Dear forum I ordered 34 EVE LF280K from Shenzhen Xuba Electronic Trading Co., Ltd. (SZXUBA) and would like to report about my bad experience. 1. GLS routed one box with 4 cells incorrectly and delivered it to somewhere else. This is not SZXUBA's fault, but they do more or less exactly nothing...

Capacity testing with validated tester is ongoing, it looks like all cells have lost some Ah during the ~14 months they're on earth.

What really disappoints me is Alibaba's behavior - Trade Assurance is nothing but a joke and the dispute seems to come to an end without any help... Me: They: Me: They: Guys, keep your hands off the China scammers!

That's exactly the case. To be honest I was wondering during negotiations how they can deliver cells without B mark produced after June 2022. Actually I expected to get cells with faked QR codes. That's the point where I should have canelled the negotiations but it was the only dealer who...

I paid 4395$ for the 34 cells (incl. the terminals, screws, bus bars and the undelivered isolation sheets) + trade assurance/payment fee. I.e. ~130 per cell. I requested a refund of 20% for the deviation between the agreed and actual production date and lowered my offer to 15%. Do you think...

Yes, of course: QR code in detail: And yes, of course I scanned the cells with a QR code scanner. They're all from Dec 2021. At least it looks like it's genuine EVE LF280K cells.

Short update: >3 months later I got 4 replacement cells for the ones that disappeard. Now they deliver cells with faked QR codes, examples: They claim it's original from EVE factory... Further: Capacity of 2 of the 4 cells is way lower than 280Ah. It really sucks with Xuba... Hands off...

I'm also interested which software you @perryfranz used. E-Tester software available on Mediafire looks different.

Hello DIYers I'm thinking about putting a DC MCCB as a disconnector (and load/short circuit protection for the MultiPluses) between my LiFePO4 battery bank and (a set of 3) Victron MultiPlus-II. I'm not that confident with DC as I'm with AC, therefore the following question might be stupid...
