Refund refused! After two months of struggling, sending back fraudulent labeled batteries where they have a sticker of 200ah instead of the real power 10-14 ah ( weight only 2,7 kg instead of 40-50kg) .Sending proof you can also find everywhere on the internet, Wikipedia they did not accept my complaint that this was fraudulent sale and decided within a few minutes after sending the proof ...so without further looking into the case that they would not refund , this they named solution one: NO REFUND..... I DID NOT FIND ANOTHER SOLUTION! If you want to loose money this is the site you have to buy ! Absolutely no customer protection! They seller has all the power and AliExpress supports fraudulent sales that's clear . I am very disappointed and cannot do anything else then tell you people who are reading be aware do not buy at this company , there are others perhaps more expensive but with a good reputation and honest which cannot be said about AliExpress.
