Steve - Firstly, allow me to thank you for your great contributions to this board. I greatly appreciate your knowledge and willingness to share. It's tremendously valuable - and no doubt of great benefit to many on this board.
With that said, No member should be made to feel...
RE: Luyuan Concerns - Are these Serial Numbers consistent with Grade A Factory Matching (attached)
I truly hope I am wrong here - but I've purchased 8x Eve 280N from Amy/Luyuan and 8x EVE 105AH cells as well. I paid a surcharge for the premise of GRADE A full factory matching - and relied...
Dear Mr. Bob - Would it be possible for you to allow us to focus on the core matter of this thread?
You have 27 posts that reference Amy/Luyuan - and many are positive. Yet - you stated a few days ago - you've never ordered from her.
Yet you jumped in many many times into a closed thread...
RE: Giandel advised - Ground/Neutral Bonding not supported - floating only - 24V / 3000W PSU
Hi All,
Giandel recently advised me they do NOT support bonding of Ground to Neutral with their 24V/3000W/PSU inverter.
The Tesla charger wouldn't function along with other devices that did soft 5mA...
Excited to receive my EVE cells today.
For those wondering about Cells via the LA and Long Beach ports --- it was a while. 3 months and 11 days - payment to door.
Payment 7-3-2021
To Logistics Agent PRC 7-18-2021 +15 days
Ship leaves Yantian PRC 8-29-2021...
Appreciate the line of thought. I have reached out to Miady. They've suggested a refund of at least one cell - but keep insisting that their specifications are tested at their factory.
Hi Amy - 5.6AH / 280AH = +/- %2.00 Probably a good idea to add this to the product specification pre-sales.
2 Questions:
1) Any idea how that compares to cell capacity ranges used by other Commercial ESS systems (Tesla Powerwall, EVE Mega, etc.) 2% vs. 1% vs ?
2) Did EVE reply to...
Saw this screenshot from another DIY post... According to this my "Factory Matched Grade A" set of 8 includes
2 cells that are Type 66.. manufactured on 2 separate dates (ACH and ACG) . Then 6 cells on Type 71 Manufactured on B3D and B3E.
The 105 x 8 are then all Type 65 B5S and...
Thank you for the warm welcome! I've been struggling with what brand & supplier to use for 250+ AH LifePO4 prismatics - and I see this forum brings with it a wealth of experiences in this regard.
Ironic my first post was of this temporary measure - Miady 16AH from Amazon.
Hi Amy - Thank you for this very thorough response. The detail level is quite helpful.
It also sounds like an opportunity for EVE to update their PDF specifications to avoid buyer confusion. From the description, it sounds as though QR serialization date may be separate from...
Indeed! I lived 9 years in asia - and have worked with chinese manufacturers before.
I can always have agents in HK/CN/SG, etc. reach out for the quotes too and smell the difference.
In a single energy trade show - with business cards printed in the parking lot - I would have been able...
Guessing within 2 weeks. I'll take photos of QR's (assuming that's your next question).
I've also inquired with Auditor at EVE to trace the serial numbers in question and advice of Specification # and Manufacturing Date.
Perhaps, I should have paid more for EVE Direct sample order to EVE to...
I asked Jason about the DCC-300 v1.1 instructions (DCC on POS) vs. the v1.0 DCC (and BMS8/16T) instructions which all show DCC on NEG.
He said that some customers have "suggested" that DCC on POS is safer.
At the risk of finding myself quick schooled by the EE community and Mike Holt...
Feel free to inquire with EVE directly as well. I did but have not received a reply yet.

NOTING: Someone poked fun at my reference to an EVE auditor a few days back. Well here it is.
I spoke to EVE's sales about full container loads of EVE LF280N for a friend.
20GP container = 1,728 pieces
40GP container = 4,320 pieces
I suggested $60/unit. They pitched > USD125 unit for FCL. Pre-pay first and then manufacture to spec and ship. No aging.
I half-joked - are you...
8.00 A 8 / 20 AH-rate = 0.4C charge rate.
I scoured Amazon reviews. Found another reference to Smoke. Many references to cells dead after a few charges. Another person who had a Melted abs top. Will noted the horrific chemical smells when he opened one. Others on Amazon have...
Has anyone purchase a 3 Megawatt Tesla Megapack for their Disaster Compound, Solar Farm, or Disaster Recovery locations?

RE: Borderline Capacity Finding - Interim - 272AH (0.5C) and 276 AH (0.3C)
Leaning toward "Accepting" this as "Close Enough" - even though part of me think 1C 280AH factory spec should be met.
HARDWARE: EVE 280 AH - x8 as 24V system.
-Stated as A - and factory matched/binned set...
BMS Selection - Chargery vs. Daly - 300A (for 280AH cells)
I continue to delay my order of Eve 280AH until I can pick the right BMS.
I had thought Chargery was interesting - but the complaints seem tremendous. Daly seemed a cheap alternative - but I see too many complaints there too.
Can...
Would you be able to share the serial numbers and the rough date received for each shipment?
Really curious about how many different 3-digit Manufacturing Date codes were in a "Factory Matched Grade A set" ? and how far apart the dates are (days vs weeks vs. months).
Thank you. Details are much appreciated Amy. I'm awaiting a reply from EVE still.
RE: TYPING: The comments above would require that (EVE) Specification PDF is incorrect re: 66 vs 71 (published by EVE 12/22/2019 saying N is 71). Are saying that ? or is EVE saying - old 280 and 280N...
Amy from Luyuan told me about the LF280K about 60 days ago:
"Wan Amy:
LF280K,6000 cycles, it is only needed in special fields, what we sell is LF280N"
Attaching JPG of chat session.....
Does this add up?
Thanks All.. closing the loop here.
I went with Chargery BMS16T 600A version (in case go 2p8s or 1p16s in future) -- and a single DCC 300A for common port setup now (will upgrade to 600A later if go 2p8s). I just purchased via Jason's website directly (Paypal/DHL express). Just...
Appreciate the words of wisdom.
In perusing the manual for the Chargery 16T and 8T versions - a few questions come to mind which I wonder if you might your thoughts on:
- Did you elect to leverage External Power or Power Pack Panel for the DCC? Saw a youtube reference to Cell 1...
Love that last line. They'd suggested that if I bond Neutral and Ground at inverter - that it would risk shock on the chassis. In light of this - interesting that the manual would include reference to support fixed sites in addition to vehicle/maritime. Presuming they didn't want to...
