Are these cells of the same technology found in laptop batteries ? I.E. can I use these cells to rebuild my laptop battery ?

GND seems not very well designed: it is connected with GND comming from Arduino. Current returning to power supply will use this path if GND is unconnected on power connector J3. Small copper traces will literaly burn, acting as a fuse.
And GND trace width and route is not very straight to JP3. It will not be a problem at some amps, but with both drivers on at 30 amps….. :-(

Nice board, but limited to 5V motors. Having separate Vs will allow up to 46V motors.
No public wish lists :(
