This is embarrassing but, I can't find an answer anywhere...

I have a DALY BMS 4S 12V 100A with only the NTC and Balance Leads ports. Nothing else. I have no clue how to connect to the device and set the amp hours of the cells or the sleep time.
I was able to do these settings on another DALY SMART BMS 4S 12V 100A W/ BT.
I'd like to check the old (non Smart) BMS' config and adjust.
Thank you in advance.

This is an easy answer. It's set at the factory, and you can't adjust/change it to the best of my knowledge. That's why the call them a "dumb" BMS.

Thanks John.
It's good to know that the settings don't have to be changed by plugging my brain into the hive mind of Daly... ick
Any idea what those factory settings are on this Dumb 100A BMS? Not super important since I can't change them. Just wondering.

I think it depends on what chemistry the thing was set for. I know Daly defaults for their smart BMS are not ideal. You could try asking Daly, but I wouldn't hold my breath.

Okay. I think I'll just hold my breath and watch the readings on my ISDT BatGo balancer. Perhaps I'll be around when it cuts off so I can note the voltage.
Thanks again.
