dear friends,
I am currently working on a lipo battery pack for my racing board.
I have 6 x 2s lipo batteries which I like to use as a 12s block.
To balance the cells, I plan to connect a 12s balancer between the lipos.
the products I got in front of me:
please correct me if I am doing something stupid here!!! I dont like to burn my house…
thank you for any help.

Hello Folks,
One of the things that got to me early on when getting into esk8 was how a simple process of connecting a smart BMS to a couple of 6S LiPo cells should be and the number of forum posts that covered this topic in a complex way. So while there are a few great posts going around tackling this subject I wanted to put my own spin on it in an effort to see if I can simplify things a little.
I’ve included a circuit diagram and a video walkthrough of me doing this process live! Yep, you …
Alright folks, have some time on my hands so decided to make this guide.
We are going to be wiring 4x 3s lipo batteries to a smart Bluetooth LTT bms (available on https://www.lithiumbatterypcb.com/ ) in charge only to make a 12s lipo. The goal here is to be able to monitor individual cell voltages from a smartphone and charge the batteries from a charge port on the enclosure and not have to take them out every time.
This is the best solution I have come up with for flying with my board and tak…
Main thing is how to wire it when it has 13 wires.
0 is Neg I get that its also black.
Red is Positive or what I assume to be 12 or the end of the pack but RED is 13th wire.
The balance wires have 11 WHITE.
So with RED and BLACK I have 13.
I assume to go from BLACK to 1,2,3,4,5,6,7,8 etc and make the last be the RED one.
Im staring to think I should be going from RED then leaving the last BLACK wire on the LIPO open for the
BMS connection to a C-.
Hey guys i just picked up a 12s bms and im wanting to hook it up to my 6s lipos so i dont need to carry a lipo charger around wiht me on group rides, plug and run is what im after. i got an 8amp charger sitting around from my lion pack but i was wondering if their was anyone in melbourne who could wire up a bms with connectors for 2 6s lipo packs so i could plug and play.
True. I usually pull the extra metal plug out of the connector so that it can’t possibly touch anything. I use lipo packs with BMS units and I don’t like actually cutting the real balance connectors off, so I solder a male side on the other end, thus I can pull the pin out of the male side to forego that connection

that is a massive answer, thank you @glyphiks for the links.
(I did some search here in the forum but seem like I have to improve my search skills)
@glyphiks ok after reading the suggestd posts, I think that my wiring is correct.

Your diagram looks correct to me.
What’s a little more concerning is that your BMS appears to only be an active balance board and is seemingly missing some other useful features that help keep our batteries safe.
Features & details
This inductive active balancer: only compensates for adjacent batteries whose voltage difference is greater than 0.2V.
If the battery error voltage is above 0.1V, the scale work will be started until the error is stopped at 30mV.
The smaller the current, the static power consumption does not exceed 20uA.
The built-in improved MOS with extremely low internal resistance, the balancing current is 0-1.2A and the battery voltage difference is smaller.
Working voltage: 2.2 V - 4.5 V. High quality
Personally I’d recommend using something like the JBD/LLT smart bms. This one is my favourite at the moment

glyphiks:
LLT smart bms
the link is not available in germany, says alibaba…
Its not the same one that I linked, but it will do the same job
This one will offer several charge protections and also allow you to monitor the individual voltage and other information of your cells via bluetooth.

ok. nearly done now.
i did 2x 3x2s
when the new bms arrives, i will change it.
