OP-AMP lithium cell sensor

Lithium 4 cell sensor with high impedance sensing using op-amp. 
First I am using a op-amp as voltage follower  
to minimize measure current through the cells. Afterwards another op-amp is used as diferentiator so that each cell voltage is measured with gnd. as reference.
The use is for arduino ADC input.

What do think about this layout, was a meditative task 😁 http://everycircuit.com/circuit/4806980312236032

Nice and clean. :-)

The difference amplifier are a bit large splitted, mean the voltage divider are far away, but all in all it look clean. Thanx @santos5151 for this little layout practise 😁
