Specify the model of your replacement cells so dump can be edited properly.

For bq30z5x we can update qmax of each cell

 Qmax is capacity parameter not the voltage 

 For bq30z5xx Safety, Protection, Charging and Chemistry profiles should be reprogrammed to use 4.20v cells instead of 4.35

 for bq805x Sanyo Tools should be used instead of bqEVSW tool
