Sorry if this has been asked before.
I'm starting out and I like the idea of salvaging laptop batteries, but now I'm wondering, are they reliable?
Let's say this is my scenario:
1. I get my hands on old/dead laptop batteries.
2. I take it apart and harvest the 18650 cells.
3. Those that are below 1V (let's call them bad cells), I parallel charge them or I somehow resuscitate them.
4. The bad cells that I manage to get back up to 4V+, I include with the rest of the good cells.
5. I create 7S packs out the cells.
Question: wouldn't the bad cells that turn bad when being inside a laptop go bad again?
Wouldn't that bad cell affect the good cells in the series, for the same reason it became bad in the first place?
Is it because the use conditions inside a laptop is different than an off-grid solar system?
Will the charge controller and BMS prevent that scenario?
Thanks in advance!
