Li-Ion batteries are very useful, but dangerous products, if we do not pay attention.
I will show you a simple method to protect your existing 18650 Li-Ion batteries. And all for 40 cents!
We will build protectors which:
- Interrupt charging if the cell voltage is above about 4.2 volts
- Interrupt discharging if the cell voltage is below about 2.5 volts
- Limit the maximum current to a few amperes
- I show you in detail how you can integrate protection boards in the battery itself
