Help ID these cell's/BMS

[EvanC]

Been looking at DIY banks for awhile now, and found some cells and a BMS for very cheap locally. Kind of an estate sale type deal.

They are relatively low capacity, but will suit my needs for a small project just fine for now. Seller claims brand new never been used.

My main question is, is this a decent BMS to use, and does anyone know where I can find a manual or some type of resource that can explain how to connect this BMS to the 8 cells properly? And how will I go about connecting to the BMS to program the settings? I googled the part number without much luck. From my search I feel like it's a discontinued model.

Also, I don't think the seller has bus bar's for interconnecting the cells. Any good idea's on sourcing bus bar's, or perhaps idea's/resources on making my own?

Planning to wire together 8s for a 24v bank.

Thanks.

Wiring: My guess is blue is to battery, and black is to load.
The black, white, and red wires go in order with each cell. Red to + on last cell, black to - on first cell, and each white to + in sequence.

Maybe some help here:

JBD/Xiaoxiang BMS Apps List

There are so many apps for the Jiabaida (JBD)/XiaoXiang BMS, I thought it might be helpful to post them all to one thread. Here are free the ones I've found so far. iOS: This is the official app, linked directly from the manufacturer, jiabada.cn's support page...

did you try to search for "xiaoxiang bms"?

Thanks for the links.

Yes I searched, and found many that visually look just like this one, but couldn't find this exact one anywhere. But other than the listed pack voltage and current output rating, I can't tell the difference between any of the models, and I don't know enough about them to know if there are vast differences in programming/connectivity/capability.

I for sure have a lot more reading to do.

Is it safe to assume the one in my picture will connect via bluetooth? (Do they all connect via bluetooth...?)

I think you need the Bluetooth adapter for it to work. JBD/XiaoXiang BMSs usually don't have Bluetooth built in internally, but rather use an external adapter like this, connected to the UART port:

Bluetooth Module for Smart BMS

Note: These are only compatible with our 100amp Smart BMS. The 300a Smart BMS already has this installed. They will not work with the 30amp standard BMS. Use the Xiaoxiang App to integrate to our BMS units via bluetooth. There are some connection issues mainly with certain Android phones which...
