The battery builders club

I am currently lmao having trouble with my cheap-ass spim08hp welder packs, something is off with one? or all? of them I am not sure. I am trying some fresh packs and maybe I will lengthen the wires so that 3S3P does not give overcurrent like before.

Now we can be sure molicel cells cant be faked

1 and a half year old video for something that would just add cost to the cells?

I fiqured we would be seeing these by now…still waiting. Also good to know about XTAR using molicel as a legit rewrap

Is this normal? New cells P42A 12s8p. All cells were 3.53V and 3.52V. This is the furst charge.
Now number 5

this isnt normal. If group 2 is charging faster than the rest of them, it means the capacity of that group is lower. Perhaps a dead cell?

Or loose nickel

I’d bet on loose nickel, this is a nese pack right?

yes, when i wiggle the pack the voltages jump around so I think you may be right. I’m sure I double-checked all of :thinking:the connection

It should be within a 0.02V difference between p-groups as well as the cells that make up the p-group correct?

I believe that’s a reasonable variance for a decently used pack. From my experience(not much) new p42a’s should stay much closer than that, especially with a good bms.

setting the balance turn on voltage to 3.7V (default was 4.0V) is that a bad thing?
