If you have multiple Mason packs, what cable do you use to connect the packs together?
custom made battery box for eve LF280K cells
- Thread starter sergea
- Start date
you can just use a standard ethernet cable to connect the packs, via the RS485 ports (edit: assuming you meant communications here)

busbars.
i dont daisy chain, too much current , so i have each battery connected to a common busbar ( like the eg4 racks), where the positive and negative connection to the inverters arebon opposite side
as for interconnecting the comms, just a plain utp cable
All four packs have been in service since June without issue! (*knock on wood*)
Also why do you want flexible busbars when the box ensures the cells can't move?
Remember I've got those cells with the damaged/bent terminals. Trust me there's absolutely no way I'd be using them otherwise.
oh right, right, my bad! yeah, good call!!

Yes, that is what I was talking about. The packs communicating together. Thanks.
The new seplos bms version 16 (with bluetooth and autoconfigure) can be included with the diy mason 280 kit.
I saw that they were about to release it and asked if the 4 kits I ordered could include the new version.
It was an additional 40$ for me.
Although i'm not sure whether it has additional cost if you order hasn't been handed over to the local shipping company (they had to request for the parcel to be shipped back, because they had just handed it over)

Can they work in parallel with the previous BMS version?

Solar Sponge.
Which protocol do those BMS use for inverters communication?

they support a number of protocols ( pylontech being one of them ), also both rs485 and CANbus over the same port...
the last bit a bit plus to the older versions, where you needed to order a specific rs485 or the canbus version
Took me a while to come back to you but I asked it to seplos sales and this was their response:
"
V15 and V16 are compatible
The difference between the V15 and V16 is that the V16 can communicate with CAN and 485, the V15 cannot.The V15 also has no way to connect to Bluetooth
"

I've built my own battery rack, which has four shelves for two rows of 8 cells on each, same layout as in the Seplos.
I'd like to duplicate the compression used in the Seplos, does anyone know the length of the cells from the front plate to the back plate once compressed please?
I understand the foam is 3mm thick, not sure what EVA foam is but I have some 3mm Plastazote® LD33 superior closed cell foam on order.
I was going to use spring compression, but realised this will protrude from the front of the rack.

Can you tell me about your experience with DDP shipping from China? I have 17 EVE 280 cells on order from Gobel Power, shipped DDP to Saskatchewan likely to arrive in late January. Did you need to us a border broker or did the product just show up at your door? When I read Incoterms for DDP, it sounds like the seller is responsible for everything, right up to delivery at my door.
It just showed up at my door. I didn't have to do anything.

Its Epoxy Glass Fibre Sheet GRP G10 also known as FR4
I'm in the UK and I got mine from eBay although it doesn't have adhesive (I didn't want adhesive) https://www.ebay.co.uk/itm/133036899692
You need to message the seller with dimensions and quantity, use Google translate as he replies in Spanish, I ordered 18 sheets at 206 x 175 x 1mm and with carriage it came to £36, it was delivered within a about a week.
You can also order them from Docan China, but shipping is expensive.
