Get a licensed electrician pull a permit and make sure that they are using the approved charging devices for your vehicle by cutting those corners you can greatly increase the risk of fire in your house

an inappropriate charger has the ability to overcharge that battery pack and when we overcharge a battery pack we're introducing too much energy into it uh energy creates heat

once these batteries uh become compromised uh they actually start an exothermic reaction uh heating up heating up continues to heat up and then uh all of a sudden they start off gasing which those gases are flammable uh once that happens now we have a propagating uh scenario where it it starts heating up all of the cells around it and now we have a much larger fire event on our hands
