Yes, that’s likely true. But the user has to balance that with safety, and decide how much risk they’re willing to take. There’s always a risk with lithium-ion, even when used “normally”. It’s very small, but that risk does go up when operated outside the recommended specs.

These cells aren’t even supposed to be used for flashlights. Large currents, anode and cathode right next to each other on one end of the tube, with just a small plastic or cardboard separator, and a really thin plastic wrap, to stop an easy short. I can hear government bureaucrats wringing their hands…
