UPDATE: TL;DR - as discussed below, storing li-ion batteries in lasers is widely agreed to be safe and carry minimal if any risk of fire, battery damage, or idle battery drain compared to other storage methods.

(Note that I am specifically asking about lasers that use rechargeable li-ion batteries - not primary lithium batteries or other battery types)
Disregarding accidental laser exposure concerns for now, can we finally store our li-ion batteries in our lasers for convenience sake? These same batteries stay in smartphones 24/7 365 days a year for years and they virtually never have problems aside from reaching their 300-500 charge/discharge cycle limit. Is there something special in smartphone and other electronics' circuitry that allows them to have permanently fixed and safe batteries, or can we finally start storing our li-ion batteries in our lasers?
I tried looking for threads of the same nature, but they are over a decade old or close to it, so I'd like to raise the question once again now that li-ion batteries themselves and our knowledge of them has has matured significantly.
For a little context, I recently bought a Sanwu Pocket Series 492nm 100mw as a "daily carry" laser with the intention of using it every now and then for demonstration. The question popped into my head though... should I carry the 10440 battery outside of the laser? Given how li-ion batteries are permanently fixed in and sparingly used in things like portable speakers, I don't see any reason why I can't safely keep my 10440 battery inside my laser all the time.
