I ran into a discussion on this charger here .
It seems someone at Maha seems to think that unprotected Li-Ion cells are not suitable for use with this charger.
"We do not recommend using the
MH-C777 Plus-II
with TP or Kokam Li-Polymer batteries. The reason is because
Li-Polymers are very unstable when charging or discharging, and a protection
circuitry is required to regulate voltage and current; it also allows the battery
to interact with the charger. This circuitry is not built in either TP or
Kokam batteries, which increases the chance of fire or damage.
I'm aware that the MH-C777Plus-II specifies that it will also charge
Li-Polymers. However, it is only safe to charge them with the
circuitry.
This is not only true for our charger, but all chargers out there."
Since Li-Poly cells share the same chemistry as Li-Ion cells, I am assuming that this would also apply to our use as well.
I know several people use this charger and I am wondering if there have been any problems with it observed while charging unprotected Li-Ion cells?
On the other hand, it could be that this customer service person is un-informed...
