I keep all my boards at 100% charge.
I use my boards about ten times a day. Any time I go to any place, I’m on a board. That includes work, grocery shopping, going to get dinner, going out to a bar on Friday night, taking the dog out for potty, or just riding around because I want to.
If the battery can’t be held at 100% charge, then it’s defective in my opinion. I can’t wait 2 hours after I decide I need to go somewhere while my ride charges. With all due respect, fuck that.
