BMS is everything for lithium charging safety... I built a charging
station for charging cells using ceramic tiles.. They get extremely
hot if they burn.

There has to be at least a dozen different "flavors" of lithium

Never ever ever charge lithium batteries unattended. Build yourself a
box out of cinder blocks for future charging.

Couple of our guys came to check some thing at the shop today,
the OSP crew ready room was full of smoke.
Our horizontal directional drills use sondes in the drill head
for tracking purposes. We recharge the batts every time they
come back to the shop.
The batts we use are smaller than normal sonde bats so they fit
into an adapter, sabot type of thing.
The industry standard is double C cells, but the vibrations are
such that normal C cells will give you intermittant service. So
most use a special 3 volt battery that is probably just 2 c cells
welded with heat shrink.
Our new locators and sondes use a voltage a bit higher than most
3.3 volt lithium. They like 3.6 volts I believe. So the smaller
batteries are adapted to fit the sonde, but the charger for them
requires the adapter.
They really should make the charger such that the larger batts
cannot be put in it.
Just glad we didn’t have a fire. It did blow the corner of a
piece of shelving.
