Ok thx for the info on the cell,

It do run when setup on automatic 78% , but will hit the cut-off, but running just one 4S is fine, no matter wich one i use...

Is there an easy way to test the amp on the cells?

we tested to reverse the wire, controller, nothing worked :(

thx

Hi,
You should be able to read the max current from the software use to set the parameter of the controller. b2 setting should be set to zero.

Check (or replace) whatever series adapter/connector you are using.
