I have two JK B2A3-88S20P BMS for last nine months or so, and working fine both on the kitchen table, no inverter, and. in the RV all hooked up.

Now, I just received a new BMS, B2A8S20P, and have connected it up, in the kitchen, no inverter or other equip, just the BMS and I receive a "Discharge short circuit"

There are a few settings on this BMS which are not on the other two the 3-8S ones. If I turn off the page 3, the "Discharge" slider, the error goes away. There is no load on the battery, except for the BMS. All the cells (4) are sitting at 3.3, and within .001 difference from each other.

I don't understand why I am getting this error, and have read about all sorts of forum posts and still can not figure it out.

Help understanding this is appreciated.

Thank you.
