    Just now ordered them. Hope everything works out for this newbie who just dove in deep.
  • Post in thread: Cinergi's 28 kWh / 4 kW Solar / 10 kW inverter RV build

    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...
  • Post in thread: LiFePO4 Voltage Chart?

    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...
  • Post in thread: Bought 16 EVE LF280 Batteries

    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.
  • Post in thread: Micro Inverters

    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...
  • Post in thread: Anyone make their own cable lugs?

    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.

    Lots of good information here for me to digest. Thanks a lot. -- Steve

    Thanks. From where?

    Thanks.?
  • Post in thread: 280Ah 3.2V battery seller on Alibaba seller OK?

    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...
  • Post in thread: Bought 16 EVE LF280 Batteries

    See my response a couple minutes ago. My dispute is that I was misled.
  • Post in thread: Bought 16 EVE LF280 Batteries

    See my post from a few minutes ago. I don't think I would trust this company.
  • Post in thread: Heltec BMS' (up to 350A) with Active Balancing & Independent Active Balancers

    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...
  • Post in thread: Cheap 4kwh LiFePO4 batteries from Batteryclearancewarehouse

    I'm new so sorry for dumb question.. gas can is sitting next to one unit but two are in the picture, correct?
  • Post in thread: Cheap 4kwh LiFePO4 batteries from Batteryclearancewarehouse

    now you're just bragging right? :-)
  • Post in thread: Cheap 4kwh LiFePO4 batteries from Batteryclearancewarehouse

    The one I responded to. Anyway I think I can see there's two..
  • Post in thread: 280Ah 3.2V battery seller on Alibaba seller OK?

    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.
  • Post in thread: Heltec BMS' (up to 350A) with Active Balancing & Independent Active Balancers

    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.
  • Post in thread: 48v RV Build Plan

    I wish it was for 200 or 300 amps. my EVE 280ah X 16 setup needs a bigger bms (I think! ;-). Thanks for this thread. -- Steve
  • Post in thread: elongated bus bars

    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 -- Steve
  • Post in thread: Bought 16 EVE LF280 Batteries

    Sorry just saw this. I'm still waiting for a tracking number. I don't think that this wait is unusual though.
  • Post in thread: Price of solar panels

    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..
  • Post in thread: Cinergi's 28 kWh / 4 kW Solar / 10 kW inverter RV build

    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...
  • Post in thread: BMS ideas for 280AH 16s EVE cell system from Amy at Shenzhen Luyuan / Xuba

    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.
  • Post in thread: Bought 16 EVE LF280 Batteries

    This is great news! Thanks for letting me know about your like experience. I am also So Cal.
  • Post in thread: LiFePO4 Voltage Chart?

    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...

    Still waiting on tracking number..
  • Post in thread: Bought 16 EVE LF280 Batteries

    I have now we received all of my batteries. Next step I guess is the top them off?
  • Post in thread: REC 260PE Z-Link Used Panels - $75

    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.?
  • Post in thread: Bought 16 EVE LF280 Batteries

    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.
