Battery Charger Schematic

I have to create a wall charger?
I am going to produce a battery power using 4 AA Rechargeable Li-Mh 2460 mA batteries.
These batteries come in series such as the picture proven.

I must understand what the easiest method to charge them could be.
If I must produce a new charger would you incorporate a schematic and so i get sound advice.
would this be considered a good charger?

I’d obtain a lower current charger which has thermal control.
Creating a charger on your own is a touch complicated for NiMh cells.
You’ll need a minimum of a wise controller nick and driver transistor.
