Customers say
Customers find the BMS to be a quality product that offers good value for money. However, the functionality and voltage accuracy receive mixed feedback, with some reporting it works well while others could not get it to function and experienced incorrect voltage measurements. Moreover, the app quality is negative, with customers describing it as spotty at best. Additionally, the balancing function and ease of installation also receive mixed reviews, with several customers reporting issues with the battery shutting down completely.

Worked great, although the app and BT broadcast can be spotty
Bluetooth communication can be spotty, but it’s got a good distance for connecting. I replaced two BMS units in a pair of 100Ah lifepo4 batteries. One had died after a year, the other battery had been DOA. After replacing the original BMS with the Daly bms, both batteries were able to charge fully, and the cells balanced. I am able to use the app to specify *most* of the values it is supposed to change, and connection *usually* is quick and painless. This is where it gets it’s 4 stars, not 5. The app isn’t very straightforward when it will or won’t actually change a value, but the important things (for my usage) have been changeable. When it doesn’t want to broadcast the BT signal, I noticed you can force it by hooking up either a draw or charge to it.It’s worth what it costs, and if you’ve got a dead lifepo4 battery that you know the cells aren’t completely destroyed, it’s worth trying a new BMS.

Avoid, doesn’t work, app is terrible
This bms does not work well. It read incorrect voltages, so i kept undoing and redoing the wires, thinking it was my leads. I finally got fed up and ordered a different brand. The other brand has no issues at all. I had used Daly in the past with success, but it seems like the quality has gone down. The app changed as well. The app has always been garbage, so no change there, as it’s still garbage. Inconvenient to install, settings are hard to change, if you do get the setting changed you have to hope the setting sticks. The WiFi and Bluetooth adapter is almost a joke.

Works just fine.
I bought this in hopes that it would fix the bad 12v 100Ah LiFePO4 battery that I bought. It solved the problem. I had charged up the near dead cells with a power supply. This BMS brought all the cells up to there fully charged point and balanced the entire battery.The only thing, if I had known 100 % that this was the fix I would have bought the version with the remote readout.Good product, it is working fine, I been checking it every few days since I installed it. Now it’s time to seal up the battery pack.Recommended!! Good buy.

Bastante sólido y bien armado
Tan pronto lo instale estaré opinando, mientras tanto puedo decir que sobresale la buena configuración y montaje de los componentes.

lifpo4 12 volt BMS
I am using this to balance 4 lifpo4 cells at a time. I can charge 4 cells with my bigger charger. Saved me a lot of time.

Quality issues
This is the fourth Daly BMS I’ve purchased – but it will also likely be the last. The first BMS was for a 12v system, and other than not having a good balancing function, it worked as expected. This led me to purchase a 24v and a 48v unit – and those have both been disappointing. The 48v unit died within a week and was replaced. The 24v unit jumps around on the voltage, which can cause protection to trigger incorrectly if you get too close to the charge / discharge limits. Neither have good balancing either.I purchased this unit mainly because of timing – I wanted to get a different brand, it none would arrive in time, so I took a chance on this one. At first it seems greatly improved – better balancing, and more accurate voltages – but now it has started briefly registering incorrect voltage on balance line 7, causing the whole battery to shut down. Warrranty process so far has been ineffective and frustrating – sorry Daly, would not recommend.

Absolute trash. Do not buy. Bought 4. 2 are now bad after 35 days and 1 connector has failed on a third one.
