My Build

Which black wires are you referring to? In the top pic, you have to bolt a wire to the board and connect to the battery Neg, on both sides of the board. Even tho there isn't a wire that came with the board, you fashion that wire up with a ring connector and bolt it. Or you could solder it directly to the board.

Ok maybe better to mount it this way. I flipped it over and the connection points are more accessible. I will disregard all the extra black leads in the instructioins and connect the White leads to eacj positive string. They caution to go in the order meaning B14+ should be last.
I Think I understand how to proceed and hopefully my next update will be a positive one.

I will assume I can make my balance connections to the Busbar and not the actual cell?

Ok I am down to 1 last connection. Can someone help me understandwhere C- is suppose to connect to

Success!!!! I didnt Blow it Up. Yes I know it is way out of Balance. Hopefully this thing will solve that.

Looking good I am still testing cells.

Looking good.... [emoji106]
I wonder if this bms could be tuned in for more current like 150A or more with changing big mosfets and add some heatsink's

What was the balance current again??

Here is a shot of the 4 main screens. There is a page with Balance Controls but I am hesitant to poke around too much not knowing what I am changing. Hope this helps.

Nice. Glad you got it figured out. So did the C- and B- end up hooking up to the same spot on the pack?
 
It is getting to be a real type C setup ( 48V Packs in Parallel ).
Follow with great intrest... i was going to do the same thing before idecide to go with the parallel packs.

Is it possible with those bms bords to connect severaltogetherand do theycommunicate with each other?

i see you have plenty of room in that server rack.. wanna see at least 15 packs in there;)

Yes I soldered then to the outgoing Negative busbar

Unfortunately Wim I had to abanndon the 48v pack for the Power rack. The cost to setup a proper BMS was too much not to mention the complexity. The 3 pack on the shelf are 1s100p. The 48v pack that was already made I will keep as a bench pack for testing.

I havet seen any information in the manual that would allow stacking these units. I'm not the best to try and experiment. Waiting for Daroamer to get one and do some testing.

I could possibly fit 5 packs per shelf but that might be pushing it. My goal was 10kw. 14 packs should get me there.

And this is what it looks like this morning. I did help it a little by hooking a small light bulb to the cells that were way off but doing quite well today. Now I would like to see it keep things in balance through the charche cycles.

I am very glad to see that is successful.... [emoji106]
Question does your bms constantly balance.....probably?
is it possible to set with program....?

Yes It does appear to be constantly working to bring in balance. There is a Start and Stop option on the main screen. Many of the parameters are adjustable. I will say I would not consider this as my main BMS for a large powerwall application. It is a simple software designed for balancing E-bike batteries. That being said I do like it so far and I myself is hoping someone more experienced will take a look at this in hope of customizing the parameters to meet our requirements. For now my plan is to use Batrium for the Power Rack. I will continue to use this "Smart BMS" to manage my Bench 48v pack.

In a previous post I provided screen shots of the 4 main screens. You can see all the updateable fields.

That inexpensive BMS board has an impressive amount of customization and control. Looks like it could be quite useful!

Probably would be best if I bought one myself and test it.... [emoji106]

Looking nice and neat! Would you mind posting some better pictures of the inverter? I'd love to see the model info sticker and the DC connectors, in particular!

Ooooh nooooo....... dont drop the 48V pack idea...

Cant say you are not taking thebetter route... those 14sxxpsystems are easy(er) to monitor and manage ( with Batrium bms that is.. ;) )
Still liked to see someone build a "48v pack in parallel" system just to see how it performs...

Don't worry wim, I'm still on that path ;)
