Change battery meter behavior
For starters your device needs to be rooted ( see rooting ) 

One way could be to fool the system by pretending you have a smaller mAh capacity battery so that it stops charging prematurely (relative to actual capacity) but that's tough because the battery capacity files are hard coded into the kernel, so you need to "cook" your kernel. See
 Where are the battery capacity files located?

Practical alternative is to stop charging at a level that matches your desired voltage.


You can do it the hard way. See
Automatically limit (stop) battery charging at a given percentage


Or 


Easier way. See How to limit charging to 60%


Also see Ideal charging / discharging percentage for maximum battery life?

Rather than actually figuring out the voltage levels at which you want to charge / shutdown , it is easier to go by battery charged level and stop charging
