HBL2360 motorcontroller short fault

Hi!

We are using the HBL2360 motorcontroller to power two motors of 24V.
We connected a battery of 26V and it worked, the motors were spinning at every throttle command.
Than we add some batteries to increase the voltage to 50V.
Now the motors are spinning very slowly and they won't go any faster, than Roborun gives an short error and the motors stop.
We don't know what couses the short. The wires are nicely sealed so that is not the problem.
The logged data is in the attachment.

Kind regards,

Bart van den Beld

Hoi Bart,

What kind of batteries are they? Do they have enough amps? Both of them? And the connection is done with thick cables and proper connectors which are tightened well? I guess there's an issue in your powerline to the batteries or the batteries are not good enough.
