Your future. At my age 25MPH can be hazardous. I’m firmly in the pike path crowd with zero interest in anything more than a 36V 20A sweet spot for my riding. 3 new 36V tracking with UPS. I bought a second after 5 years of consistent service from day one. The batteries I managed properly with my first satiator are still decent performers in warm weather and at 15A max. both from EM3ev in 2014.
The newer format will be bike mounted. The old shop setup.I have Grin controllers as well as infineon 12fet that are, as you know have programable voltages. My 48V and 52V packs have aged out. Low miles but incredibly saggy running 1000W, and speed is just not what I need or want. 20AH 36V 35E cells are super packs for me.
I’m not criticising 72V, I’d still be driving aircooled Bugs if I could.
Cheap 72V packs scare me... exactly as played out on a ludicrous BBSHD and 72V China special on a NY stoop.
