The MRC Super Brain 969 Pro advertises it is Lithium compatible.
"This powerful charger has an ability to deliver 4.5 amps per channel when
using DC input. Now you can charge two batteries of different voltages or
types simultaneously, or charge one battery while discharging another. For
pro users, the 969 Pro has a variety of settings for optimal charge.
AC/DC delta peak charger with patented MicroPeak Technology
Charges NiCd, NiMH, Li & Pb batteries"

B. CHARGING LITHIUM ION-POLYMER BATTERIES
Never leave batteries unattended when charging. Monitor the temperature of
the battery occasionally during the charge cycle. If batteries become hot,
disconnect immediately.
Because of the volatile nature of Lithium batteries, great care must be
taken when charging these cells. If improperly or over charged, the is the
risk that the battery will explode or catch fire. Please follow instructions
and/or recommendations from battery manufacturer when selecting proper
charge rate.
You should always select 5mV peak threshold for all Lithium Ion/Polymer
batteries. You should also start with a fully discharged battery and do a
"capacity" charge as stated above in step 8. However, do not enter a
capacity higher than the rated capacity of the battery or damage may occur.
If you do not begin with a fully discharged battery, then you will have to
estimate the remaining capacity in the battery. We recommend that you use a
charge rate at no higher than half (0.5 times) the rated capacity (example
for 6OOmAH battery the charge rate = 0.5 x 600 or 0.30 amps). Also, be
careful not to discharge the battery too low (3 volts per cell), or damage
to the battery may occur. We recommend that you use a discharge rate no
higher than 0.2 amps.
LITHIUM BATTERIES DO NOT HAVE A PEAK, IF THE CHARGE IS NOT TERMINATED THE
VOLTAGE JUST KEEPS RISING UNTIL THE BATTERY SELF DESTRUCTS IN MANNER THAT
COULD CAUSE A FIRE. IF THE USER DOES NOT CORRECTLY ESTIMATE THE AMOUNT OF
CAPACITY REMAINING IN THE BATTERY AT THE BEGINNING OF CHARGE OR THE CAPACITY
HAS DIMINISHED WITH USE, A SERIOUS AND HAZARDOUS SITUATION WILL EXIST.
