1. STOCK SPEC AND LCG LINE
Along with the standard Competition Car Line hardcase battery line, LRP introduces
two brand-new Competition battery lines that are specially developed for the needs of
current racing classes.
The LCG - Low Center of Gravity line has been designed to get the maximum out
of your racing cars. These batteries are tailor-made for specific racing classes and a
must-have for serious racing drivers.
The LCG Touring car battery pack will lower the center of gravity of your TC car by
using a lower hardcase and lighter cells. This will result in higher conering speed and
faster reactions on steering inputs.
The LCG Saddle Pack and LCG Shorty batteries are tailor-made batteries for 1/10
Off-Road cars. They feature a lower hardcase together with a much lighter cell weight
that will make your Off-Road car jump better, corner faster and create more traction.
They will also give you the possibility to use additional weights that can be shifted
around in your car to meet your personal driving style.
ATTENTION: The LCG Saddle Pack and LCG Shorty battery packs are designed to be
used in 1/10 Off-Road cars on slippery surfaces. Do not use thes types on high grip
surfaces or other racing classes.
The Stock Spec line has been specially developed for stock racing classes. It features
the highest possible voltage output for maximum speed and acceleration. The low
internal resistance of these batteries will give you more punch and higher topspeed
than the standard batteries. This is essential for stock racing classes where capacity is
nothing and power is everything.
The Stock Spec line features a standard Sub-C size battery pack for Touring Car racing
classes and a Shorty pack for Off-Road racing classes.
ATTENTION: We do not recommend to use the Stock Spec line batteries for modified
racing classes as the power characteristics of these batteries might be to aggressive.
1. Connections
All LRP Competition Car Line Hardcase LiPo packs have 4mm gold plug sockets built
into the battery pack. These power connections have to be used for standard charging
and for all applications in the model/device. Be sure to always take care of the right
polarity, which is shown on the hardcase of the battery, as a wrong connection will
damage your battery and your speedo. While soldering, take care that you don´t do
any short circuits and that all wires are well insulated.
Additionally to the 4mm gold plug sockets, all LRP Competition Car Line Hardcase LiPo
packs, except the 1S packs, use a 2mm gold plug socket, which acts as a cell connec-
tion between the two cells in the pack. The 3S packs are equipped with a so-called
XHR-Balancing-port. This connection can be used for balancing the cells aswell. This
connection is used for balancing the LRP Competition Car Line Hardcase LiPo pack.
Special balancers or certain chargers use this balancing port to perfectly condition
and equalize the individual cells inside the pack. Please check the user manual of the
balancer/charger in order to know how the battery needs to be hooked up. For perfect
charging and conditioning of the batteries, we recommend our LRP PULSAR TOUCH
COMPETITION (No. 41556).
NOTE: The Balancing-port shall not be used for the standard use in the model/device.
Only use the 4mm gold plug sockets to power your model/device.
For perfect conditioning of your LRP Competition Car Line Hardcase LiPo pack, we
recommend the use of our LRP PULSAR TOUCH COMPETITION charger (No. 41556).
Together with the 2S LiPo Hardcase charging wire (No. 65821) or the 1S LiPo Hardcase
charging wire (No. 65829) and one of our LRP LiPo Safe Box (No. 65848), your battery
will always have the best possible performance.

halve.
2. Charging
Due to new and special manufacturing technologies, all LRP Competition Car Line
Hardcase LiPo batteries can be charged with a maximum current of 3C*. For charging,
only use chargers, which are specially designed and developed for LiPo-batteries. The-
se chargers charge the battery with the max. current till the battery reaches the max.
charging voltage. The charger then reduces the charging current until the battery is ful-
ly charged. This charging method is called CC/CV (Constant Current/Constant Voltage).
For charging the LRP Competition Car Line Hardcase LiPo batteries, we recommend
our LRP PULSAR TOUCH COMPETITION (No. 41556).
ATTENTION: Under no circumstances use NiMH/NiCd-chargers or chargers, that are
set to NiMH/NiCd mode, for charging LiPo-batteries! These chargers do not reduce the
charging current and therefore ultimately lead to overcharging the battery! Only use
chargers that have an automatic end of charge cut-off and are specially designed for
radio controlled model batteries. Do not use timer chargers.
LRP Competition Car Line Hardcase LiPo batteries batteries do not heat up during
charging. It is normal, that the battery still has ambient temperature when it is fully
charged. If the battery heats up during charging or warps, immediately stop charging
it. A Balancer which monitors the voltage of each single cell is mandatory during the
charge of LiPo batteries.
ATTENTION: Never charge your LiPo battery without a balancer directly connected
to the balancing port of your battery, unless your charger is already equipped with a
balancer. Always charge your battery outside of your model!
The maximum charging voltage for each single LiPo-cell is 4.20V. If the battery rea-
ches this voltage, the charge current has to be lowered. This is automatically done
by the charger. If the charge current reaches 0.05 - 0.1C*, the battery is fully charged.
Some LRP Competition Car Line Hardcase LiPo batteries batteries consist of multiple
LiPo-cells. You can see the max. charging voltage in the table below. We advise the
following settings for charging our LRP Competition Car Line Hardcase LiPo batteries
batteries:
Cell configuration
LRP Competition Car Line - 1S - 3.7V
LRP Competition Car Line - 2S - 7.4V
<4000mAh
LRP Competition Car Line - 2S - 7.4V
>4000mAh
LRP Competition Car Line - 3S - 11.1V
PLEASE NOTE: You can use your LRP Competition Car Line Hardcase LiPo battery
several times a day. However be sure, that the battery has completely cooled down to
ambient temperature, before re-charging it again.
LRP Competition Car Line Hardcase LiPo batteries batteries do not have a memory
effect and only a very low self-discharge rate. Therefore you can also charge batteries
with a partial charge in them, without the need of discharging the pack before. Partially
charged packs can be stored over a long period of time, without getting damaged.
Please also see the „Storage" section for further reference.
* C=Nominal capacity of the battery. E.g. with a nominal capacity of 7000 mAh (7.0Ah),
the battery can be charged with a max. current of 21.0A.
