Hi Aaron,
Yep, periodically checking terminal bolts/screws for correct tension is something I do over the complete system, especially high current connections. You could write a small book about the myriad of pathways that lead to loss of connection integrity.
An added problem that I have is caused by the "clowns" who tapped the cell terminal posts, they did not tap all of them perpendicular to the post surface.
DALY apparently use 3 different types of chip sets in these devices depending on the configuration.
The trouble is the web site, it has so many pages for the same looking device with bad English interpretation, it's so utterly dumb that you can go around in circles trying to actually confirm what configuration the one you are looking at actually supports. Especially if you are new to this and not aware of the Chip set lottery.
This is the link I use, the BMS has parallel port, CAN/RS485, Key and DI/O with optional addons like Active EQ and Parallel balance.
DALY Link
I also order a couple of RS485 to USB leads from them to connect the Balancer and BMS via their RS485 com ports as it can wake the BMS from PC software connection activity, the standard UART port cannot, that also leaves the UART ports available for the DALY Bluetooth dongle if required.
BTW thanks for that link, I found his tear down and hack of the BMS about 3 weeks ago
