Hey guys!
I´m finally experimenting with real battery and electricity projects after a long while of learning about it from a theoretical point of view!
I´m aspiring to set up my own off grid power. But naturally I´m starting small, so I just recently got myself 3x NCR18650Bs to power first and foremost an LED strip. The LED strip is 12v.
I have 3 points that I am wondering about, where starting from 1 is my main inquiry!
1. I had a small accident while all the 3 batteries where connected and it short circuited for about 2 seconds. The only apparent damage was that the rubber of the wires partially melted. But I was wondering if there could be potentially any other damage done to the batteries, that I should take into account? What do you think?
2. And regarding the set up for the LED strip - I was wondering what would happen to the battery if I hooked it up to the LED strip alone. I mean not the 3 in series but just one of them. Obviously the voltage would be too low to run the LED, but would it harm the battery?
3. Last thing that puzzled me a little bit. After my experience with short circuiting, I was wondering why don´t the batteries short circuit when I measure it with the multimeter. I figured it must be because there is a resistor in the multimeter, or the multimeter functions as a resistor in itself (I don´t know what would be the right terminology here) - so it led me to the question: Could a battery potentially short circuit while being hooked up to any sort of appliance? Say if the power of the battery is too great for the appliance. Or maybe it would simply just blow like a fuse, either the appliance or the wire?
Any feedback would be greatly appreciated!
Cheers!!
