if they were where all the watts were going, you'd see the melted ones.

Definitely a worthy cause for performance reason especially for wires that carry high current. Minimizing the voltage drop can never be a bad thing.NeilP said:..., maybe I have been worrying too much about short thick cables and few bigger connectors on my bike.
You won't. What ever you saw before will be cut in half now. That's a lot closer to reality but still too high. At WORST it should take no more than 150W for you to cruise at 12mph on flat terrain. So you may have to determine the actual controller RShunt value using the reference method mentioned by Jeremy earlier in this thread.cwah said:Guys, Lyen told me to that the controller has 2 mOhm value. So I'm going to change the one from the CA and see if I still have high value.
NeilP said:i tried riding at 12mph today, and ended up with a constant reading of about 120W on my bike, and that is with 26 inch wheels at about 35psi, smooth road tyres
Surprised, surprised!Jeremy Harris said:Nice to know that theory can match reality now and again.....
