TomEV, what you say all makes sense. Do you think two controllers like I diagrammed above (post #19) would work? I just need to know whether the field windings have the same resistance as the armature windings. I need a current EVer to do the simple voltmeter test I mentioned in that post. If I choose to go with commercial controllers, it would save a pile of money. Two used Alltrax 48V 500A controllers for a total of $500 vs one Curtis higher voltage controller for $800 or more. These are just numbers....I really have no idea.
Anybody want to donate a controller? HA!
How about a picture of my current battery stash....
