Lithium Pack Troubleshoot CC Onward

[Bigjmain]

Hi, I have a stock lifted CC onward (13hp motor from factory)with upgraded 2g cables, alltrax 500 and 400a solenoid. I just pulled my lead acid batteries and connected up my lithium pack from extreme carts. It uses an ant 200a bms and pouches. I think resembles a leaf pack everyone here is building.

When I first started using it I had to ease on the throttle or it would trip the pack. Now, it is tripping the pack fairly regularly... I tried to lower the alltrax all the way down to 200 amps and it has no effect on the tripping.

Does anyone have any ideas on what it may be? On a side note, the guys have been great it is just difficult to troubleshoot over the phone and they are an hour away. Trying to get some feedback here before making the drive.
