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

I would request all to ship from the new batch just to have them all the same, but there is no guarantee that they would not get mixed anyhow. That happened to me on the 12v EW I ordered in groups of 4. One group had different bms's inside, 3 of them were new style with on board bluetooth and one was old style with plug in bluetooth.

That is a weird marketing approach. They have some available now, but not enough to fill all the anticipated orders before the next container gets here. If they run out, the listings for just one will have to wait too.

The rack was never offered for sale by itself.
By mixed, I mean you could end up with V2 from two different production batches, NOT V1 and V2 batteries.
 
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.

I tried it on the EG4 3K inverter a while back. The battery talked to the inverter and software with no changes to the windows software.

The software could still talk to it no matter what protocoled you try if it has JBD command/response action. That way it would talk to the battery nonmatter what protocol you select.

Give it a try
 
Thanks for the detailed input! Really appreciate the perspective on open loop vs closed loop. I've heard similar things about EG4's SOC drift issues, so your point about stability makes a lot of sense.

A few follow-ups:

Voltage thresholds: What voltage ranges do you recommend for open loop operation with mixed lithium batteries? I'm running a 48V system, and the ECO-WORTHY units have a slightly different discharge curve compared to EG4.

SmartShunt setup: Do you have any tips for integrating a SmartShunt with mixed battery brands?

Again, thanks for sharing your experience - definitely saving me from some potential headaches!
Hey folks,
Solar newbie here working on my first off-grid cabin setup. Currently running 3x EG4 LL-S v2 batteries (the ones with that slick-looking LCD screen), and need to expand capacity. Got my hands on a few ECO-WORTHY 48V rack batteries through a local supplier deal.

The kicker: Both units have what looks like identical communication ports - either RJ45 or RS485 depending on how you configure them. Manuals are vague AF about cross-brand compatibility though.

Tried:
1.Basic parallel connection (worked for power delivery)
2.Plugged in comms cables between EG4 master and ECO-WORTHY slave
3.Checked both brands' protocol documentation (EG4's MODBUS vs ECO's "custom closed protocol" whatever that means)

Got the EG4 inverter throwing "COMM ERROR 09" when attempting closed-loop communication. Weirdly, the ECO-WORTHY battery's LED status does change when connected, but no meaningful data transmission.

Real talk:
• Anyone successfully hacked together cross-brand comms between these?
• Are we dealing with different protocols disguised behind same physical ports?
• Would a Raspberry Pi protocol translator be worth the headache vs just buying more EG4s?

Not married to either brand - just trying to avoid vendor lock-in. The ECO units were 30% cheaper locally but I'll cut my losses if this turns into an engineering PhD project.

Appreciate any war stories from those who've mixed lithium brands!

My two cents. Don't worry about closed loop comms. Especially when you have a significant battery capacity. To me it offers very little but also potential risks like unexpected shutdown because battery bms soc has drifted from reality. The eg4s are known to not detect small amp draws. More batteries you add and the lower your draw per battery the worse it will get. Open loop operation based on voltage with a $100 smartshunt is the value and accuracy choice imo. Even small loads are detected. Nothing to get in the way of system stability. Even eg4 support recommend open loop when their battery comms is having issues due to firmware etc.

I use the CAN port with pylon to talk to the inverter and I'm not wanting to change that one. I was wanting to see if I could get solar assistant to connect to the the rack battery using pace protocol on the 485 port where I connect the laptop. At the last second I thought "what if this software wont connect to change it back?"

I believe the software will still talk to the battery but it has been a while. I tried a couple different protocol and they worked. Software was always able to connect to the battery. Worst case you may have to turn on/off the BMS.

Once I put them into production I don't mess with them that much. Get all your balancing and cycling done in the beginning and then put them to work.

Give it a try! I'll see if I can do some playing around tomorrow.

Yes understand that because I have ordered from Eco-Worthy before and gotten mixed products even from the same batch. I asked them to ship them all together and said I was happy to wait for the next container in late March so they would all be the same version but they were not willing to do that because eBay requires them to ship something.

Truly hoping I don't get two V2's with different BMS or something.

Hi everyone,

I'm thrilled to provide a comprehensive update on the recent battery upgrades we've implemented.

As you may recall, on February 13th, I shared four key upgrade measures, all of which have now been successfully rolled out. Building on these improvements, our engineering team has introduced two additional enhancements to further optimize your user experience.

Handle Relocation​

Firstly, we've redesigned the handle placement. It has been moved from the front panel to the mounting ear. Please note that the mounting ear will now be packaged separately with the product for user installation, rather than being pre-installed. This change significantly reduces the risk of the mounting ear bending during transit, with an expected improvement rate of 99.99%. We apologize to any "bent ear club" members who may be disappointed by this news, but we're confident you'll appreciate the enhanced durability.

With this relocation, the mounting ear's hole spacing has also been adjusted from 6cm to 11cm. Please refer to the attached diagram for detailed visuals.
1739950583860.png
This adjustment means that batteries launching in March will not be compatible with the previous 4-layer rack. To address this, we'll be releasing a new 4-layer rack and an all-new 6-layer rack by the end of March, ensuring compatibility with all battery versions.

Signal Antenna Enhancement​

Secondly, we've tackled the signal antenna issue. Our engineers identified that the weakened signal was due to the antenna being positioned inside the shielding metal casing. To rectify this, we've implemented a new mounting strategy: the antenna will now be attached to the metal component securing the air switch, with a 2mm thick foam double-sided adhesive for added stability. Additionally, a 10x20mm hole will be added to this metal component to further boost signal transmission. We anticipate this will extend the signal range to over 48 feet (approximately 15 meters) in unobstructed environments. We'd like to acknowledge @BarracudaBob from the forum, whose insightful suggestion closely aligned with our engineers' solution.

Version Identification​

For those who've inquired about distinguishing between V1 and V2 versions, here's a simple tip: V2 versions are equipped with Bluetooth & WiFi functionality, indicated by a MAC address printed on the front or side, and a Bluetooth logo in the top right corner of the label. Please note that the color of the positive and negative terminals, as well as the silk-screen printing color, are not reliable indicators for version identification.

Upcoming Battery Release​

The upcoming battery model will feature a BMS system identical to the V2 version. Therefore, we're considering it the V2.1 version, reflecting its subtle yet significant technological advancements.

Thank you for your continued support. We believe these upgrades will provide you with an even more satisfying user experience.

Yes, they have to ship something to get payment released. So you will get 1 of V2 and 3 of V2.1? I would not worry about it too much.
 
So, if you received a rack prior to the current sale, it will not be “rack ear spacing” compatible with the “V2.1” batteries?

The ears are interchangeable (and handle moving forward) so maybe they will offer the new ears and handles or just the ears with the new spacing for older units. Or vise-a-versa.
You can remove the old handles and put a small plastic plug cover over the holes.

There are always drilling it too...

Just looked at the pic again and wonder if the handle holes for mounting on the ear is at 6cm so they could be removed and new battery mounted on the older racks?

Just a thought.

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 :devilish:

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

Unless you're the 00.01% that does not make it without damage.
I guess that damage if to the face would be the terminals, which would probably break too.

The damage is usually the ears on the side or if FedUp drops it on the face and the handles push in. Otherwise their new improved high density foam distributes the force over the entire faceplate and it doesn't bend.

The handles being mounted on the "ears" thus closer to the bus bars of a rack may interfere with ease of attachment of the power cable to the rack bus bar. Many battery manufacturers use handles that fold over and lay flat.

At least now will be easier to remove...

Not sure what use they are once done moving around before mounting in a rack anyways.
You cannot get much use of them to load into the rack.
I don't think anyone strong enough to hold them and flip it horizontal to slide in.
Would need to support from the bottom anyway.
I personally would need a buddy or adjustable table.
 
The folding are nice but I don't know if they make a 3U version they're always on the larger batteries

I believe they do yes. I have other rack batteries with roughly the same dimensions that have the folding handles I think. 🤔
I could get some measurements today if anyone is interested.

I never reviewed the batteries, the company essentially collapsed before I was able to.
 
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
