@MikeKC can I solder to the tabs that go to the flex pcb up the side? Obviously I cut the strip.MVC-003F MVC-004F

@Inwo
I think they are aluminum so soldering would be difficult. Maybe pop-vivit or drill a hole and thread a wire thru and solder the wire to the wire after twisting it tight?
No sure exactly what you are trying to accomplish.
What I did was attach at each cell location (tab) of the aluminum strips with copper wire and ran those to my BMS.

How did you connect them? I thought maybe they were zinc and you just soldered the balance wires the the original location. Did you solder on the flex board?

These tabs:

Correct, if you pull the blue foam out you will find that there is a gap where the strip is factory welded to the cell. I wrapped the end of BMS lead around the flex strip, twisted it tight, soldered it and put hot glue over the top. I ran each lead back down the battery to the BMS. Basically recreating the aluminum strip with wire.

$3,000 as shown. Making some 14s next, for new Polaris gems and rangers…
Glad to help someone build their own. Be prepared for a couple weeks of stress.
