ECO-WORTHY 48V 100Ah 5120Wh LiFePO4 Server Rack Battery

[BarracudaBob]

I suppose I could move the antenna but I prefer the RS232 connection. Much easier for software development as it eliminates the BLE layer

I'm not a big Bluetooth user but if I crack one open I like to do all the updates.

I do have to admit now the range is much further and I had one outside on the porch dumping into a pool cooled dummy load that I was watching it from my easy chair inside via Bluetooth

I don't think I mentioned this, but all 7 of my EW batteries came without bent ears or handles. They were packed with super thick black foam on the front.

That was one of the improvements they made by reading it on this thread.

My system shutoff at low voltage cutoff at 48V despite my soc via smartshunt showing 19%. As thats basically a 5kWh equivalent in my 25kWh config and having had cat turn off my gokwh rack mount that was my first thought. Sure enough ecowrthy was sitting pretty in 70% soc while the other batteries were at 48V. But it wasn't the power button cat had turned off, but the breaker. Turned that back on and away we go. Did show an ODC warning in the app which is understandable with big discharge going into basically empty 20kWh of batteries, but didn't shutoff or anything like that.

Connect the windows software Read it and send us a screenshot that's where all the good info is. I see an ODC alarm. If I had the gas it's over discharge.

Some of these smart BMS is coulomb counter can cause trouble especially if they're not calibrated they'll shut the pack down even though there's plenty of capacity because the counter says it's empty but yet your SOC has plenty left according to the meter.

Charge it back up to 56.8v or hire and that'll reset your SOC hold there for 2 hours let it balance.

If you haven't done so already connect the window software change the balancing to idle 3.42v. And 10mv deviation

Yeah the soc on the battery was fine, just with the breaker off it couldn't discharge overnight along with the other 20kWh as I was trying to start the day nearly empty to try for new record. Basically just an example of connecting a decently charged battery to a bank of empty ones, I see some people spending a lot of time getting voltages within 0.5 volts etc before paralleling packs, just an example here where one doesn't worry about it. Sure there's a high drain there with over 70A initial discharge but it settles down quickly.

I charge everything up and connect all the batteries together at 100% fully charged.

I am a firm believer in my top balancing method and then deep discharge, charge back up, deep discharge, charge back up, and it is ready to go never think about it again

I just finished an old DC house that I had laying around since December. Cycle that a couple times and it woke right up everybody's balanced up.

Concept works for everything that I've ever touched. Only wish I knew about it two years earlier

More experience data. All 7 batteries have all cells within 15mV of each other to 100%. I have done one discharge to 5% (my load cutoff, may change) without cell delta change. So far, pretty happy with these.

You did your home work in the beginning and now you can enjoy your hard work. Hit 56.8V for an hour or more per week and life it good

What have I done with my brand new battery........

 

[BarracudaBob]

I just fell out of my chair That is something that I would do. You have to have a little fun

I found a max cell setting of 102 to 104ah keeps the coulomb counter honest for a Victron Smart Shunt 100ah discharge.

Gotcha!!! I wrote an EW Battery Emulator so I could change data and verify it changes the correct values in the EW Software. The EW Software is actually talking to my emulator and I have pretty much mapped out most of the data including a number of "flags" or "bits" and what each indicates for a protection or alarm fault.

I knew you did something special. I have never seen all thoes alarms. That if Fricken Bad Ass!!! Send that to tech support they would pass out!

What brand of Scotch do you drink? Unobtanium ?

So you got the protocol or reverse engineered? I want this protocol real bad.

 

[marionw]

The EW battery via the RS232 port on the Master is working (mostly) using the Modbus-RTU protocol.
The device addressing it a bit different than normal Modbus-RTU as you can pull data from the Master (as Master) which is showing below which represents the entire battery stack/bank and then also pull data for each individual battery

It's amazing that they don't have an app that does just this already.

 

[BarracudaBob]

It is evolving before out eyes

 

[BarracudaBob]

I try it so you don't have to

 

[BarracudaBob]

The display isn't functional. Something must be missing on the mother board or data pins reversed. I'll have to play with it a little more. The plug on the BMS did say for display and it is a UP series smart display. Sure would look nice if all cut out and working.

 

[jorby]

I can see it now, a CNC service to cut out and drill front panels for the display and antenna....
