Newb ebike dude here. I have a couple of 13ah lithium batteries to maintain on my new bike. My garage is very hot in the summer and very cold in the winter. Not the best place to charge or stow batteries. Which leaves me to my radio room where all my electronics and radio (ham) stuff is. I have a large ammo can, and is it safe to store and or charge a battery in this? I don't really have another choice. Is storring a battery inside your home safe.
