I would only use a K&W charger on a forgiving PbSO4 wet cell pack.
There's nothing wrong with the K&W charger per se. It's crude, but it works.
The problem is that you can't use it *alone* to charge batteries that
are easily damaged by overcharging. That includes AGMs and gels, as well
as lithiums. You have to add a BMS of some kind to stop the charger from
overcharging.

The principal defect in a storage battery is its modesty. It does not
spark, creak, groan, nor slow down under overload. It does not rotate.
It works where it is, and will silently work up to the point of
destruction without making any audible or visible signs of distress.
