The game changer, of course, is the Li ion technology since if was so easy
for uninformed users to kill off their lead acid battery pack.

Li-Ion also has its issues. For example, even top brand manufacturers do
not seem to understand that it is not a good idea to top off a Li-Ion
battery at close to 100% charge and then leave the bike in the garage
that way. This results in premature aging and loss of capacity. The
smarter way is to offer 80% or so which is plenty for a short ride into
town. Then let users top it off in the morning when they expect to go on
a very long ride. In the same way, don't ride it all the way down to
where the low-batt cutoff turns it off, at least not often.
NiMH would be more robust, but that chemistry never seemed to catch on
before Lithium came on the scene.

Actually, L-ion doesn't like 100% charge under any circumstances.


It's ok if you use it right away. There is always a toll to be paid but
then it's small. Thing is, most people do not know. Sadly, many
engineers don't seem to know either and then they design stuff that
ruins batteries over time by charging them 100% every single time, and
people buy it.


New batteries are on the way. I'm wondering if they will be able to make
super-capacitors work. I read a short paragraph by a man who was a
graphene expert who seemed to think that super capacitors were already
on the horizon.


They say that for a couple of decades now :-)
