I need to design a Li-Ion battery charger. Many of the Li-Ion battery charge controllers have an option of choosing 4.1V or 4.2V charging voltage (times numer of cells, if needed).
cathode (?) type. Can anybody help me answer following questions:
- How important is this voltage value?
- How to find out what kind of battery is being used in the instrument? I asked Microchip (they make MCP7386X I seem to like) - have not heard from them yet. BTW, has anybody had issues with MCP73862/4? Thank you!
