I've been trying to decide between 16 or 32 from Jenny Wu too. 32 more would probably be overkill, but I'd kinda rather have them than not.I'm working on an order of 32 CATL 302's from Jenny myself right now.
I opted for 32 to reduce the drawdown on one set and give me more headroom for electrical growth in the future.I've been trying to decide between 16 or 32 from Jenny Wu too. 32 more would probably be overkill, but I'd kinda rather have them than not.
I already have 16 I just put together, so the next 16 would be exactly along your thinking. If I got 32, it could be the same, but also I'm ordering from China, so it's a better cost basis for shipping. And since I've gotten started down this rabbit hole, I have family interested in it. So I figure somebody can use them or I can use them. I also tend to overdo things a bit when I find something good. This is also why I end up with huge bags of candy. ?I opted for 32 to reduce the drawdown on one set and give me more headroom for electrical growth in the future.
Also, I expect the minerals used in these batteries to become a lot more expensive in addition to inflation price pressure.
I was going to buy 16 Eve LF280K batteries, unless there's a better current recommendation for the money. I'll likely use the slow boat from China, assuming it's cheaper as I'm still waiting for an inverter. Who do you guys recommend contacting? Jenny, Amy, Amie etc...
Price is important, but obviously getting genuine new grade A cells and having a trustworthy source is most important... Coming with decent bus bars (preferably with small holes and a "kink" in them to release stress) is a plus.
Best practice for payment method is a good CC or use PP?
Last time I checked, the 304 AH cells were actually as cheap or cheaper than the 280 AH cells, but that can change.I was going to buy 16 Eve LF280K batteries, unless there's a better current recommendation for the money.

Thank you, I will contact him. Also, I have seen some recent images of the Eve 280's with a welded on "adaptor" which appears to have two taped holes, rather than the single. I haven't seen a pre-tapped busbar for it, but it does look like it might offer a superior connection. I'm curious to learn more about it.

I have used Ryan Zeng 2 times and received grade A cells both times direct from china on the slow boat ride. he can provide ship tracking and I had no problems. the last order I received in December 2021.
I emailed Ryan Zeng to get more complete contact information.

the above link is from Ryan Zeng
further, he states:
This is EVE LF280, which is a link containing the price of the U.S. warehouse and shipment from China.
1. Us warehouse: the goods are in transit. If everything goes well, it is expected to be available in two weeks. This will enable buyers in urgent need of batteries to provide faster transportation services.
2. Shipment from China, the current transportation time is about 2 months
At present, due to the coming of the new year, the continuous rise in the cost of raw materials and more factors, the price of batteries has also increased compared with before, and the inventory is very tight. According to previous years' experience, this situation may last until March to April next year. If any friends need it,can consult in advance and make a purchase plan.
and he also said to tell you this:
In addition, if you can, if your friends contact us through your sharing way, you can remind them to mention your name, so that we can better give the best discount and service.Thank you!
my name is Michael Clark >>>> in the forum I just used Michael D
seems like they have stock or have a shipment going to a USA warehouse for quicker delivery.

Ryan has always been very helpful and can communicate in good English. hope you have success in your LiFePO4 efforts. they also sell other things like BMS etc , I am using the Electrodacus SBMS0 on my 24-volt builds
cheers, Michael D ?
the last set of 32 EVE 280Ah LF280K cells I bought had the welded-on pre-tapped threaded holes. that way I am able to use other sizes of set screws/grub screws with the serrated flange nut method... some people like the welded on stud method.... nickel-plated copper busbars, ss washers, ss serrated flange nuts, and ss studs were included, I advise to get double the busbar order for initial top balancing and paralleling the cells. ( I received those on December 4th, 2021). so his response was December 2021 also
I have 96 cells (LiFePO4 272Ah and 28Ah)cycling that have all been purchased via the china direct method through Alibaba... this was the cheaper method but expect 60 plus days before it gets to you....
good luck with your DIY project...?
I believe most all resellers get their cells from the same factory, all cells I received had intact QR codes, no used scratched-off ones or any BS like that.
definitely use your credit card to pay....
I have never seen any with the two tapped holes like the link you provided... wonder what the bus bars look like???Thank you, I will contact him.

Do you have a link or contact info for how to do this? I didn't see a direct buy link on their site.If you buy cells from EVE directly
Yes, they have a store on alibaba https://evebatteryglobal.en.alibaba.com/Do you have a link or contact info for how to do this? I didn't see a direct buy link on their site.
