Are you saying that @Chibatterysystems, after taking that first picture picture, took off all the tape, added fish-paper, and then put fiberglass tape back on?
I’m specifically talking about the lack of fishpaper in these places:
Should be fine but did you use ring insulators? I think more important as I had a battery that shorted not using one. But i used 21700 cells and they didn’t start a fire, just two cells died but my battery pack still had voltage. I think 21700 designed that way
The same reason we use ring insulators on the positive terminal.
Esk8s have a lot of vibrations and can degrade a battery in various ways.
Better safe than sorry.
We would not be having this discussion if we were talking about a static or low vibration application.
The groups are extremely well secured with other methods. If there was ever a reason to do it (even a single failure in the many years) I would implement that in my build method.
Failures due short circuit between p group have happened. Maybe not in one of your packs but they have.
As far as I am concerned it is a simple additional safety measure and I see no reason not to do it.
I see your point of view and it’s certainly good for extra safety. If there was ever even a sign of that problem in my batteries then I would have implemented that in my batteries.
Sorry op for the slight derail. But I just wanted to say that while I would personally use fishpaper between P groups and recommend everyone else to do so because it adds to reducing possible shorts with very little extra work (literally just cutting it to size), I can attest to @Chibatterysystems’s expertise. Out of the hundreds and possibly even thousands of packs he’s built, I don’t believe he’s had any error on his part. I’m not sure what percentage of the packs he’s built is for onewheels, but no one has had a failure in his onewheel battery mods and I can argue that most onewheels get a little more abused than an esk8.
Thank you for that. I’ve certainly made minor mistakes in the past and there is no dodging that but I strive for the highest quality and safest batteries. My build method is refined from years of building and customer feedback.
