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.
5. DISCHARGING
All LRP Competition Car Line Hardcase LiPo batteries are capable of a maximum peak dischar-
ge current of 120C (120C/60C types), 110C (55C/110C types) or 80C (40C/80C types). The
special manufacturing technology of the LRP Competition Car Line Hardcase LiPo batteries
make these high discharge currents possible.
Be sure that the battery temperature is not below 18°C (65°F) if you run it in your model as the
high discharge load will hurt the performance and the cycle life of your battery if it is below
this temperature.
PLEASE NOTE: Always take care that the battery gets enough cooling when discharging it
with high discharge currents.
You have to take care, that the batteries do not get deep discharged. As soon as the battery
voltage falls below 3.3V per single cell, the battery pack gets damaged irrevocably. With 2S
packs, the discharge cut-off voltage under load is 6.6V. With 1S packs, the discharge cut-off
voltage under load is 3.3V. With 3S packs, the discharge cut-off voltage under load is 9.9V
(13.2V/4S). The battery voltage should never fall below these discharge cut-off voltages. If
your speed control does not have a special undervoltage protection for LiPo-batteries, you
have to stop your model early enough in order not to deep discharge the battery pack. The-
refore stop immediately as soon as you feel a rapid loss in power.
IMPORTANT: The max. temperature of the LiPo-battery during discharge must never exceed
65°C (150°F).
NOTE: If the batteries do swell or get thick after discharging them, it is a sign of overload
and/or deep-discharge. The battery pack gets damaged due to this and the max. perfor-
mance will get less. Swollen battery packs are not a product fault and therefore excluded
from the limited warranty.
6. SPECIAL NOTES FOR HANDLING
• Make sure to set your eletronic speed control cut-off voltage to the correct LiPo battery
voltage, depending on the battery you are using. A wrong cut-off voltage can lead to deep-
discharging the battery, which damages it battery irrevocably.
• Avoid short-circuits! Short-circuiting the battery results in very high currents, which dama-
ge the internal structure of a LiPo-battery. This leads to a loss of power and capacity.
• Never charge LiPo batteries without a balancer. Charging without a balancer can damage
the battery. Please note, that your limited warranty will void if you charge without balancer.
• Be sure, not to damage the outside of the LiPo-battery. The battery is only protected by
a heatshrink. The actual Lipo-cell is directly under this heatshrink. If the outer skin of the
cell gets damaged, the battery can no longer be used. Therefore take special care, that no
sharp objects like knifes, tools, carbon fibre edges or similar items can damage the hard-
case and/or the cells within it.
• When securing the LiPo-battery inside your model/device, you have to take care that the
LiPo-battery does not get damaged or warped in case of a crash. LiPo-batteries are less
mechanical resistant then NiMH-batteries in a metal can. Therfore pay special attention
that the LiPo-battery does not get damaged or warped by letting it fall down, hitting it,
bending it or by similar actions.
• Never charge several LiPo-battery packs at once with one charger. The different capacities
and charge levels can lead to serious overcharging of the battery, even if you are using a
charger with LiPo capabilities.
• Damaged packs cannot be used any longer. If the packs show signs of damage, are bent or
similar, do not use the packs anymore.
• The chemical reaction during charging and discharging a LiPo-battery is not fully rever-
sible. Due to that, LiPo-batteries loose capacity during their life-span. This is normal and
neither a manufacturing nor production fault.
DISPOSAL NOTE: Damaged packs or packs, which can no longer be used are hazardous
waste and have to be disposed of accordingly.
7. STORAGE !!!
For a storage over a longer period of time, we recommend to charge the battery up to 50%
of the nominal capacity. Therefore fully discharge the battery pack and then partially charge
it with a charge current of 1C for 30 minutes or charge it up to a voltage of 3.85-3.90V/cell.
In this condition, the battery can be stored at least 3 months at 25°C room temperature wit-
hout the need of recharging it. If the batteries are stored longer, be sure to make a complete
charge and discharge cycle every 3 months and partial charge it again for storage. We also
recommend this procedure before the first use in a model after the battery has been stored
for 2-3 months or longer.
ATTENTION: NEVER STORE THE BATTERY COMPLETELY EMPTY OR FULLY CHARGED.
Both will harm the battery and lead to swollen battery cells. A fully charged battery will
have the same negative effects as a completely discharged battery.
Even if you are using your battery regularly every week, always pay attention that the battery
is partially charged with at least 30% of the nominal capacity during storage. A partial charge
with 1C charge current for 20 minutes is sufficient in this case, if the battery was competely
empty before.
For storing, we recommned to use our LRP LiPo Safe Box (No. 65848). If you pay attention

8. INTERESTING FACTS ABOUT LIPO BATTERIES
• LiPo batteries shall only be charged at a temperature between 0-45°C. If this will not be
observed, the cycle life of the battery will be reduced drastically.
• The single cell open circuit voltage of a fully charged LiPo battery is 4.2V (4.35V/P5-HV).
The single cell open circuit voltage of a 50% partial charged LiPo battery is approx. 3.85V
(3.90V/P5-HV). The single cell open circuit voltage of an empty LiPo battery is approx. 3.3V.
• A voltage below 3.3V per cell without load is in either case harmful for a LiPo battery. The-
refore always avoid voltages below 3.3V per cell.
• It is not visible from the outside when a LiPo battery gets overcharged. The only way to
find this out is to measure the voltage of the LiPo battery. The battery does not heat up nor
does it swell when it gets overcharged. Therefore always check the battery voltage during
charging. If it exceeds the max. charging voltage stop the charging process immediately
and check all settings.
• We recommend to stop discharging a Lipo battery if the remaining capacity reaches 30%
of the nominal capacity. With this, LiPo batteries will have the max. possible cycle life. Real-
Life application showed, that the cycle life of LiPo batteries is reduced if the battery always
gets completely discharged. This phenomenon can be seen with all types of LiPo batteries.
