Gen.2 Price of HYBRID batterie$ are thru the roof=What are the future options?

What does the video you just linked have anything to do with what we are talking about? It doesn't matter if the battery won't blow up like a lithium ion battery...............the BMS/battery packs for the v2 and 2.5s are badly designed and the fact that the only argument against them being defective is "well they won't explode" is just insanely silly.

The fact is Nexpower sold dangerous batteries, then immediately did a "very soft" recall on a very dangerous issue speaks a ton on possible future experiences, even if they change the BMS or battery chemistry.

Again, this is why in some countries you need an engineering degree/license to do the stuff Jack is doing (because it IS dangerous/hazardous, including to potential consumers). You can't just go "my bad, buy my new battery and try again".
