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

[BarracudaBob]

another reason Im sticking with the EW rack battery. they are actively involved.

unfortunately my v2 I cannot get the screws off to move the wifi antenna. not sure why they are so tight.

oh well, moving on

Maybe we can find out what the screw is you can drill the head pop the cover off and take vice grips to take out the stud. I had to do that on my EG4 LP4V1. I drilled the screw head off and then replaced it after I pulled the cover off.

That must be their anti-tamper device...

Lot of weight being thrown around and shifted all it has to do is pull up and then screw a little bit to mess up the thread and it's stuck. Besides I love spare parts

Try tapping it with a hammer while turning it counterclockwise. If you have a soldering iron, warm up the screw—it will take a minute since it's attached to a large heatsink.

They moved them so the end user can get to the screws on the other side of the handle. Makes it EZ to take off the ears and handles for shipping so they don't get damaged by the FedUP guys

I guess that will be the end of the "Bent Ear Club"

I'm just wondering if this modification will now create the "crushed corner" club

Bent ear club taken so Handle Bar Club ??

If the other battery manufactures do not drop their prices soon I am going with EW.

If I change the protocol for the rs485-1 port to "Pace", will the EW software (ES-UP-V1.22.16) still connect to that port if I want to change it back to "PYLON"? In other words. is that software multilingual and auto detect? Anyone brave enough to try that? This is V1 battery that was my master to the inverter. I am now using my JK bms to connect to the inverter because the SOC reported is more in line with the voltage of the battery than the JBD bms, which has been saying 13% at 51.2v.

Ok, did some testing today. The JBD software commands are always present so no matter what protocol you set it for the software can talk to it. Solar Assistant also talked to it in JBD mode regardless what you set the RS485 to.

On my very first V1 battery I added the BMS to Daughterboard interconnection and it made the RS232 work with software. I just figured that it is the same commands as the JBD RS485 using a RS232 adapter into the RS232 jack on the V1 Battery..

I was able to connect the EW/JBD software to the RS232 on my V1 and read it. It was many months ago but I believe I used a similar wire as this. I may have had to flip the connections. I don't use this connection but nice to know it is there and works for those who want to add it.

Hi Bob
Please pardon this interruption. The thread regarding the EW server rack batteries is 104 pages now and finding specific differences between V1 and V2 is overwhelming.

I am posting this question for others to add in on it. Keeping it honest.

V1 BMS is JBD UP16S015
You can add Bluetooth for $10 or Bluetooth and WIFI both for $35

Missing Serial Cable between the BMS and the Front daughterboard to support the RS232. It was originally thought that the RS232 wouldn't operate on the V1 even with the cord. I just proved it will. I don't need the RS232 but it is there so climb that mountain!

I don't want WIFI so adding the $10 Bluetooth works for me. The $10 Bluetooth module has better range than the one below but there are fixes to that too.

V2 BMS is JBD UP15S019
Includes WIFI and Bluetooth on the BMS, has antenna that comes off it. Great for those who want it and a great feature that others don't have. WIFI is the future.

Has different balance cables so if you swap a V1 to a V2 BMS (old battery to new) you have to rewire it.

V2.1 to be shipped soon Bill Young just announced the differences. Antenna and handles placement changes. This help in WIFI/Bluetooth range and shipping damage to handles.

The V2 RS232 port will also respond to the PACE protocol which may solve any issues with Solar Assistant.

Thanks. I think I was having a brain fart about changing the rs485 comms to pace. I was thinking about comms to SA when I was looking at that. I now realize that setting must be for inverter comms.

Generally the selectable protocols for a BMS are only for the BMS to Inverter communications so you can find a common one between the Inverter and BMS. Many folks also believe it changes the Battery To Battery and PC host protocols, It does not.

The PACE Software I use for my SunGoldPower batteries (and two CyccleVolts) is SOKTools and it will display all the EW battery data when connected to the RS232 port. The issue however is battery/device addresses. Most of the JBD software uses the JBD Modbus-Ascii format and they do not use the extended format that allows the battery address in the command and this is one of the issues with SA. The JBD Modbus-RTU format requires the battery address in the command and only (as far as as I can tell) the EW software uses this format. If SA used this format then it would work.

It is my understanding that E-W is working with JBD and S-A to get everybody on the same page.

Yes, all true. I don't know where my random idea came from.

Well, that would be great. The next thing would be to allow selecting a second manufacturer (like JK, on another com port) within SA, to read those batteries as well. A "translator" on a second pi device would be cool too. Or I could just change out my 4 JK BMSs if they ever fix the JBD problem.

I have the same issue with EG4

Change after the BMS with the same simple one that's in the Vatrer

The key is really to get the JBD problem fixed. Then I could just reconfigure SA to look at either brand, one at a time at least. What I would really like is to see all the batteries in SA and have SA send the total bank info to the inverter for closed loop. That would get around the 15 rack battery limit as well.

Replacing 21 BMSs is not on my bucket list!

That's why I'm running two solar assistants, seem like the easiest solution

One smart shop would do it too if you could get it to talk to the inverter there's definitely room for someone to invent something

You are like a small power plant

FYI, Deep Dive into Super Smart BMS with Coulomb Counters. This is more of a personal experiment that I am setting up but very interesting. Some of the dumber BMS that operate only on voltage seem to outperform Smart BMS. In the long run the Smart BMS may save the cells by being more conservative.

I'll do a controlled discharge into a resistor (immersion heater) in the future.

I posted it here:

Post in thread 'Battery Capacity Tester'

Feb 20, 2025

Warning Deep Dive:

So I did a test to verify how the "Coulomb Counter" on the smart BMS stop charging & discharging. I'll do another test in the future on the discharge side. With the weather not getting everything to 100% in a while I turned off my loads and allowed the PV to take everything up to 100%. I have EG4 LifePower4 V1 and the Eco-Worthy V1 & V2 Rack Batteries. The BMS 100% Reset voltage on the LP4V1 is 56.6V and the E-W is 56.8V. I set the AIO to stop at 56.6V for bulk and float so not to Pack OV the EG4. I changed the E-W to match the EG4 to 56.6V. So when all the packs...

I’ve top balanced the 4 EW rack batteries (2 V1s + 2 V2s) by attaching a flying capacitor active balancer and achieved a pack voltage of 58v for several hours without the COV kicking in. Yes it was time consuming and tedious.

Question for EW users: Can I expect the JBD BMS passive balancer to keep a reasonable top balance over the long haul? OR, should I be seriously thinking about adding a permanent active balancer inside?

The balancer I’m currently using has a very low background current draw - something like 10mA, certainly nothing to be concerned about regarding parasitic drain.

If you get it balanced in the beginning do a couple deep discharges and full charge it'll be good moving forward. I'm using one since October was zero balancing issues I did set it for idle, 3.420V, and a differential of 10 millivolts it's been flawless ever since

Anyone come across any new discount codes? missed the boat on the amazon one that Will had (20solarWILL) ... well missed for additional 6pack(just bought 2piece).

This is a guess based on previous occurrences: Wait a couple of weeks - EW is getting new shipments in early March, and I would expect that then some new eBay codes might appear.

 

[whoinow]

I got all 7 of my EW batteries this week and mounted in the rack. I am going to get all the data lines setup and see how far out of whack things are. Most of them are around 35% SoC.
