1. CONNECTIONS
All NOSRAM X-treme Race 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 NOSRAM X-treme Race Line Hardcase LiPo packs, except the 1S
packs, use a 2mm gold plug socket, which acts as a cell connection between the two cells in the pack. The 3S packs
are equipped with a so-called EHR-Balancing-port. This connection can be used for balancing the cells aswell. This
connection is used for balancing the NOSRAM X-treme Race 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 NOSRAM STEALTH TOUCH
EVOLUTION (#91555).
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 NOSRAM X-treme Race Line Hardcase LiPo pack, we recommend the use of our
NOSRAM STEALTH TOUCH EVOLUTION (#91555). Together with the 2S LiPo Hardcase charging wire (#95816) and
one of our NOSRAM LiPo Safe Box (#95820), your battery will always have the best possible performance.

2. CHARGING
Due to new and special manufacturing technologies, all NOSRAM X-treme Race 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. These 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 fully charged. This charging method is called
CC/CV (Constant Current/Constant Voltage).
For charging the NOSRAM X-treme Race Line Hardcase LiPo batteries, we recommend our NOSRAM STEALTH TOUCH
EVOLUTION (#91555).
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 over-
charging the battery!
NOSRAM X-treme Race 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, im-
mediately 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.
The maximum charging voltage for each single LiPo-cell is 4.20V. If the battery reaches 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 NOSRAM X-treme Race 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 NOSRAM
X-treme Race Line Hardcase LiPo batteries batteries:
Cell configuration
NOSRAM X-treme Race Line - 1S - 3.7V
NOSRAM X-treme Race Line - 2S - 7.4V
NOSRAM X-treme Race Line - 3S - 11.1V
Please note: You can use your NOSRAM X-treme Race 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.
NOSRAM X-treme Race 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.

3. DISCHARGING
All NOSRAM X-treme Race Line Hardcase LiPo batteries are capable of a maximum peak discharge current of 110C
(55C/110C types), 100C (50C/100C types) or 80C (40C/80C types). The special manufacturing technology of the
NOSRAM X-treme Race Line Hardcase LiPo batteries make these high discharge currents possible.
Please note: Always take care that the battery gets enough cooling when discharging it with high discharge cur-
rents.
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. 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. Therefore 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. performance will get less. Swollen battery packs are not
a product fault and therefore excluded from the limited warranty.
4. SPECIAL NOTES FOR HANDLING
• Avoid short-circuits! Short-circuiting the battery results in very high currents, which damage 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 hardcase 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 reversible. Due to that, Li-
Po-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.
5. 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 half a year at 25°C room temperature without the need of recharging it.
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.
If you pay attention to the above mentioned notes, you can enjoy your NOSRAM X-treme Race Line Hard-
case LiPo batteries for a very long time.
6. 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. The single cell open circuit voltage of a 50%
partial charged LiPo battery is approx. 3.85V. 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. Therefore 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.
