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

55.6 / 16 cells = 3.475 volts.
Using the ECO-Worth provided software (after you click Account and User login upper right of screen; password is 666888) you can adjust the "Balance Voltage" setpoint in the BMS. This is the voltage a cell needs to reach before Cell balancing starts.

Default Cell Over Voltage Protection is 3.60 volts, you do not want a cell to reach this as the BMS will stop further charging. You can set the "Balance Voltage" to something lower than what cell #11 is charging to and hopefully the BMS will start balancing that cell which should slow further charging for that cell while allowing the other to continue charging.

Some folks including @BarracudaBob have lowered this (raised back to default once battery has been conditioned) to allow the BMS to start balancing the cells that reach a higher voltage.

Before making any adjustments to BMS configuration or parameters "Read" them and then "Export" them. In addition as a backup take a screenshot of each page and save it as well.

I downloaded EW provided software and it was .rar file which had windows in the name. I don't have windows pc, but if it is the only way I can try to get one.
How does that software work? Do I have to connect with a wire or wireless is also an option?

With the V2 battery you can use an RS485 to USB converter plugged into the RS485-1 RJ45 jack or you can use an RS232 to USB converter plugged into the RS232 jack. Don't know if the phone app will allow you to change anything, I generally stay away form phone apps.

Low end Windows 7 laptops are cheap on eBay. Being able to monitor the battery with a lot more detail is great.

Running heat pump and and everything else is suckin' down my coulombs. Will P says let them go down so good time for them to get a bottom balance together. "it was a dark and cold day" Truly the dark ages that I haven't seen in years in sunny south Florida!

The predictions are CRAP too. Here is a 3.66K SW array:

No, these do not bottom balance. I said not to be scared to cycle your packs. Calendar aging larger factor than cycling degradation when used for solar.
 
I am not sure if the converters to USB you mentioned were something that supposed to be in the box with the battery. I didn’t get them.
I have ethernet to USB converter and will try that. I will also see if windows on VM works.

Thank you again!

I listen to you. I didn't try to charge them up at all with the grid. The sun came out and had one of the best days in January 2025 ever, solar wise.

I chopped the portion of my finger off today but that's another story. It was a wonderful solar day 🤣

I'm not sure if that's appropriate for the non-solar activities or not, but I'm okay.

Was it possible to reattach? Glad it wasn't more serious take it easy out there....

It's such a f****** stupid thing. I just added another row to my array. Everything went well. It was a good day.

We've had a excellent crop of vegetables and I was helping the wife chop them up. She had a new slide device where you put the vegetables on and you slide it and it chops them up. Well it worked too well. I got to the bottom of the eggplant before my finger is now called stumpy. If you're going to be dumb, you got to be strong.

Kidding but maybe you could detach an mc4 under load and use the arc to cauterize the stump?

I thought about that but I was already in the kitchen. I'll tell you what the best thing in the world is. Quick clot that and soaking it in a glass of hydrogen peroxide. That cup got warm really quick reacting with everything


So enough of that subject but this stuff is amazing. Put it in your medicine cabinet.

In have the balance Voltage set to 3.420 with 10mV but the cells are exceeding it. Is this for the "IDLE" or the "charging" setting? I just switched from IDLE to charging to see if it improves anything
 
I use a RJ45 Pin 1 and 2 that works for the LP4V1 and the E-W but @marionw if more familiar with the data deep dive than I am.

What is a good single RS485 adapter? I have so many multi units hard to find a single one that works out of the box.

That is correct - for RS-485 on an RJ-45 plug, the battery-in is lead B on 1 and lead A on 2 for the USB cable. For communication to the inverter, on the inverter side, it is B on pin 3 and A on pin 5. All pin numbers are counted from the non-clip side. This clip explains it well.

Why do you use an RJ-12 plug in an RJ-45 port? Do you use this for an E-W battery or the inverter?

I use the RJ12 (small jack in center) RS232 to USB adapter to communicate with my computer running the ECO-Worthy JBD software. Normally the RS485-1 and CAN are reserved for BMS to Inverter communications.

I have the V2 BMS installed in the original V1 battery so in my case the RS232 port is working. The RS232 port accepts both the JBD protocol and PACE protocol which does create more flexible opportunities for monitoring.

The RS485-1 port can be configured for a number of protocols for flexibility with a number of inverters. Some inverters may only support RS485 BMS to Inverter communications (no CAN) so the RJ12 RS232 jack would be needed for battery monitoring. I thought there was a post earlier in this thread where someone said they could monitor all batteries using the RJ12 jack.

Solar Assistant does not include the battery address in its command format with the battery so it can only communicate with the physical battery it is attached to. The JBD protocol does allow for battery address to be included in the command format, SA just doesn't use it.

So, If you can see all batteries in the stack via the RS232 port on the Master battery (might have to all be V2) and SA were to make minor modifications then SA would scan the batteries as it does with both the PACE and Narada (EG4 LifePower4 V1) BMS.

It should also be noted that there are a number of versions of JBD software out there:
a) JBDTools_ChangePow***
b) JBDTools V***
c) PC Software Tools_ChangePow***
d) MJBDTools V***
e) ECO-Worthy supplied version.

1) The ECO-Worthy uses the JBD Modbus-RTU protocol which does use the battery address in the command format.
2) The JBDTools_ChangePow_20241226.exe uses the JBD Modbus-Ascii protocol and does include the battery address in the command format
2) All others use the JBD Modbus-Ascii protocol but do not include the battery address in the command format.

Only 1 and 2 above fully work with the ECO-Worthy battery.
SA uses the JBD Modbus-Ascii format but does not include the battery address in it's commands so it can only communicate with the battery it is physically attached to.

I was wondering the same thing. Here is the manual

Pin 3 - TX and pin 4 - RX are the RS232 communications port. The RS232 to USB cable I use (as listed earlier) works between the battery and my computer with no issues.

The whole discussion with the V1 battery was the fact that the RS232 port did not work. ECO-Worthy waffled on the issue, finally acknowledged the problem and in my case sent me what I suppose is the V2 BMS. I installed it and the ports work as I expected. I just do not have a second V2 to verify if all batteries in the stack can be monitored using the ECO-Worthy provided software connected to the RS232 on the Master. An earlier post in this thread suggested that all batteries can be monitored via the Master BMS. This will only work using the ECO-Worthy supplied software or the JBDTools_ChangePow_20241226.exe version as these two versions include battery address in the commands sent by the software to the battery. SA just needs to make minor modifications to their software (If all can be monitored from the Master).

Hopefully it is on their list to do. I added the diagram to the resource
Most of the end users just want the simples way to talk to their battery. It would be nice to have a simple single device list for the RS485, RS232, and CAN in the resource. I'll also add the Quad Waveshare 4:1 RJ45 unit.

I watched that this morning. He did a good job. I noticed that he had both the V1 with the blue logo and no address sticker and the V2 with the sticker in the review. The interior views were of the V2 for sure because I saw the 4 balance connectors on the bms and the BT antenna wire.
