We first tried the short circuit method to overheat the batteries and hopefully blow them up but it did not work. So we lit up the batteries using lighter fluid, that smoked up the batteries nicely. The portable fire extinguishers used were able to calm down the initial white smoke coming out from the li ion batteries. We did not get any big flames in this test but we can imagine the mini extinguishers will not be able to handle anything more than the white smoke.
The takeaway is that having a portable fire extinguisher at least gives you a chance to salvage your vehicle in the early stage during the white smoke stage. If nothing more than that, it at least gives you some time to run for cover and stay safe.
