Muchmore LiPo Batteries - Manual (Page 2)

IMPORTANT WARNINGS: Be sure to follow these important
warning statements regarding the charging of LiPo batteries:
• NEVER LEAVE A LIPO BATTERY UNATTENDED AT ANY
TIME WHILE BEING CHARGED!!
• NEVER charge a LiPo battery while it’s inside the model. A
hot pack could ignite wood, foam, plastic, etc.
• NEVER charge LiPo batteries at currents greater than the
“1C” rating of the battery (“C” equals the rated capacity of
the battery).
• NEVER allow LiPo cells to overheat at any time! Cells which
exceed 140°F (60°C) during charge can and USUALLY WILL
become damaged physically and possibly catch FIRE!! Always
inspect a battery which has previously overheated and do not
re-use if you suspect it has been damaged in any way.
• ALWAYS discontinue charging a LiPo immediately if at any
time you witness smoke or see the battery starting to swell
up. This may cause the battery to rupture and/or leak, and
the reaction with air may cause the chemicals to ignite,
resulting in fire. Disconnect the battery and leave it in a safe
fireproof location for approximately 15 minutes.
• ALWAYS charge a LiPo battery in a fireproof location,
which could be a container made of metal (such as an
ammunition box), ceramic tile, or a bucket of sand. ALWAYS
have an “ABC type” fire extinguisher available at all times.

CHARGING THE BATTERY

• NEVER charge LiPo batteries with a NiCd or NiMH peak
charger!
ONLY use a charger specifically designed for LiPo batteries
which can apply the “constant current /
constantvoltage” charge technique (cc/cv). MuchMore offers
several LiPo compatible chargers ( www.much-more.co.kr)
which can be found at your local retailer.
1. Use a charge lead that directly mates to the connector on the
LiPo battery. It is strongly recommended to use pre-assembled
charge leads which can be found at most hobby retailers. Hand
made connectors can be unreliable and hazardous, provid-
ing poor physical and/or electrical connections. Muchmore’s
“Docking Station”(#MR-SDS) is directly compatible with Much-
More LiPo batteries which have the 2-pin charge connector
(non-balanced packs).
2. Connect the charge lead to the charger first. Then connect
the battery to the charge lead. NEVER connect the battery to
the charge lead if the charge lead is not connected to the
charger! WARNING! Never allow a battery’s positive and
negative leads to accidentally touch each other. This will
result in a short circuit and cause permanent damage to
your battery and or charger.
b. For batteries having the BALANCING CONNECTOR: You
must know how many cells are in the battery pack, and then
choose an adapter lead which matches your pack. For
example, a 3-cell LiPo configured for balancing MUST use a
charge adapter which has enough wires to monitor the voltage
of all 3 cells in the pack (an adapter designed for 2 or 4 cells
will NOT work properly). A 2-cell LiPo configured for balancing
must use a balancing charge adapter that is designed for 2-cell
packs only, and so on. Failure to choose the proper balancing
adapter could result in improperly charged and improperly
balanced packs.
MuchMore “Cell Balancer” (#MR-SBL) is directly compatible
with batteries having the balancing connector.
a. For batteries having the RED 2-PIN CHARGE
CONNECTOR: Connect the red positive (+) lead to the
charger’s red positive (+) output jack, and the black negative (-)
lead to the charger’s black negative (-) jack. ALWAYS charge the
battery through the connector. NEVER charge the battery
through the connector which goes to the ESC. For safety
purposes, do not cut or modify wires on the battery in any way.
3. Set the charger’s output voltage to match the nominal
rated voltage of the entire LiPo battery pack. NEVER set the
charger to a voltage which is greater than the nominal
voltage rating of the LiPo pack or allow LiPo cells to
charge to greater than 4.20V per cell at any time!!
Overcharging LiPo cells usually will result in a permanent,
catastrophic failure in the LiPo cells which can result in
permanent damage to the battery and its surroundings, and
cause personal injury!
