I've been busy lately, but I'll try to answer some questions.
How much was the extra hub and why did you need a hub--doesn't E+ offer a 'B' pack that is not in a hub??!!?
I got all the parts to assemble a wheel with the battery hub and a wire harness to give me some room to work with for about $700 or so.
E+ hasn't had the Lipo battery since I got the bike in November. This way was the next best thing available.
since you have 2 hub batteries now your usage is split and you can expect double life , double millage on both batteries.
Your original hub battery is used much less now and it should last twice as long.
This would be true if I was running the same speed and rationing the batteries. As I posted earlier my shortest trips are 13 miles. One battery can do good with that at a decent speed. I usually try to get my average speed as close to 20MPH as I can. So if I do a typical 28 mile run I'm using both batteries with some to spare.
Metal Man, have you had any problems with your spokes?
Yes I did, this was after my solid tire experiment. I totally blame the tires for my spoke trouble.
