TRY HERE.. https://www.amazon.com/dp/B08K8ZY8PZ?psc=1&ref=ppx_yo2ov_dt_b_product_details for the foam..

I got the boxes from eBay and waited and waited two for 55 total , i think then bought all the rest of the internals and copied the wiring for my needs..the components I could get but a complete box assembled was too much so I just borrowed their wiring methods and did it myself :)

Final update...Got it working my diagram was correct but I could not get the BMS to turn on by pressing the on switch.. (Zero volts on output terminal) What i found is you need the unit turned on and use a power supply to inject a charging current and that boots the BMS for the first time ...

I know that's why I go slow because there is a lot of energy involved here it can melt a wrench.... I am just frustrated with their idea of tech support three requests and the same document sent all three times.. Ahh well I think I have got it just paranoid loll!

That was my plan as I can see the orientation... I will post a picture when done but I am waiting on eva foam they forgot to send but after I get that i will populate and post a picture for the forum to see and give me a blessing :) Hopefully!

I ordered 16 of the ganfeng 280 @80$ total cost with shipping from china 1565.55 40-45 day delivery after one week processing will see how it turns out..

I wonder if a EG4 Chargeverter would help... You might want to ask EG4 about that...

hmm...

Don't USE the Ones I posted earlier they are in fact true bimetallic bonded lugs meant for connecting aluminum wires to copper... They are not to be used for copper to copper sorry!!...

Looking at breakers that go between the inverter and batteries they have 125 Amp 60VDC Breakers out now.. And I saw these type of lugs to connect to the breakers... They look like dissimilar metals but in their install video they show using it on copper cables. Just thought this might be an...

I have a kit from Seplos and they sent me the battery config its suppose to be 4s2p but if I load the batteries as in step six then place the bus-bars as in step seven I think I will have a big bang! And in step seven I see that the serial bar codes do not line up as the way the step six shows...

This is an older post but I have just installed power switches on my units and wanted to add a few pictures.. You need a latching power switch I used a Normally Open 16mm one.. I had a hydraulic knock out punch and used a 16mm knock out...A drill would work too. The plug on connector I used is a...

yes the bus-bars are exactly the same looks like the battery will eat itself with the first step install!

8 cells total four sets of two 3.2v cells (in parallel) those are then placed in series to give 12.8v See attached picture...

Also in the 7th step if you look at the serial identifier codes they are mismatched from that of step 6..doh.

rivet nuts would be a quick fix..

Did you try and hook up a small charging voltage to wake up the bms?

I will also upload a diagram of my thinking but need a little bit of time to set that up...

I have a Hydraulic crimp and that's what they use on the ones I mentioned just seems easier fit ... I think I will order some and give it a try..
