I am planning to make automatic rechargable emergency led light (automatically lights up when there is a powercut). I scavenged led's from old emergency light. I planned on using this 3.7V 300 mAh battery . The circuit automatically goes to charging mode when there is power and switches to battery when power is off. Can anyone please clear these points for me?
- Can I use my mobile charger which is rated 5V 1A output for charging it.
- If so, the circuit is turned on 24/7, the battery seems to have overcharge and overdrain protection circuit. Will the battery last if the circuit is always on?
