Balancing will be a nightmare I guess, or just dont do it. Nice idea for the advanced user but I would not let my parents fiddle around with lose 18650 cells for the sake of their house burning down.
I see a niche application but personally hope they get it to market and make it compatible with Shimano. My double sized battery is a frankenbattery: pcb from original with custom printed case fitting onto the original attachment device using the batteries from two original batteries. Measured and balanced of course. Safety is "meh" I guess because DIY. I'd like to replace it with something more properly designed.
I did my masters thesis on how to balance batteries with very little information on each individual battery a-priori! Unfortunately I didn’t get to do experimental stuff because it was the middle of Covid, I only had simulation data. You can do some interesting things, though I wonder how many issues we missed/avoided by working only in simulation.
Edit: here’s the publication if you’re curious: https://www.sciencedirect.com/science/article/pii/S240589632...
Edit-edit: wow I got two citations!!! Never thought anyone would read my paper, that’s amazing.
