Yes, i set it to 3 deg C , stuck the probe in ice water and it worked as it should. Tried a couple of warmer temps and it worked there also.

I have been playing with the 12v 280ah battery pack without a BMS (while sitting there monitoring it) for several weeks. Learned a few things during that time. It may be obvious to some but here is what i learned. 1. The bus bar connections between the batteries and cables to the inverter are...

I am new to this forum and lipo/bms but not to electronics. Just updating this year old thread to help other like myself get information faster. Building two battery packs using the Daly smart bms i have determined the low temp cut off does work and can be set with the app via Bluetooth. I...

I have one correction my Bms is a 200 A model.

Maybe order online from HF

Yes for sure, the temperature probe is displayed on the app so it ahould be easy to monitor.

I had a Hall effect device and a shunt hooked up in early testing and all three were fairly close in value. For the SOC meter i cant say. When first used the BMS, the SOC meter was way off on one of the BMSs 75% vs 100% (i am building two packs) with similar battery voltages. Contacting Daly I...

I have been building a couple of packs and bench testing them for a while. Running them with currents in the 20 amp range everything seemed to be ok. Only when the current draw got higher 50-80 amps did I notice the terminals heating up. The problem was always the bus bar connection. But like...

I drilled mine for 5/16-16 and used a bottom tap. Secures with locktite assembled the buss bars with bolts. Minimal voltage drop (.001v) between the terminal and buss bar pulling 175 amps.

My batteries have been in storage for a while. Yesterday I decided to check them and found the no data bug. The reason I am posting is because there is a little more to the puzzle. I have two packs with Daly BMSs. One works fine with the smart Bms 2.1.0 and the other doesn’t, go figure. Using...

I finished building a 12v battery pack. My target max current was 100 amps so everything was oversized for some headroom. One of the challenges was voltage drop across any connection. If you measure the voltage drop from a connection point to the terminal or wire connecting to it you can...

I think the sum volt high protect is just a total of the cell high volt protect setting. It changes with the cell setting. Maybe its a place holder for a future upgrade.

I need to return a BMS to Chargery for repair. The Fedex charges of $145 (best price) are unacceptable as well as the paperwork involved. Has anyone returned a product with a better shipping rate and carrier? Thanks

I also agree, the batteries packs I am building are for my RV and you can see will not ventilated. Very much heat here would be a problem.

I have scrolled thru all the youtube videos looking for Will’s Review of the Chargely BMS. A link to that video would be most appreciated.

TY

Its from Harbor Freight. Everything fit very well. I padding around the batteries is repurposed shipping materials

It needs some charge current to activate. Charge through the BMS. After it activates your can remove the charger and it will continue to operate. The BT port will Shut Down after some period of time. The Shut Down Delay is controlled by a parameter in the Configuration menu. There was a thread...

I dont know. If works on a pc. You can do everything with the phone app

Converting my RV from flooded batteries to lithium. For cost efficiencies I am going to build the battery packs. It appears that A Class Calb cells are of good quality and cost is reasonable. The total battery bank will be 400ah. What I am pondering is wether to use 100ah or 200ah cells to...

Although this application isnt a solar project, it serves as a warning about cheep wire. This is 4 gage wire that came with a wench I purchased for a UTV. Its was cut from The center of a five foot section. The wire is about 1 year old and was never wet. When the the wench was trying to run, the...

That is exactly what the two i have do. Just put a load or charger on it and it fires up. Sometimes i just use a ohm meter between p an b leads.

Can you supply the UPC or part number for the case?

My system has a Daly smart BMS that shut down because of a low battery. As the battery voltage rebounded after the load was removed i used the reboot function on the app to reset the error.

I came across this app from Southwire in the app store to calculate what gage wire to use.

I just finished hooking up a 300 A Daly smart bms with BLue Tooth interface to a iphone. I ordered this BMS from the Daly Store. It installed easy and worked out of the box. There are so many options for communications I believe each one has a different firmware set. So carefully look at the...

Using a Daly 200A smart bms I have drawn 180 A for 5 minutes. As with most bms systems the output wires are undersized for the rated current. In this case they started to warm up. My suggestion is to derate the “marketed” capacity by 50%
