Such a great quality on this product, correct in size and very functional, a great product and fantastic price

Muy útil ,cumple el objetivo para lo que lo compre . Excelente calidad .

Made sure I hooked it up exactly as instructions specify and it did come on. But does not remain BT avail. Making you wonder if the balance also went off line with BT. This is too costly to just leave as a paper weight so this so sent back. I find meters that measure battery information often come with balance ability. I find it much easier to buy one for each of my wall battery units. Seldom need them. They balance very well on their own.

So let me start by saying this bms functions well does what its supposed to do well and what not. My gripe with it really comes down to not really much to do with the way it functions but rather with its design. Firstly lets start by saying this bms is big and by big i mean its atleast double to triple the size of an ant bms and in the worst way possible, its thickness. I posted on my facecbook about this issue and someone more knowledgable then me about battery tech told me the bms is big because the mosfets used in this bms are cheaper ones that heat up a lot and they add a ton of metal in the form of heat sinks to combat this but the problem with that is then the bms is releasing tons of that conducted heat into your battery pack if your sealing this into the battery pack and the fan doesnt help much with that either. The fact is this the ant bms uses much higher quality mosfets and therefore is much thinner because it doesnt have to worry as much about shedding tons of heat generated by cheap mosfets. That being said its easy to see why people choose daly sometimes over ant if you simply look at the two side by side the daly looks more impressive to someone that doesnt know much about this stuff yet while the ant looks like a cheap metal box basically but this is the furthest thing from the truth. My application for this bms was going to be a battery for my surron electric dirt bike but i cant use it for that because of its size which really i my fault for not making sure and chceeking that before buying. The surron has very little room to expand on battery capacity so using a bms that takes up more room then it really needs to do is not a option for me. The same guy that informed me about the downfalls of the design of the daly also suggested i can use the bms as part of my charging station solution which is a good idea but then i loose a lot of the safety features you get with running a bms and running no bms on a 72v 50+ah pack is a bit crazy to me and nerve wrecking. Im a bit hesistant to do that route but i really dont see me having any other option, i cant afford another bms and i already was trying to build this battery on a extremely low budget and already had to resort to using recycled cells which is something i didnt really want to do but dont really have a choice financially. Anyways back to the bms like i said at the start this bms does everything you want a bms to do and then some so if size isnt a issue its still a great solid option but if size of your battery packs is something you need to keep at minimum and the bms needs to be mounted to your battery then i suggest not going with this option and going with a ant bms instead like i wish i would have done now. I really wanted to like this daly bms as i have heard great things about them from the diy solar guys but it would make sense they would like these and the ebike guys wouldnt since diy solar guys dont usually have to worry too much about working with limited space.

I ordered this product because I am an DIY'er I build my own batteries. Only draw back on this item was that I did not notice that it did not work with Android or Windows, Only IOS have access to Bluetooth settings of this BMS. When you are ordering make sure you read the description carefully.

Connected to the app instantly when you push the little button on the Bluetooth module. Could get right in and change the settings for my system no problem. Better instructions and an up to date “smart-programmable-active-capacitive- balancer/equalizer” would make it perfect. However Daly makes one of the most affordable, high current charge/discharge BMS’s you can buy, so you’ll just have to augment it with a third gen NEEY balancer if you want the best system you can own.

The Daly 500A smart BMS is exactly what I needed. It came with a Bluetooth dongle so no need to buy a separate one. The JST style distribution wires were a bit on the short side though. The company is very responsive of you need anything. I’ll buy from them again.

New daly smart 150a bms (Amazon) on a new 12v 4s Eve LF280K battery build from Jenny Wu @ Docan. The review is about the bms and it is working awesome. Cells were out of sync after delivery but not by much. The smart daly bms with a fan has built in cell balancing. Daly balanced all cells during first charge leaving only a differential of 0.001 volt on one cell. Should be able to correct that difference during the 2nd charge/discharge cycle. I’m impressed at this device as I was used to(3) 100 ah Renogy smart batteries that all the cells were never completely balanced during the year that I owned them. Renogy sucks and I know that after spending way too much with them. Well anyways back to the daly talk…after charging my homemade eve lf280k build with the daly it was balanced to a difference as i said earlier to 0.001 volts. I’ll update my review if it starts acting up on me. But for now Im extremely happy to have used daly’s smart 150a with built in fan. I’m under the impression that the earlier daly bms models didn’t have built in active cell balancing and low temp protection like the one I just used in my build today. Anyways hope this review helps you. I added my parameter setting screenshot to help you get started.5/12/24: Bluetooth not workingSometime in the last week the Bluetooth function has quit working.Installed new Bluetooth7/21/24 Smart bms 150 quit working all together so I had to buy a new one. This is DALYS last chance with me. When this one goes I will never buy Daly products again!!!!!
