That seems about right. I did not calculate it as you did but I estimated arround 20-30% difference in SOC witch results in 55-82 amp hours. I was aware that i would not be able to put that much energy in the rest of the cells. I was still making up my mind if i should: 1) put them in...

Okay, thank you for the reference. I tried to find similar topics but did not look well enough I guess. I will read up on this tutorial - thank you again! Consider the topic closed. (At least for me)

I did not count but i would say at least 15h.

Hello, I have been researching the best way to top-balance my cells (4x 280A) and came to the conclusion that most of the people connect the cells in parallel and charge them up to 3.65V with a regulated PSU. Story why it would take me so long: I have tried it with my 5A (set at 4.5A) PSU...

True, to protect the branch it makes sense but in my case we are talking about a cable length from the bus-bar to the inverter from around 0.7m (27 inches). The cable is secured and protected from external force and in case of an issue my system must not be always on. I might still put a fuse...

The inverter has a 150A internal DC fuse, i would double fuse the inverter and if i would take a smaller one (100A) i would kill the inverter before it goes into overcurrent (and shutting itself off the way it is designed).

Thank you for all your suggestions and comments, I really appreciate it. I have done a more precise calculation for my loads. Nominal: max. 110A but most of the time below 50A Worst case for 0.5s: ~180A My conclusion and way to go will be: Buy the 200A BMS...

Thanks for the detailed answer. Regarding the wiring I will keep the cables as short as possible and oversize the cables regarding max. current for sure. This is exactly the point what I am worrying about, making sure that I do not have to replace the my fuse just because i accidentally...

Hey folks, For the past few days i can't wrap my head around on how to select the correct BMS size because of the inverter. The right fuse size is also a huge question for me. Explanation: In my camper van setup (12V) I will be using an Victron Multiplus 12/800 inverter. This means the...

Thank you for you reply and time! :) This sums up all my thoughts and doubts. I have already made experience with both "ways". Especially after the periode after July 2020 when the Vat. free threshold changed, some of my aliexpress packages were not declared correctly and i have had to pay...

Thanks for the update. I just ordered mine via Docan (Amy Zheng). I also went for the LF280K from EVE. They come from China with DDP shipping. So time to wait but I am confident all will be perfect since she is one of the most trusted suppliers here. I also tried to find a Daria Long at Basen...

$148 per cell including shipping from an eu warehouse?

Hey, First of all thanks for the quick answer - greatly appreciated. So Daria Long sent you a quote from a european warehouse aswell from a chinese one? How did you purchase them? Directly via paypal or via alibaba? Did you test them already? Are they as promised? Thanks again :)

Good evening, I was wondering if anybody has already made a purchase of cells (preferably from the two well known and respected sellers in this forum Jenny Wu or Amy Zheng) and shipped them to Europe? Sadly the import fees increased dramatically mid 2021 and that is why I was wondering if...
