I might have to go back to battery school, but I thought li-po was just li-on chemistry in a plastic bag (as opposed to a steel can) and that plastic bag is called the pouch. Which would imply that the Diamond is both a li-on and a li-po.
I’m no battery expert so if I got that wrong, point me in the right direction and I’ll educate myself.
I think we’ll have to disagree to agree here.
We’re on the same page that BMS have (likely) prevented orders of magnitude more damage than they have caused. My point is that they still can cause damage-- faulty solder connections, faulty components, abrupt shut-off of current at high power causing an ESC explosion, etc…-- and so they are a risk factor. If we had as-of-yet-imaginary batteries which did not need a BMS to stay safe from fire, then the BMS adds fire risk.
Personally, I see BMSes as one of the biggest risks in the powerchain. There is no clear consensus on whether you need one, and even if you agree you need one there are a myriad of application toplogies. And even if you agree on the topology, there are sound arguments that balancing should happen on the discharged side or on the charged side.
The end result is that we’re splicing in high-energy components without really understanding what problems we’re solving. The solution is to throw tons of money at the BMS so that it has extremely high reliability and never, ever, ever incorrectly shuts down while we’re on takeoff. But no one wants to spend $1k on a BMS which has unclear value, so there’s a ton of crap on the market and the only way to disambiguate is word of mouth.
