It's a little sad that we need to actually say this, but:
Don't be an asshole or you will be permanently banned.
Respectful debate is totally OK, criticizing a product is fine, but being verbally abusive will not be tolerated.
Focus on discussing the idea, not attacking the person.

i love the idea, but everything i know tells me that replacing one cell in a series parallel array with a fresh one is a bad idea.
over it's life, a battery's capacity and internal resistance change, so it's not only important to match batteries in a pack by exact type, but also condition. otherwise, the cells won't charge / discharge evenly, leading to overdischarge / overcharge, or, if managed by the bms, drastically reduced performance (basically all cells are limited to the worst one's performance).
still, the concept is fantastic, so i hope they found a way to work around this issue!
