What is the safest way to use lithium batteries under high load ?
I want to use a couple of 18650 protected lithium batteries (3.7v 2500mAh) to heat up a little bit of nichrome wire (0.16mm, 50ohm/meter). I’ve read that if I use those lithium batteries they might explode so I would like to know what is the trick because I’ve seen them being used with electronic cigarettes and portable tobacco vaporizers which use nichrome wire.
Li-Po can vent to flame of abused. No lithium likes to be dropped, Li-Po is the worse.
If you keep your batteries cool (peltier junction perhaps) you can pull a ton of current.
