Thanks for the reply. I appreciate it. I'm trying to put together my own 16 X EVE 280Ah, 48V system with only a digital design and software engineering background.
This BMS design from @BiduleOhm is definitely looking interesting, based on the problems I've seen with some of the less expensive...
Just read this whole thread. As a newbie I have to admit it is mostly confusing. Seems like, in this case, we've defeated the purpose of using a forum to gather accurate and meaningful data.
I wish there was a way to separate the wheat from the chaff as you say. Guess I'll have to just keep...
I ordered 16 of the EVE 280Ah LiFePO4 batteries on 7/11/20 from Shenzhen Basen Technology, China. Cost was $107/kWh delivered via boat/FedEx. Should arrive in 25-35 days according to seller.
I was told yesterday they've shipped.
Thanks for the thoughtful response. I too am re-evaluating how batteries can help me out besides making very sure certain fridge items are always available. That was the first thing. Then other important things when power is turned off because providers can't yet deal with fire near their...
They are very nice Lugs. I assume you're referring to your lugs when you talk about "lengthening the shaft"? When would you ever need to lengthen the shaft of a lug? Guess I don't understand. Thanks.
Just got an answer from another company that looks pretty good at first glance. Good price for the same batteries. It's name is "Shenzhen Basen Technology Co., Ltd". Ugh. Help, please. Anyone used either of these companies? 'Basen' seems pretty good to me so far.. I'll keep sniffing around I...
I have wondered if crimp-then-solder could be problematic. Since the wire and connector must be somewhat dissimilar metals, couldn't heating up the both of them to add solder decrease the contact area (from the crimp), and increase resistance? I don't really know of course and admit I am an...
Just bought 16 batteries from Shenzhen Basen Technology.
So I guess my questions here are moot. I've started another thread based on my purchase. Thanks for the space.
I believe this because crimping presses the conducting metals together with great force, while soldering may "bridge the gap" between the conductors if not crimped, and the solder itself can end up as the conductor, and is a relatively poor conductor.
Hi. I'm thinking aluminum for my bus bars too. can you give any info regarding how you decided size? I've heard 4x20mm, and and also 10x30mm.
Thanks

Well today is August 7th 2020. What would you (all) say is it good price per hundred Watts right now? I'm gonna also post a question about some used REC panels I found..
Do you have something between the batteries in your box? I've heard that if the batteries rub together long enough, that blue outer cover breaks down and the metal case is exposed and can short to its neighbor. I'm a newbie, so I'll defer to others, but this was told to me by a guy who runs a...
Pardon me but did you get all the information you needed for your BMS question? I'm waiting for the same number of the same kind of batteries to arrive but I'm also wondering about a BMS :-) . Thanks.
Thanks a lot for the response. Pretty sure I understand everything you said up to maybe the last sentence.
WRT that, I think I understand you to mean that you don't want to check SOC using current if there is already current moving into or out of the battery (ie, current with current...
Well I've got my 16 new 280 Ah lfp batteries. I guess I need to top them off but then I need to figure out what to do with an inverter and buy panels. Really feel like now, after waiting an extra month to get the batteries I need to get some panels and an inverter so I can make some electricity.?
Thanks. Sure don't want to have to do that. Especially since the plan was always to increase storage and maybe help friends/neighbors build their own systems.
