Bypassing Battery BMS

Build, Repair & Mod
1

My project going well and I have now carried out a couple of water tests using Aliexpress batteries.

Issue I currently have is system seems to shut down after about 5mins of continuous use. I have been monitoring the temperature on the VX3 pro and my vesc has never reported anything higher than about 38 degrees so I suspect its the battery BMS.

Was thinking of bypassing on the discharge and control max amperage on the vesc , thoughts ?

It should be fine for a few tests the BMS is more important for charging to balance the cells. I bypassed mine for a few sessions thinking my BMS was cutting but it was my max watts setting in the VESC.

If you have a smart BMS you can check the logs. That will tell you if it detected an overcurrent.
