Charging several battery packs at once

Charging several battery packs at once

Are there ways to charge more than one battery at a time? Answer: Lithium battery chemistry is volatile. If one battery can catch fire and cause a lot of damage because of improper charging, imagine what several batteries hooked together and charging in close proximity to one another can do if anything goes wrong.
