Few videos of the JK Inverter BMS working with it.

@Rodney hillbrant did you get this working? I'm in the same spot.

haha any suggestions? I just ordered JK BMS suggested in this post

It's OK. The soc is not accurate and the 6000 xp doesn't do any float.

Also, when you hit 100 percent on battery, the 6000xp goes to grid thinking the bms is calling an overload... this is extremely hard to stomach. 100% soc and using grid for no good reason.

Overall it's pretty lame but ok if you never hit 100 percent.

Suggestions? Not besides the diy victron shunt "fake bms".
It's not an easy or off the shelf option tho.

Oh darn it, we are too late in preventing him in getting one.

its okay, I have cancelled it, thank you so much about the warnings about JK BMS being abandoned.


So it seems like the approach is Victron smartshunt + custom setup to convert VE.DIRECT to PYLON?

It is most of the same issues.
The soc calculating is great and the once and a while you hit 100 you can manually change the victron shunt to read 97 or so. It works a lot better for me but I'm still searching

Hopefully jumping in here is ok.

I currently have one EG4 LifePower4 V2 Lithium Battery – 48V and a single 6000XP. I want to increase battery storage as I tend to run low daily before solar picks up. I have two strings 1680W and 3000W input. I know my initial setup was low on battery capacity and am ready to fix that now. I would like to build a diy battery with 16S 304Ahr cells. I almost ordered a JK BMS but now am hesitant. If I want to keep the rack battery and add a 15kw diy battery is there a preferred BMS? I may add a second 15kw diy battery as well and would consider repurposing the existing EG4 server rack battery if it makes things easier.

Thanks, and if I need to make a new thread, let me know. My title was going to be the exact same so I thought this would be better.

For optimal performance, it is strongly recommended to add another EG4 battery if expanding your battery bank. Mixing EG4 batteries with other brands is not recommended.

jk bms and diy batteries work fine with 6000xp, just put the latest firmware on the bms.

Why, what optimizations do you lose?

Mixing EG4 batteries with other brands is not recommended.

If they are the same chemistry and voltage what's it matter? Just run open loop or set one battery to communicate and the others not.

They want to sell batteries and give no pfvcks to anyone who doesnt obey.

Kidding kinda, BUT

I am pretty sure they know just the absolute minimum about what they are selling and are playing it safe.

That's a pretty useless post...

You can't blame them.
I wouldn't recommend other Electrical contractors to my customers, either.

But you know what you are selling.

True that.
