DALY BMS 16S 48V 100A LiFePO4 PCB Protection Board with Balance Leads Wires 3.2V Battery Protection Module Smart BMS for 18650 Battery Pack 48V with UART

Works greate. Nice value.

I live off grid and use this for my solar and it works perfect no problems. Very happy with everything would definitely recommend this to everyone

It’s cool. Bluetooth has fully adjustable settings. My 48 V golf cart with High speed motor can surge up to 190 Amps. I got it to trip the protection feature at 250 amps with six adults on the cart. You just open the app and reset the bms. Super easy. I have 48v 16 cell lifepo4 prismatic 120amp battery. Use the heat shrink connectors.

I have the 16s 250A Smart BMS. Everything was working fine for 4 months and the bluetooth disappeared from the app. I tried many fixes I found online but nothing worked. everything else seems to be working but I can't see the individual cell voltages anymore. No way to see what's going with the battery. I contacted Daly through the amazon messaging and have not had a response yet. This bluetooth issue seems to be well documented within the DIY Battery community. I hope I get this solved with Daly. In the meantime anyone reading this that is considering building their own battery pack, I suggest looking further as I am aware of BMS's that have a better track record than Daly. Update: I have had back and forth with Daly support. The support is TERRIBLE! I have only used the BMS for 4 months although I bought it August 2021, so they will not warranty it. They require pictures of me working on the BMS as instructed by their support department BUT they do not read what I write to them describing my problem. The communication is poor at best and they don't seem to care at all. I say steer clear of Daly brand BMS, they use poor quality parts that fail, they don't balance very well, the support is poor and there are MUCH better BMS companies with better technology. Boo Daly!!!! Boo!

it won't full charge and the state of charge is always wrong. I am using LIFEPO4 batteries. They do not need a float charge. I set the float to 58.4 and the cut off to 58.4, but it always stops charging at 54.7. The state of charge it displays is worse than useless. at 48.9 volts it displayed 56% charge when it should be 13%. I've learned to ignore it's state of charge and only look at the actual voltage instead. I deeply regret having purchased these.
