1. CONNECTIONS
All NOSRAM VTEC X-treme Race Hardcase Lipo packs have 4mm gold plug sockets built into the bat-
tery 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 VTEC X-treme Race 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. This connection is used for balancing the NOSRAM VTEC X-treme Race 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 VTEC X-treme Race Hardcase Lipo pack, we recommend
the use of a Balancer together with the NOSRAM LiPo Hardcase balancing wire (#95805). The
balancing wire allows to plug in the balancer directly without the need of additional soldering work.
For best possible performance and safety, always use a balancer when charging your LiPo battery.

Dear Customer,
thank you for your trust in this NOSRAM product. By purchasing a NOSRAM VTEC X-treme Race Hardcase
Lipo battery, you have chosen a high-performance battery for your RC model. Please read the following
instructions to ensure, that your NOSRAM VTEC X-treme Race Hardcase Lipo battery always works up to
your full satisfaction.
LiPo-batteries need special treatment and care. Please read the following instructions carefully before
you start using your NOSRAM VTEC X-treme Race Hardcase Lipo battery. This user guide contains impor-
tant notes for the installation, the safety, the use and the maintenance of this product. Thus protecting
yourself and avoid damages of the product.
Proceed according to the user guide in order to understand your NOSRAM VTEC X-treme Race Hardcase
Lipo battery better. Please take your time as you will have much more joy with your product if you know it
exactly.
This user manual shall be kept in a safe place. If another customer is using this product, this manual has to
be handed out together with it.

Due to new and special manufacturing technologies, all NOSRAM VTEC X-treme Race 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 Hardcase LiPo batteries, we recommend our NOSRAM
STEALTH TOUCH EVOLUTION (No. 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 overcharging the battery!
NOSRAM VTEC X-treme Race Hardcase Lipo 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.
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 cur-
rent reaches 0.05 - 0.1C*, the battery is fully charged. All NOSRAM VTEC X-treme Race Hardcase
Lipo 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 VTEC X-treme Race Hardcase
Lipo batteries:
NOSRAM VTEC X-treme Race - 1S - 3.7V
NOSRAM VTEC X-treme Race - 2S - 7.4V
NOSRAM recommends these charge settings for optimum performance:
NOSRAM VTEC X-treme Race - 1S - 3.7V
NOSRAM VTEC X-treme Race - 2S - 7.4V
Please Note: You can use your NOSRAM VTEC X-treme Race 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 VTEC X-treme Race Hardcase Lipo 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, wit-
hout the need of discharging the pack before. Partially charged packs can be stored over a long pe-
riod 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 6900mAh (6.9Ah), the battery can be charged
with a max. current of 20.7A.
All NOSRAM VTEC X-treme Race Hardcase Lipo batteries are capable of a maximum peak discharge
current of 110C (55C/110C types) or 100C (50C/100C types). The special manufacturing technology
of the NOSRAM VTEC X-treme Race 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 currents.
You have to take care, that the batteries do not get deep discharged. As soon as the battery vol-
tage falls below 3.00V per single cell, the battery pack gets damaged irrevocably.
With 2S packs as the NOSRAM VTEC X-treme Race Hardcase Lipo batteries, the discharge cut-off
voltage under load is 6.0V. With 1S packs, the discharge cut-off voltage under load is 3.0V The bat-
tery voltage should never fall below these discharge cut-off voltages.
2mm Balancing port
If your speed control does not have a special undervoltage protection for LiPo-batteries, you have
single cell connection
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 overlaod 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.
