JK-PB2A16S-20P wiring diagrams

[sd_dracula]

I just picked up this BMS but cannot find any proper user guides/diagrams for it just yet, I suppose it is quite new.
Will be building a 16s2p battery with it when the cells arrive.
Just wondering on the wiring of the balance cables if there is a diagram for it to ensure I am connecting correctly.
It has 4 sets of cables labelled 1 to 4, cable 1 has 2 black wires (thermistor) and 5 red cables, cables 2-4 have the 2 black wires and 4 red cables.
I think I can just about make sense of it but I'd like to be 100%



B0 would be the main battery negative and then the rest B1-B16 are all the cell positives?

B0 means connecting to the Cell 1 negative, see below link of JK website:

Yes, and you'll notice the second B8 written on the bms shell does not connect to any wire on the balance lead harness.

But notice that there are 2 B8 connections. Use the plug with the NC (no connection) on the 3r socket from the right since B8 is wired from the second plug. This will then give you a B0 connection on the first plug with all its wires populated.

I'm not a clear ... Do I need cut off this black end and connected to first - cell ? Looks to me like a temp sensor .. pleas help

That black duo wire with the clump at the end is the temp sensor.

 

[lukM]

That means I need connect only this red wire to + positive cell 1-16 ... Thank you for your response

First red wire B0 goes to cell 1 negative, second red wire B1 goes to cell 1 positive.
