I had an
150A, 1A active balancing BMS.
And was happy puppy all the days that it worked!!
I really liked the idea, and waited several weeks for development to finish.
Sadly many Chinese tend to do QA testing in the field, by too early release...
From the fist batch (including mine), all got returned.
Several others have bought the updated version, and now it's a stable BMS.
As compensation I received the 1A active balancer for free when purchasing Daly 250A (smart was not yet released)
The Daly lasted almost 3 months, I received refund from Daly after returning......
To keep a long story short, the active Balancer is now my main "BMS" for about 140 days.
With it active balancing and my "perfect installation skills" it keeps all cells in pace.
I do feel the need to check several times a day to monitor my cell voltages is I'm personally the stop/start switch......
I'm now building the DIYBMS, that takes its time.
Mostly due my location, rural Thailand.
Hard to find parts local, and AliExpress is since Covid 19 exceptionally slow.
Even over 3 months to deliver parts.
I really liked the active balancer BMS, short but impressive.
The app is straight forward, easy to use and understand.
I like that it standard does cycle counting and SOC % estimation (it have shunt internally)
My 150A Daly smart...
Never even got to installing the app.
(I hope they updated that installation process)
It's eating dust now.
It "works" but needs me to pre-charge my inverters..
Something my wife and children aren't able to do.
It was supposed to work along side of the 250A...
With current quality issues of Daly, I doubt it could last long..
If the
active balancer BMS would have been good at the start, it would have saved me tones of money and time..
In the last month's I learned a lot, and will have (once all up and running) 3 sections with my 80 cells, 48 X cell modules each capable of "balance" 850mA (dump load) (with heatsink up to 1.5A)
WiFi and open source.
Adruino skills are a pain to start to learn, once finished it's handy for all over the house for smart automation.
