First responders urge tech be used with caution after RV fireBATON ROUGE — After an R.V. in St. John Parish was destroyed in a fire, killing an elderly man inside, fire responders urge people to pay closer attention to their electronics. Lithium batteries are in all kinds of electronics, bikes, scooters, and phones, to name a few products. Chris Carson runs E-Bike Baton Rouge, selling electronic bikes and scooters, all of which use lithium batteries, a kind of rechargeable battery. Cheaper products, Carson said, tend to have fewer certifications and protections.
