Charging LiPo Batteries

WARNING!! Charging LiPo batteries poses a risk of
FIRE!
NEVER treat LiPo batteries in the same manner
as other battery types. Misuse and overcharge can

quickly result in LiPo cells swelling and/or getting hot which could
lead to VIOLENT EXPLOSION, FIRE, PERSONAL INJURY, AND/OR
PROPERTY DAMAGE! NEVER leave lithium batteries unattended
while being charged! It’s strongly recommended to have a Class
“D” fi re extinguisher nearby when charging a LiPo battery. Do
NOT use water or fi re extinguishers other than a “class D” to put
out a burning LiPo battery. Failure to follow all care and handling
instructions properly could result in quick, severe, permanent
damage to the batteries and all surroundings!! ALWAYS make
sure batteries are physically and electrically undamaged before
charge or discharge.

1. IMPORTANT! Choose an isolated, fi reproof area to charge

the battery. NEVER place the charger or battery on or near
flammable or combustible objects during the charge
process. Keep away from carpets, wood, paper, plastic,
cluttered workbenches, etc. Do NOT charge batteries in
the model, nor inside an automobile. Placing batteries
inside an army surplus ammunition can, ceramic fl ower
pot, or on a large concrete surface is recommended.

2. Use a LiPo compatible

charger that includes
balancing capabilities,
or use a LiPo compatible
charger in conjunction
with a separate LiPo
balancer. NEVER use a
NiCd or NiMH charger on
LiPo batteries!

3. Set the charger’s output voltage to EXACTLY match the nominal

rated voltage shown on the battery label.

4. Depending on the charger, set the charger’s charge current or

pack capacity to the appropriate level:

a. Some chargers require the setting of the actual charge

current. It’s recommended to charge TrakPower batteries at
the 1C level as shown below. WARNING: Make sure to
heed all warnings listed in these instructions if charging
at currents greater than 1C.

b. Instead of entering the

actual charge current
value, some chargers
require entering the
rated capacity of the
battery pack to be
charged into the
charger’s programming,
whereby the charger will then automatically set the charge
current value.

WARNING!! NEVER enter a capacity or voltage value
into the charger that is higher than the value specifi ed
for the battery! Failure to follow this warning can cause

permanent damage to the battery, charger, and the surroundings
as a result of FIRE, and cause personal injury!!!

5. If possible, as another extra safety measure, use a charger that

also includes a temperature monitoring function that can stop
charge if the battery exceeds a specifi ed temperature. Set the
charger’s maximum temperature to 115°F (46°C).

6. Connect the battery’s main lead and balancing lead to the

charger as described in the charger’s instructions. ALWAYS
connect a charge adapter lead to the charger BEFORE
connecting the battery to the charger.

7. Diff erent battery types require diff erent balance adapters.

Failure to choose the proper balancing adapter could result
in improperly charged and improperly balanced packs. Please
see the diagrams below for information regarding diff erent
confi gurations and types.
