Wago carriers

[John Frum]

I made a 8s 24 volt nominal battery out of the Shenzen Basen 280ah Eve cells.
Since the cell terminals are pretty delicate I used 10 awg wires for balance leads so that I could top the cells individually and even do per cell capacity testing without breaking the pack.


I cross connected the leads using a terminal block which meant I would have to disconnect the balance leads in order to charge/discharge individual cells. It also a presented a short circuit opportunity which continually bugged me. After the pack was put in service in a spot with less than ideal physical access I decided to change over to Wago 221-613's which mitigated the short hazard and meant that I didn't have to disconnect the bms to charge/discharge individual cells.


Problem solved but its a dog's breakfast

Wago Canada was kind enough to send me some samples.
I used the 221-510 din mount carrier to bring order to the chaos.

I should mention that it was a really awkward position to work in.
Connecting the wires to the wagos is made easy because I can move the wago into the light.
Connecting the wagos to the the carrier was easily accomplished basically by touch and sound. The wagos click when they lock into the carrier.
The carrier clicks when it locks on to the din rail.

Just to be clear I wouldn't use 10awg if I were to do it again.
I would use 12awg and then I could use 221-413 connectors and their respective carriers.
That way everything scales down.

You might also look into the Dinkle modular terminal blocks for DIN rails. I really like the way they work.

Those work with the little copper "comb" busbars?

Is this what you'd be wanting?

That would work.
I would then cut them to make 9x 3 pin busbars.
