Thought it worth bringing up, The new Daly BMS (200A 16s) I had connected to some batteries several months back was activated and appeared to work, I checked the voltage on the output and it was the same voltage as the batteries, never tries charging or discharging, had nothing to connect to it.
I did find that the BT APP was set to sleep after 10 seconds, was a real PITA to change this in the app as it wold close before I finished typing the password, anyway got through that and changed it 30 seconds then to 3600 seconds etc, I realise I could have just plugged it into the computer and changed it there.
Main reason for this post, after building the charge controller I then wanted to connect to the battery bank through the BMS only to find no power at the BMS P- output even after activating the DALY BMS using the switch on the BT dongle could see all the details on the phone app but could see the charge and Discharge moss was turned off.....WTF!
After many attempts at trying different wake up methods, most of which would wake up the BMS still did not turn on the mosfets, connected to the BMS with the PC software and could see in the bottom left corner a small message in red.......I guess that's the answer.

So I tried the 2 pins by shorting them with a switch and the mosfets switch on, but it want the switch to remain on or the fets will switch off again.....why they change this?
I did like the way the old ones worked with out the need for the switch, Having to use this switch might be very good in some situations as it makes it very easy to turn the power off ans stop everything, then its a good option to have.
I think this can be changed with a command using the PC software but haven't investigated that yet, apparently this is customised.
Some links with very little information.
