Trustfire batteries are known to generally be cheap crap batteries. Best to stay away from them and pretty much any of the battery brands that end in fire

For the price, OK for me, there was a bad lot a while back but they do need frequent re-charging

FWIW: In general, Big Blue sells great light. But Big blue batteries, from what little I have seen (and what was advertised across various sites) generally have custom protection circuits built into the battery package. After testing and tearing one (and only one) apart. I suspect is has to do with in-rush or surge current and constant current stability. It's unique and it does limit usage of other more effective and efficient Li-ion batteries. This is akin to a car dealer tying your hands and say you have to use their band of OEM tires forever!! I only suppose BB does this for owner and warranty protection issues. That's seems fine; they are a great business and they make wonderful products, imho.
The general observation w/r/t Trustfire batteries (or any other battery) is unfounded, imho. If you drain or over-draw from any, repeat any, unprotected Li-ion (or variants of Li-ion batteries cobalt, manganese) you might / probably get the same results--especially if there is no effective light power management / protection circuit in your light. But protected Trustfire protected batteries are fine. Some have carefully wired / removed protection circuits at times to overcome the problem of battery incompatibility across various lights. But lights have a unique situation as compared to a RC airplane power needs (for example). In general, I usually don't care about light warranties since most products simply drop in new parts which I have done as well. Some folks are very finicky about warranties. For me anyway, sort of my light, my money I'll do what I want approach.
I've upgraded many old light aluminum housings with new electronics and LED combinations. For example, I build a bright UW Fluo light with components into an old, but extremely rugged Diver Rite backup light housings. Works great. Price..about $20. btw, those small Dive Rite lights lasted me 5 years and hundreds of UW hours. I don't know who in DR designed the inside of these lights, but they did a great job in viewing how the items were assembled, again, imho.
I've re-purposed some old housings into 1K lumen, 2 hour backups strobe light for about $14. Great guide light when your in echelon dive formation. My latest (when I have time project) is re-purposing an old, barbo-light housing into a 3K lumen, 110-degree video light at 2.5 hours for under $30.
The internal LED drivers (not the LED arrays) from what I have seen and reverse engineered are the note that unique. Anyway I hope the helps. My observations are derived from what was in front so I a careful not to speculate rover generalize. Most of this work occurred a long time ago so please take this with a grain of salt. Anyway, this is just one view from the bleachers. Cheerio.
