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...

Fingers crossed someone with good knowledge shows up, but I’d suggest also using the advanced search function on the forum to see what people have previously said about CATL 302. My guess would be they should be fine as CATL is a well respected manufacturer, but you never know!

No, I‘m in alibaba chat with Quaine Xiang sales rep, but it says it’s 1:56 am local time there so now I’m feeling guilty like I should leave her alone and come back during their daytime ? I’ve never contacted Cassie and wouldn’t know how.

Take one solar panel, connect it with a cable to the inputs of two PWM solar charge controllers in parallel, then connect the outputs of those controllers in parallel to one battery. So one panel, one battery and two current paths between the two, via two different charge controllers. Leaving...

Yes, I just ploughed through the whole “news” pages to see what I could pick up. The link was posted by @asder in post#34 of this thread The second link should be as follows: http://dalyelec.cn/daly/Manual.pptx (I messed up by including the same link twice in my original post above, and no...

It’s completely normal for a Daly BMS to behave like this - not a fault at all! The BMS will go into “sleep mode“ and switch itself off so it protects the battery against further discharge. When this happens the voltage at the P- lead will float and the voltage reading you see on your voltmeter...

Maybe you already realised, but you can adjust the shunt values for PV and Batt within the ADC menu, so if you establish that the SBMS is over reporting PV current by 12% (for example), just reduce the PV shunt resistance by 12%. I will be checking this and adjusting mine too. Also, hopefully...

I concur. Using charging direct to the battery terminal with iCharger I see no balancing occurring on the BMS, whatever I do with BMS settings. Even enabling “balance on discharge” doesn’t help, which seems odd to me.

Awesome, thanks (y) I bought my Daly 2 years ago but only now starting to use it!

I haven’t read the whole thread, so sorry if I am repeating what others have said, but is overcharging of the batteries and venting of electrolyte gas a possibility? Gas boiler ignition clicks on and ignites the accumulated vapour?

I guess they say to connect it when the battery is empty as the monitor needs to learn the battery capacity by observing a full charge. These lithium batteries are so hard to measure just from looking at their voltage alone, as the voltage changes so little as the battery fills up. So I guess...

I don’t want to be Mr negative, but I’ve watched an awful lot of Robert Murray Smith videos on YouTube, and although they’re entertaining, thought provoking and educational, I‘ve yet to see him demonstrate anything which is practically useful. Why do I watch his videos? Because they are...
