into one 7.4V pack. Once wired in series, connect the battery’s
open 4mm positive (+) terminal to the LiPo balancer’s red (+)
lead, and the battery’s open 4mm negative (-) terminal to the
balancer’s black (-) lead. Connect the adapter’s smaller (2mm)
male terminal to the small jack that is attached to the jumper
lead as shown. IMPORTANT: You MUST charge saddle packs as
one 7.4V pack. Do NOT charge the 3.7V modules separately.

2S-4S Hardwired LiPo Packs: For charging 2S-4S hardwired
LiPo batteries, the balance lead will need to be connected to
the proper balance adapter and the power wires will need to
be connected to the charger. It is imperative that the proper
balance adapter is chosen for charging.

2S LiPo Receiver Packs: For charging 2S LiPo receiver
packs, the balance lead will need to be connected to the
proper balance adapter and the power wires will need to be
connected to the charger via radio jack or universal charge
lead adapter. It is imperative that the proper balance adapter
is chosen for charging.
8. NEVER leave the room where the battery is until charge has
fi nished.
IMPORTANT: NEVER allow a battery’s positive and
negative leads to accidentally touch each other, as
a short-circuit condition will result and permanently
damage the battery and/or charger. Disconnect the battery and
remove input power from the charger immediately if the battery
begins to swell or becomes hot!! Be sure to wear protective gloves
when moving the battery in case it has become hot.
IMPORTANT WARNINGS FOR CHARGING LIPO BATTERIES:
■ NEVER allow a LiPo cell to exceed 4.20V maximum at
any time.
■ NEVER allow LiPo cells to exceed 140°F (60°C) during
charge, as they can and USUALLY WILL become
damaged and possibly catch FIRE!!
■ NEVER allow a LiPo to continue charging if the battery
begins to swell or smoke begins to emit from the pack,
as this is an indication the pack is damaged and a
catastrophic failure could occur soon. Disconnect the
battery and leave it in a safe, fi reproof location for
approximately 1 hour.
■ NEVER allow a LiPo to continue with the charge process
if the charger fails to recognize full charge. Disconnect
the battery immediately, as pack failure could result.
■ NEVER attempt to charge a battery that has previously
overheated, discharged below 2.50V, or which has been
damaged in any other way. Dispose of the battery.
■ LiPo cells should be charged about once per year at a
minimum to prevent over-discharge.
■ LiPo batteries should be stored with about 30%-50%
of capacity.
■ ALWAYS keep out of reach of children.
Discharging LiPo Batteries
WARNING!! NEVER allow TrakPower LiPo cells to
discharge below 2.5V per cell as permanent cell damage
could result. This can also result in some chargers not
recognizing the battery upon recharge, preventing the battery
from being charged again. ALWAYS make sure batteries are
physically and electrically undamaged before charge or discharge.
1. When powering an ESC:
a. Do NOT use an ESC unless it’s LiPo compatible.
b. Follow the ESC’s instructions carefully to set the proper low
voltage cutoff point for the battery. As an extra measure of
safety and to maximize the lifespan of the TrakPower battery,
it’s recommended to not allow the battery to discharge
below 3.20V per cell.
c. ALWAYS disconnect LiPo batteries completely from
electronic speed controls when not in use to prevent
accidental over-discharge.
2. When using a battery discharger:
a. Choose an isolated, fi re-
proof area to discharge
the battery as explained
on page 2.
b. Choose a LiPo compat-
ible discharger which
has balancing capabili-
ties. Or, use a LiPo com-
patible discharger in
conjunction with a separate LiPo balancer.
c. Set the discharge cutoff voltage to 3.20V to 3.40V per cell for
TrakPower LiPo batteries. NEVER discharge a LiPo to 2.5V or
below at any time as permanent failure will result.
d. Set the discharger’s output current to an appropriate value
for the battery.
e. Connect the battery’s main lead and balancing lead to the
discharger as described in the discharger’s instructions.
ALWAYS connect a charge adapter lead to the charger BEFORE
connecting the battery to the charger.
f. If possible, as another extra safety measure, use a discharger
that also includes a temperature monitoring function that can
stop charge if the battery exceeds a specifi ed temperature.
Set the discharger’s maximum temperature to 115°F (46°C).
g. NEVER leave the room where the battery is being discharged.
