Bypassing Battery BMS

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.

Check first with bypassing it, if it still cuts its something else.

Otherwise im running this Daly Blue 150A bms with 65220 motor reaching 3,6kW on 14s5p config.
But Battery Amperage is much lower, therefore 150A is enough.

I run without bms and use the flipsky 75200 max current settings with a circuit breaker in the current path. No problems after 3 years. I charge with a bench supply and an active balancer.

Thanks for all your responses. I bypassed the Bms and set the battery amps on the vesc to 50. Did a bench test and vx3 pro is now stopping, at 50amp not cutting out giving me about 2.3kw on the 13s6p.

Water test later.
