Which Tesla Model S batteries have the plug to hook up a balance cable?

That video is useless, He's just talking about wheels and TOU.

OP here's what you're looking for:

it replaces the OEM Tesla BMS board with one where you can plug in a standard cell checker/balancer.

As a side note to keep in mind, you don't have to replace the OEM boards. Since they already have balancing and monitoring capabilities, all you have to do is capture the data and give them 5v.

You can go the pre-assembled route and buy a SimpBMS ($300) which will connect to the OEM board and give you expansion for contactors, pre-charge, etc. Or you can buy the EVTV controller ($2500) which comes with the software and contactors already built.

If you'd rather go with the DIY route you can build your own controller using an Arduino Due or a Teensy board and load Collins software

I built my own powerwall by taking apart a 60kW battery pack so let me know if you need any details on the process.

Well guy, it does say to start here. Watch the plethora of other videos.

And at the rate that Jack talks, and talks, and talks it'll take him a year to get the necessary info. Not to mention that OP asked about the plugs on the modules so he could hook up a BMS to it. Most of jacks videos are about using his own controller and the OEM boards not using a third party BMS hooked up directly to the module cells.

As a matter of fact OP, if you haven't already bought your modules HSR motors sells them with custom board that breaks out the leads into a standard 7 pin checker balancer plug.

That being said, unless you already have a BMS take a good look at using the OEM BMS boards as you'll be throwing away a really good balancer/monitoring system which is included in the module.
 
My DIY Powerwall is up and running. I've got two modules in series charging from a Midnite 150 with an AIMS 48v inverter doing the work. This is day two and I had a restless night's sleep thinking about imbalanced cells.

My modules each came with half an OEM balance cable with the Molex connector but I can't find pinouts anywhere. Imagine you're looking through the back of the Molex with module oriented vertically and the poles at the top, and you would see the following wire colors:

Rd Bl Gn Bl Rd
Gy Yl Gn Yl Gy

Pulling back the sheathing, the wires are in twisted pairs: Gn/Yl and Bl/Rd with the Grey's going singleton.

Does anybody know what each pin does?

Thanks much,
Chris
 
I found this showing how to wire modules to communicate: Intermodule and Partial BMS. I understand the VCC(+) and Gnd(-), but wonder what to do with the transmit, receive, and fault signals. Will says he uses this Tenergy 5-in-1 on his site here, but the pins on it are for 7 modules plus a ground (and a servo test function).

Can someone please help me understand how to wire the module outputs VCC, GND, TX, RX, and FAULT to the Tenergy's 7 module input?
 
You can't use the Tenergy on this connector; here's some info about the connector and com protocol : https://github.com/collin80/TeslaBMS

However you can use the Tenergy on the connector with the balance wires (there's also some wires leading to temp sensors on the same connector but you can just ignore them), you need to remove the OEM BMS to access it.

Hey! This is what I'm trying to do currently, but I can't figure out what that connector cable type is. It's 15 pins and I can't find anything like that available anywhere.
Does anyone know what that connector type is called and where I can find a 15 pin version so I can make an adapter to connect to the tenergy?
