I wish it was hot glue. It looks like he used crazy glue. I have already pulled the pack apart to the bad row. I am going to pull the whole pack apart and see what cells are salvageable. Then put it back together correctly with a BMS. Those cells are like $7 each.

I think this pack is a lost cause. I can save 1/2 the pack but the rest are glued together. Looks like I would need about 35 of these LG cells to make the pack again. Joy.

So I tried to put a hobby charger on bank 7 and it says connection break. So what I just pull the nickel strips up and separate bank 7 and replace it with fresh cells? The cells are LGDBM361865 P181F291A1 /2 any idea where to find them? I also think they are glued together.

Whats weird is when I plug the pack into the charger 84v and test voltages again they are all around 3.5 except that rom 7 measures around 21v.

1-3.33v 2-3.49v 3-3.50v 4-3.49v 5-3.49v 6-3.50v 7-0.155v 8-3.48v 9-3.49v 10-3.46v 11-3.50v 12-3.49v 13-3.49v 14-3.49v 15-3.50v 16-3.49v 17-3.49v 18-3.47v 19- 3.49v 20-3.50v Looks like 7 is dead.

I split the battery as you can see below. I put the negative lead on the negative charge cable and measured the cells as you can see. 3.33v 10.33v 17.33v 21.10v 28.09v 35.1v 42.1v 49.1v 56.1v 63.1v 66.8v at the Andersen connector

not yet. I can pick one up.

So I just picked up this Tomos Moped conversion and was told the battery is dead. I test it and it has 66v on it. The issue is there is no BMS unless it is built into the controller somehow. Any advice how to proceed? I am under the impression that I can just add a bms and seal up the battery...
