It is just a panel meter. I use one to turn off my charger. It has worked fine

Problem is no one has actually proved that with experimentation. Not in any of

I have used ammeter for 2 years now. The voltage always end exactly the same.
The next day the pack is the pack is exactly 147 volts.
I have never seen any study done
I skip constant voltage. My cell voltage at the end of charge is 3.34 volts
after settling for several hours.
When I use cc - cv mode they settle to 3.38 volts.
You don't loose more than a couple miles range by skipping the cv mode.

Test Drive: Price cut for Chevy's
Here's my observation I received my cells and new the measured 3.3 volts. 16
months later when I put then in the vehicle they measured 3.298 and 3.297.

If you have a bike with no BMS and you are monitoring the cells that should be
all the data you need to decide if a BMS is necessary. Not what others tell you.
What are you observations of the cells

That was a very good summary. Cell balancing is something that was

If one wanted
We already covered how to tell is a cell has internal defects. You drain the
cell to 2.5 volts and then if the cell voltage rises it's good if it keeps
falling don't use it. I did think this up This is what NASA does. I read it in
one of their presentations. I can dig it up if you like.

Even Boeing burned up dream liners with a BMS.
Got any other argument besides everyone is doing it?

I just report what I observe. My cells don't self discharge. Only had one
reverse and as I said that was a loose connection.
I don't know of anyone who claims their cells went to zero sitting on a shelf.
Unless they were defective it should never happen. However, there's probably a
low
Li cells are not designed to have low self discharge. It is a matter of
physics. They just don't or I should say it is very very low and slows down
with ever charge cycle. What loss there is is due to electrolyte breakdown and
forming of the SEI layer, primarily.
