So the solar charger at just over 2A would take 13 hours for ea of my SLA cells *3 = 39 hours of sunlight. It would take 10h to charge each of the LiFePO batteries (20Ah*3 batteries [4 cell LiFePO units]) = 30 hours of sunlight at the end of my ride. I need to rethink the SLA charging for sure at 2A... I wasn't going to do my "trip" until I had the LiFePO's.

I have two routes - north with a serviced campground (sounds good right now at 50KM/30mi) and south (about 65KM/41mi, a parking lot) - where I'll get with only sunlight to recharge with and only one day to camp. Solar charging is most definitely out....

The upside of the south route is that I only have to ride through 2 creek valleys in beautiful subalpine terrain (11 KM) to hit a long downhill (16KM) - after that downhill is a campground with service, and then it's a flat ride (50KM/30mi) home. I'd include maps, terrain models and such for this trip but...

My one constraint was that I have to do it in a weekend, with hopefully some time for prime flyfishing for brook, cutthroat, rainbow and bull trout, all very world class. I'd leave Friday nite and be back hopefully Sunday dinner with time to clean up before work. This means I have to shave lbs off my camping and fishing gear because easily 1/2 the weight in the trailer will be batteries.

I had already decided on the 6A charger for the LiFePO4 (3.3h recharge time)...

One thing you probably have never considered about owning a car and having a driver's license is that you are tracked in every police database by your driver's license number. As a culture-jammer, I have no reason to be so tracked. As a tree-hugger, I can't justify burning a tank of gas to get to where I can launch a bike. I need to get there, and I want to relax and have a good time, and this eBike may just help me go be happy for a while. Endorphins are good, adrenalin is awesome, but why overtax the glands?
