The only batteries I'm concerned with regarding any rides actually will never stop me from taking said ride. First is my cell phone which since I first began utilizing them in the mid-90's I have instinctively left it charging when I was situated anyplace so I generally good there. Second and newest are my wireless earbuds (EarFun Free, which BTW are waterproof, inexpensive, low profile and auto-default from stereo to mono if you only use one as I do) which again when I'm not using them are in their charger cradle and with a supposed 9+ hr battery life I never get close to burning up. Lastly, are my bar/helmet lights. My use of these is limited to maybe once a week or so on sub 2 hr rides and only if I can't scoot out work earlier enough to avoid the daylight savings darkness. That's really it and if all of those crapped out, I could still pedal around without issue. I'd miss hearing hardcore like [Slant](https://slant.bandcamp.com/album/1) in my earhole, but whatever.
On a related note, one of the big ups for Speshy's latest electro wonder bikes is a very involved TCU that possesses a full color touch screen with a zillion options. On the contrary, the alloy versions of the Levo don't come with it instead using their older simple yet effective bar system and button control, but without any performance detriment. As I have zero desire to have basically an iPhone attached to my bars (with some of the bike computer offerings) I see no point to spending more for said TCU that I would likely leave on stealth mode.
