deleted, sorry
Have 4 boxes currently in service. They work as advertised. Charging to 90% and discharging to 10%. Only issue is the battery bms kept changing the desired charge values on the solarak inverter. I reset the charge, float, and equalization values via the solark, and it was changed the next day. Did this several times. Finally set things up correctly in the BMS, and the values on the solark stay set.Why haven't we had people bost their already set up systems with the boxes? I thought many already received their boxes. Let's have usage reviews.

noDoes the BMS have Bluetooth?
they use this bms in all their rack battery products ( different ah and coms versions of course)No. I believe this is the BMS they use in their EVE 280ah Mason kits.

get BMS in one week by DHL.If you have any luck let me know. I tried to reach out to Futronics but my email got returned. Seplos doesn't seem to want folks to make their own cable and instead buy theirs which is quite annoying. As I mentioned above I replaced my connectors with Amphenol but it was expensive.
No it is not 6.0 it is 8.0 connector are different for DIY280 case and other smaller case.Can anyone confirm or refute this? Was literally just about to buy one.
The state of charge is not exact. It took several days of complete charge/discharge for the bms to learn the capacity. It is getting more accurate every day. I have all 4 boxes in parallel. The inverter will report a charge value and the 4 boxes will all have different values, that average close to the value reported by the inverter. IE - inverter says 50% - box 1 says 55%, box 2 says 51%, box 3 says 47% and box 4 says 42%. It does always count down from the top box to the bottom. The actual voltage of each box seems to hover very close to the same value despite what is reports as the charge percentage. So in the case above the value of the voltage on all 4 boxes will be close to within a hundredth - 52.38 or 52.39.That's disappointing. Changing parameters via an app is much more convenient. How accurate is the reported SoC?
I'm just hoping it's better than the Sol-ark's internal SoC algorithmThe state of charge is not exact. It took several days of complete charge/discharge for the bms to learn the capacity.

I would like to switch to a busbar situation, and the values would probably be more accurate vs having the boxes daisy chained.
I think I was one of the first people to get and set up my boxes. I bought four (Henry @ Seplos was my sales guy, really helpful fellow).Why haven't we had people bost their already set up systems with the boxes? I thought many already received their boxes. Let's have usage reviews.
Here you go.Anybody know which fuse is used in the box?
Any way you could update the OP with relevant links?Hello everyone,
I have a company that is working on designing a custom 16s eve LP280K cell box that includes their own BMS 200A. I spent the money to have them do it. And hopefully some of you will be interested (and possibly share the initial cost ;-)) anyway, here is the initial design. The BMS screen will also be added.
it will be professional design, with flexible bus bar, fuse, bms, cell holder / insulation.
Just bring you your cells and you're done.
Any feed back ?

That is what this entire thread is about. The seplos battery kits were designed in response to sergea's request. My understanding is he footed the cost of the engineering for these kits. That we have them at all is a reflection of his willingness to share his idea with a company and pay for their development.Any way you could update the OP with relevant links?
I understand that, however it's nice to have links in the OP for whatever has been discussed so people don't have to scour through every single message in the thread to find relevant links. There are 23 pages in this thread. Not everyone has the time to read through all 23 pages to find important information.That is what this entire thread is about.
