DALY Smart BMS 16S 48V 250A LiFePO4 with WiFi Bluetooth Module CAN RS485

Cumple con todo lo que dice

Typical bait and switch Chinese product. Clearly shows a Wi-Fi module that also provides Bluetooth but the dongle they sent is only WiFi. A Wi-Fi that connects to thier cloud serves that is down 90-95 percent of the time. Without Bluetooth or WiFi there is no way to setup the BMS to your system = brick. They casually sell the item they were supposed to supply for another 17 dollars and 30 days worth of shipping. They do not reply to any emails or requests both through Amazon or their website. Will no longer buy Daly for me or my customers.

No tech support help for connectivity issues, otherwise it’s a good product.

I have 5 of these BMS on a 71kwh of batteries for 13 months and they are all still working

These are a lot smaller and more expensive than the earlier models. Sometimes that can be Good I’m not so sure in this case.

Error in voltage measurement after ONLY 2 DAYS OF USE It only worked for 2 days It was installed and after two days, it started to measure incorrect voltage values, in cells 10, 11 and 12. With voltages of 4.8V, 2.1. 3.9 V But after measuring with the voltmeter directly in ALL the cells of the battery bank, all the cells have their perfect voltage. 3.334V. Even the voltage is correct at the terminal of the cable that connects to the BMS I tried everything possible, reset, restart, reconfigure, turn on and off, but nothing. The BMS continues to measure incorrect voltages It only lasted 2 days

BS! Same number as the original but when it came in it was a mini. 👎🏽china buy American 🇺🇸
