Hi all,
I’m not too sure where to start. I’ve been reading a lot recently for my conversion project.
Even though I have broader decisions to make (still hesitating between eZee and MXUS kits from ebikes.ca), I also had specific technical questions.
So I’m pretty much set on going with a Grin kit. Let’s assume I am going with the MXUS rear kit. My initial thought was to go with the C7240-GR controller (36-72V 40A) even though I probably would not need such power demanding levels initially. Just to be futureproof. Upon further reading the Controller Selection section at http://www.ebikes.ca/product-info/grin-kits.html I gather that it may not be such a good idea. That if I select this controller, I better have a battery that can push out 40A or more (continuous, I assume). It wouldn’t be recommended to use a battery that’s only rated 30A continuous. I suppose it’s not recommended as in, it’s not good for the battery to draw current from it at its rated limit. Am I understanding this correctly? Should I aim for a controller that’s rated just a bit under the battery rating, i.e. get a 25A controller for a 30A battery?
