Thank you for the reply! Do you happen to have a full pdf of these instructions? Is there more to this document?Reading the instructions is not really the easiest, but these are from jbd. Once you get the hang of it, it makes sense. I still managed to mix up the balance leads a couple times before I got it right.

They did send this now that I've gone through more of my conversation with JBD.Thank you for the reply! Do you happen to have a full pdf of these instructions? Is there more to this document?
I truly appreciate the detailed explanation! Is there any way we could connect on Facebook or maybe I could do a video call or something if I’m stuck? I don’t want to mess this up haha. These things are expensive.They did send this now that I've gone through more of my conversation with JBD.
I think the wiring is on page 13. Then on page 14 it tells you which balance leads to connect together into one connection on a terminal or however you decide to do it.
So the big blue B- will go to the battery negative. (Mine goes to my shunt, shunt goes to the negative). Then from the bigger white balance lead plug, the first little wire (black 24awg) goes to the first negative (same negative that the b- went to). Then the next white will go to the first positive on that same first cell as you just put the black negative to. Follow the instructions after that to the 14th balance lead. Put the 14-18 together (I put all in one ring connection and crimped). Once you have them all connected, go through with a multimeter and make sure they step up the voltages in order. 3.2-6.4-9.6, ect to 51v. If it goes in order, you've wired it correctly. I also ring connectioned my last 2 red wires together on the last positive terminal.
My ring connectors were for 16-22 awg wires, so I just bent the end of the leads once and then crimped. It has worked so far with no issues.
It took me quite awhile to figure it all out, but I really just needed it explained in a way I could understand it. Pm me if you need more help and we can work out a way to connect.I truly appreciate the detailed explanation!

I have an iPhoneNo there is no shunt (battery monitor) included. Your picture is a fuse.
There is an app for the BMS. Do you have an iPhone or Android?

Thanks it looks like that is going to work for my phone. Do you know how I would attach that fuse that comes with the bms?![]()
Xiaoxiang BMS
With Xiaoxiang / jiabaida BMS Smart BMS you can build simple Li-Ion or LiFePo4 battery packs. For camping, car, solar or e-bikes. iOS app for Xiaoxiang / jiabaida BMS (JBD-SP15S001 / JBD-SP05S002) allows you to monitor voltage of the cells, total capacity, charging/discharging current and...apps.apple.com
I don't have an iPhone, but try this.
I took a chance with the vendor that used to be on here, for junctek (funny name I know). Initially I had some issues, but then I contacted the vendor and there were firmware updates that I didn't know about that fixed the issues. Now it seems to be pretty cool and isn't too expensive.Do you guys have a shunt you recommend?

It's a kg140F. $55 on AliExpress and the vendor is super responsive to help with issues. lee@junteks.com
I figured that the lifepo4 have a discharge rate of up to .5c, which for the 280k's would be 140 amp. My inverter could only do 125 amp. There was no 150 smart BMS I could find at the time for a reasonable price, so I went with the 200. I just didn't want to bottle neck at the bms with a 100 or 120 amp.Awesome thank you for that. Is there a reason why I should have a lower or higher amperage BMS? Why is it good or bad to have a 200amp BMS?
