The problem is you don't have to get to 100% to have issues. Very few companies give you complete access to min/max voltage of the cells or a true 0-100%. It would be helpful to know more about the pack. If 13.6 nominal vs 15.5 still puts it about 88%. An interesting read is the Do's and Don'ts from Battery U. Last column is the lithium ion cells.
BU meta description needed...
I've been searching for info on the RESS in more detail without much look. It is really important to know this info if you want to manage the pack correctly. I was talking with a member of another forum who only supercharges (L3) his Tesla Model 3 as he lives in an apartment and already had 6% pack degradation in the first 6 months of ownership and less than 6k miles.
It isn't like the LW (or most any electric motorcycle) has range to spare. Even thinking about 19% degradation over 5 years as being acceptable to HD and that would really throw a spanner into the works for my current usage. That would still be within warranty specs. Knock almost 20% off the range and you basically have a fast Sondors Metacycle.
What I haven't seen anywhere is how much, if any, the performance degrades based on SoC. I've extensive testing on my Tesla to get an idea of the performance at lower SoC. On my Model S, even at 30% SoC, I've only lost about 0.1 seconds for the 0-60 time. My quarter mile has only fallen about .2 seconds. I don't really see any real fall off of acceleration until I am below 20%.
Even with at 30% charge I can still make an easy 100 miles on the highway at 75-80 mph and running the AC. So its is pretty easy to keep it at a low SoC to minimize degradation, still have good performance and decent range. With my fast L2 charging at home I can easily add about 30 miles of range per hour given the way I drive it.
That is why I am really sad that pretty much nobody but Zero offers decent L2 charging. The Zeros I test rode just died when their charge level was low. I've heard the LW stays pretty strong but never seen it actually quantified at different charge levels.
