Powertools use the same batteries as flashlights. Candlepowerforums is the place to go if you want to see what comes from using cheap batteries, cheap chargers, and counterfeit batteries. There's that YouTube thing to...
The batteries can vent from overcharging, overdischarging, too rapid a discharge rate, and just spontaneously from being at a low charge state from sitting too long without a charge.
I'm not sure I'm getting you here? Are you saying there haven't been cars, Phones, Laptops, Vapes, various board toys, Airliners catching fire, etc, all "exploding" from venting? You can spend all night on Youtube watching this phenomenon if you're a flat earther type.
The only way to mitigate the risk is to use the safest battery chemistry, use a quality charger, and use quality cells, and use them respectfully. To do those things costs $$$. No way around that. Everything else is Roulette.
There is one other way, don't use Lithium...
But since Lithium is at least as addictive as Cocaine, Heroin, and now the ubiquitous various analogs of Fentanyl, I don't see getting off the Li bandwagon as being in my future. However, I try to maintain a healthy respect for the destructive potential in that little cell that more often than not is attached to my forehead.
I will acknowledge that more damage is done by AA and AAA Alkaline Duracells every year than all the Li in the world... Friends only wish Duracell on their worst enemies.
