Thanks, that did the trick, could be a solution that Daly would sugestHave you charged it with > 10A? Mine wont startup until i do that.
Does it really need 10A or more? I’d heard you have to connect a charger before the BMS will wake, but didn’t realise it needs so much current!Have you charged it with > 10A? Mine wont startup until i do that.

Ive only read elsewhere it needs >10A. When i first started my BMS, i kept turning up the voltage (getting a little worried) and it sprung to life around 10A. I just tried it again - 7A was when it sprung to life. Thinking about it - i suspect it senses a deltaV as how can it measure current when nothing is flowing.
A piece of wire shorting the B- and P- has also worked.
Thanks guys. I guess it makes sense that a short circuit appearing across the input leads would cause the BMS to wake up, because if it were fitted to an e-scooter fleet and a user comes along and hits the throttle lever, that’s going to present a short to the BMS at which point it’s going to be expected to provide some power. Maybe there also needs to be some kind of current flow in the right direction, as people have mentioned that a multimeter continuity checker will only wake the BMS when connected with the correct polarity, so the BMS perhaps needs a small potential difference.when i connected my charger, didn't even charge yet, the bms woke up
I’m also finding I can not adjust the “sleep time” setting. Has anyone successfully changed this to 65535? In the screenshot on the Daly website it shows the battery type has been set, but although I see a picklist, I cannot set battery type - maybe that’s related to not being able to set the sleep time?I can't give up more than 3,000s
You need an NTC thermistor connected to the correct port on the BMS, otherwise it will not work (as you found out).Hello everyone, I'm a new member and this seemed like a good topic for my first post.
I have a Daly 16s smart bms. When I first connected it and did a power failure test I received a "discharge temp low level 1", and "charge temp low level 1" faults with a "num of temp -40". I do not have a temp sensor attached nor could I find a disable temp sensor setting. I did find in the collect board settings where "board 1 temp num" was set to 1, the other two were set to 0. So I set this to 0. The "num of temp" now shows 0. However another fault popped up with diff temp level 2, and the other faults went to Level 2 as well. Just on a whim, I set the diff temp protect from 15c to 0. This has no effect that I can see. However I am still in a position where I can't use the battery without the bms shutting it down due to these faults. Any help would be appreciated.
