There were a few Discarded Mobile Phone Batteries lying around the house, so I was thinking how to use them as they had plenty of juice left in them to run something.
This is how I could find a use for them by making an Emergency LED light.
Step 1: Parts you will need.
33 LED’s of 5mm.
One LED 1 watt.
A thin PVC sheet to fix the LED’s.
An old PVC light case.
3 Discarded Mobile Phone Batteries of 3.6 volts each.
1 single pole double throw switch. (SPDT)
Wires, solder etc.
