  • Chinese suppliers of LifePO4 recommendations?

    Hi Guys
    I have decided I need to buy a few pallets of LifePO4 batteries for a few projects, decided against AGM.
    Can you recommend any chinese suppliers?
    Most companies I find recommended online are based in the USA where as we are in New Zealand so I would rather order direct from china if you have any favorite suppliers?

    Probably looking at 3.6v / 12v or 24v 100ah size units - we have a few projects where I need to get 24v 2000ah array or 48v 1000ah - so when I mean a pallet i mean an order size that you would use to power a house.

    At the moment I am looking at Aliexpress and have found a few options but am not feeling so sure about them - especially when listing title says 200ah and the specifications table says 100ah - obviously i dont want the english barrier to cause us to overspend.
    Anyhow your recommendations are appreciated.

    I would say Alibaba but it sounds like Aliexpress is the same thing.

      You will be sorry. I just did a work up for someone contemplating a 48 volt 415 Amp AGM vs an equivalent 16S2P 360 AH LFP
      • 48 volt 428 AH Rolls S-550 cost $2700 and carries a full 7 year warranty, made in the USA with many dealers to honor warranty and Rolls has been around for 60 years and not going out of biz.
      • 48 volt 415 AH Rolls S6 460 AGM cost $4400, and carries a full 7 year warranty, made in the USA with many dealers to honor warranty and Rolls has been around for 60 years and not going out of biz.
      • 48 volt 360 AH CALB LFP CA 180 16S2P cost $7,700 and carries a 1 year warranty made in China which makes it almost impossible to make a warranty claim. You also need to add about another $1000 in equipment and work around LFP weaknesses and charging parameters.
      If you insist on Chi-Com POS LFP batteries the best of the bunch is CALB. They can be purchased by Custom EV shops like

      EVTV

      If you buy from Alibaba (Chi-Com Ebay) you have absolutely no chance at a warranty claim that is only 1 year. But from a local quality manufacture you might get lucky with a warranty claim. Buy a quality AGM and no problems with warranty claims for 7 years. You get what you pay for.
