Exactly, so the folks who are quoting their experience with expensive factory direct cells, or with batched/matched cells as typicaly, are either being intentionally obtuse, or just downright malicious.
There is more than one way to top balance, and for those skilled/experienced its a non issue. These other methods are good, but they probably require an extensive writeup for the masses.
Curious comment. I have been helping people install off-grid DIY Lifepo4 packs for a decade now, and haven’t come across any problems with individually charging cells before assembling, or using power resistors to drain high cells when a pack is series assembled for the first time.
The last few packs i have assembled from used mismatched cells i have used an active balancer in combination with a BMS until the cells are matched.
You say these methods require extensive write up or training, yet the so called simple method of connecting your entire pack in parallel with no failsafe in the event of a charger malfunction is apparently fine?
Look at where all the problems are occurring before you decide which advice is malicious.
