Long story short... The will probably wrap up this build thread for the most part. The battery module works like a champ, as you'll see, and I wanted to include one shot here because it harkens back to my original carbon-fiber battery tray where the expansion chambers used to be.
So, I heard about an Alternative Energy Day at Mount Washington. Steeper than Pikes Peak, same vertical climb, and with a longer history of auto racing. It still has an unpaved section too. Except it was about a month away, and I didn't have a big lipo pack yet. I casted about to a few friends, but couldn't get a pack together in time. I was ready to give up and shoot for next year, then I did some Math
If I pulled every moderately healthy battery I had together and somehow got it on the bike, I had the 2-2.5kwh that I hoped would get me up the mountain.
Here's what that looked like:
That's my SLA 20ah pack in the belly, and my lipo in the module. I had this in my backpack:
I stole that from my son's electric moped. What can I say, he's off to college, I get what's left behind, right?
After waiting out the winds and temps on the summit, I made the bid once they opened the mountain. At about 1.5mi I swapped the connectors off the lead and onto the lipo, which pulled me up to the 6 mile mark (the road is about 8mi to the summit). At that stop I pulled out the lipo pack and slapped in the Headways, which pulled all the way to about 10' short of the parking lot... but close enough to claim I made it!
Here's the final approach, shot by the guy running the event:
Here's the shot on the summit:
...for which I earned this coveted bit of bling:
The temps on the summit were around 26ºF with a wind of around 50mph. Needless to say, I really didn't linger much...
Here's the video of the ride:

if you're interested...
The bike worked incredibly well, and the whole swappable battery pack worked better than I could have hoped. To top it off, I got a report that a "production electric bike" had made the attempt this summer (I don't know which brand) and had to turn back at the Halfway House site, with spent batteries. On the ride down he smoked his brakes, too. I'm happy to say my 1971 drum brakes performed flawlessly!
Oh, not for nuthin'? I'm the third electric motorcycle in history to make the peak!
