Well in the back of my mind I knew it was only a matter of time, and now in less than 3 years the basen 280 EVE "Grade A" is dead. Checked the voltage and its 0 volts (or 0.012 v). Purchased from Alex Chen in Feb 2021... This was in a 8s battery back with an overkill solar BMS, the other cells...

I just stumbled across this and based on what I am seeing, The EVE official store could very well just kill off Luyuan and other alibaba sellers: https://www.alibaba.com/product-detail/EVE-LF280K-Lifepo4-3-2V-310ah_1600140733108.html?spm=a2700.shop_plgr.41413.9.2af72e93P0RAnB vs...

So I don't know how but I guess Xuba and Basen must have sold my information as on a weekly basis I get emails from lifepo venders from alibaba telling me to buy cells. They tell me they are grade A and perfect, I never seem to get anyone telling me they are grade B...hrmm... The other day I...

I'm starting a new business with a partner selling refurbished servers, we got some dell 1950 servers, they are pretty old for modern use but could be something that you could tinker with if you wanted to learn linux or what not. We decided to just give these away: we have about 4 of these 2x...

First it was the BMS units catching fire/mosfets burning, then it was BMS having PIA methods of waking up, but now they are straight up going to destory your cells: JBD all the way, NO WAY JK.

If EVs really want to take off they better stop with these BS ranges: Stated range of 340; Actually Tested Range: 254 and you risk damaging your battery so actual real world more like 220 miles if you stop driving at around 20% left. 220 miles not towing. This is a cyber flop. Basically if...

https://batteryhookup.com/products/4-new-eve-3-2v-280ah-lk280k-lifepo4-prismatic Very good price for what looks to be legit V3 with test report and real qr codes. Only place right now that has stock in the USA BUT probably have to pay sales tax and shipping...

Pretty decent but only if you have deep pockets: https://www.sunfunkits.com/product/135/48-cell-pallet-ruipi-rept-280-ah-international-warehouse Minimum order is 96 cells. Grade A. Good alternative to EVE 280 in my opinion, currently am using 16 to build an EEL v3 kit.

They said they were $95.00 a cell but where?

plenty of 48v batteries are, but what about 12v 100ah small batteries, I can't say I have come across any battery that is 12v 100ah with a UL 1973 listing.

As much as this is going to annoy, I think the fourm needs to impement the probation rule where anyone new has to wait 15 or 30 days before they can post. I think this will stop the spammer bots. Also limit posting by user to max of 5/day until they are at least 6 months old. I ran a RC off...

Just saw this: https://www.gobelpower.com/gobel-power-gpsr1pc200b-512v-280ah-15kwh-10kw-lifepo4-server-rack-battery_p107.html?ref=ogga&cp=SAVING12OFG Wow, No heating, grade B cells, and cost more than the Eg4 power pro. I'm a bit disappointed in Andy on how he didn't address the alternatives...

The inverters that have grid connectivity, are they worth having? If you are never planning on selling back to the utility company but instead just have a transfer switch / sub panel to power your house? The price difference is substantial, so if you are not planning on connecting to the grid...

So I mentioned this in a reply a go and forgot, but I think you could do well with some ads that are not Google but rather self run. https://www.rcgroups.com/forums/index.php This is a site an example, i'm sure anyone fooling with drones will know it. The adds on this are actually not bad, its...

Very interesting videos, I'm using YouTube translate to make subtitles, but looks like this guy is buying cells and doing tests, finding out re-lasered qr codes and more. Is he a member of the forums?

Curious if anyone knows if these BMS units have internal shunts like the JBD.

I really hate doing this but I think once again my cheapness has caught up with me.... I'm having issues with my Sungoldpower 6500 (mpp lv6548 clone) having flicker lights issue and I suspect its because of dirty sinewave output. No replies to many emails, what is the best way to contact them do...

https://lithicoretech.com/contact-us/ https://ezealco.com/contact-us/ In Nov. 2021 I went to Lithicore / Docantech warehouse on Goar Road in Houston to see what they had going on, didn't buy anything because the cells were 2019 EVE280DK. So I called them on (346) 265-7995 "Thanks for calling...

Since When? When has Daly been able to upgrade its firmware? Well apparently for a while now! Seriously JBD you guys are slacking now, we demand upgradeable firmware!

So I'm just doing dumb little test with my sun gold, I"m noticing almost a 2.5 volt difference between what the inverter is saying and what the batteries are, granted I'm using 4 x 4s lfp rc car batteries to get to 48v, but still this is concerning. E.g. my batts are at 53.5v but the sun gold...

So I just got mine, well under 1k delivered and for all accounts looks awesome, but now I am seeing these F90 Fake firmware posts etc... As curiosity I reached out out to MPP solar and they immediately it said its a clone/rip off unit. So what is the deal here? How can we find out, is there...

I see a lot of people now doing full house solar/battery and it looks appealing, esp the part going full off grid... But the numbers.... tricky. My electric is about $0.12/KW and I'm in Orange, Tx, the utility averages about $168/Month on a 1200' house but but I can put up about 15 KW of solar...

Anyone seen something like this, an expandable collapsible tent/dome/igloo that instead of nylon has flexible solar panels? this is a concept I found looks like it never made it to market: https://odditymall.com/solar-tent-with-heated-floors

https://www.dailymail.co.uk/news/article-11458267/Criminals-stealing-solar-panels-thefts-soaring-amid-rocketing-energy-bills.html Considering from all he smash and grabs, catalytic converter thefts, porch pirates I'm surprised this hasn't caught on. Just wait for someone to go on vacation and...

So, anyone here about this company? Or is it another money grab on the battery hype train? https://lyten.com/lyten-launches-lithium-sulfur-battery-platform/

Are these basically all the same thing? They have this with coupon for under $1000 and free shipping for the mppt that has 250V, looks exactly like the MPP LV6548 Has the same TUV/UL confirmation.

Ok yes this is a pie in the sky type post, but assuming you had 150 cells or so LFP like 280s how would one go about making a home made DC fast charger for EVs It would not have to be like 150 KW, but something like 20-50 KW would be great also. I see people have made DC to AC and then Back to...

Does anyone have any plans available for some open source type BMS designs? Looking to make a 12 cell BMS which is not very common. I have fooled a bit with Arduinos before.

I'm thinking about making a 36v battery with some EVE 280 cells. I actually have a 16s battery but 2 cells are basically useless so I will be making a 36v setup with them. First I thought about making 3x 4s batteries and connecting them, but now I'm thinking it would be better just to have 1...

anyone selling these like Amazon? I'm talking about the rigid panels not the flexible ones.

Recently, I am thinking relying on AH is not enough to determine cell quality, so I finally ponied up the cash and bought a ZKE-40 tester and tested 1 of my Luyuan 280K cells, matched & batched genuine. As you can see it falls a bit short on the AH, but at the same time exceed the WH of the...

Can someone explain the difference, a friend of mine just got a trophy server rack and it has a SOC and a SOH setting, what is the difference between these settings?

I fail to understand this server rack form factor, its heavy and not cheap, you have to buy racks. Only thing I can say its looks cool, and I work at a data center so thumbs up for that, But even the cheapest one around is going to run almost $1800 by the time you add shipping. Vs 4x...

I have 32 Luyuan LF280K cells I will provide the alibaba receipt and the excel sheet Amy Wan sent me, All of these are between 284-285 AH according to the tests. They have never been used. They look to be made in December 2021. I was going to do a large conversion battery bank but I don't have...
