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...

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...

May I ask - how did you feed the external power source for the Chargery? Presently - using internal power on a BMS16T (only using 8 cells / 24V though)... and want to changeover to external as so many have recommended.

RE: Charger Shunt Errors - Calibrate or Not ? I've noticed that my Charger 300A shunt shows 1A for about 20 minutes after my batteries are disconnected - then reducing to 0A. Verified current 0A via Fluke clamp on ammeter against battery output + and and - Which brings me to 2 questions: 1...

Sounds like our Batteries were cousins... having likely shared the same ship.

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...

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...

Feel free to inquire with EVE directly as well. I did but have not received a reply yet. https://en.evebattery.com/contact/contact.html NOTING: Someone poked fun at my reference to an EVE auditor a few days back. Well here it is.

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...

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...

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...

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...

Amy says - I really don't understand how a person who made a point of noting the NEW 280N (Type 71) versus the OLD LK280 2020 (Type 66) -- and who now makes a point of emphasizing the LK280K (Type 76) --- suddenly doesn't seem to understand that Type 66 is NOT LK280N. All while my Alibaba...

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...

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?

Curious if anyone ever fully decoded the Manufacturing Date block for EVE stock?

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).

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...

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...

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...

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...

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...

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...

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...

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...

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...

Has anyone purchase a 3 Megawatt Tesla Megapack for their Disaster Compound, Solar Farm, or Disaster Recovery locations? https://www.tesla.com/megapack

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.

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...

5 out of 6 of my Miady cells are dead, melted open, or billow smoke on charging. Video of Miady Smoking..

Basen told me that US stock was out a few hours ago. They tried to press LCL of Lishen 272AH.

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.

My Miady 16AH just melted open ... current pull was in the low 30's -- well below the 42A max continuous current showing on Miady's spec's sheet.
