1. connections
All NOSRAM VTEC X-treme Race 65C Hardcase Lipo packs already 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 VTEC X-treme Race 65C 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 65C
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.
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 65C Hardcase Lipo pack, we recom-
mend 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
65C 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 65C 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 65C Hardcase Lipo battery. This user
guide contains important 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 65C
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.
2. charging
Due to new and special manufacturing technologies, all NOSRAM VTEC X-treme Race 65C 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 65C Hardcase LiPo batteries, we recommend our NOSRAM
STEALTH TOUCH EVOLUTION (No. 91555).
ATTENTION: Under no circumstances use NiMH/NiCd-chargers 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 65C 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
current reaches 0.05 - 0.1C*, the battery is fully charged. All NOSRAM VTEC X-treme Race 65C
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 65C
Hardcase Lipo batteries:
Cell configuration
NOSRAM VTEC X-treme Race - 65C - 1S - 3.7V
NOSRAM VTEC X-treme Race - 65C - 2S - 7.4V
NOSRAM recommends these charge settings for optimum performance:
Cell configuration
NOSRAM VTEC X-treme Race - 65C - 1S - 3.7V
NOSRAM VTEC X-treme Race - 65C - 2S - 7.4V
Please Note: You can use your NOSRAM VTEC X-treme Race 65C 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 65C 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, 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 5300mAh (5.3Ah), the battery can be charged
with a max. current of 15.9A.
3. discharging
All NOSRAM VTEC X-treme Race 65C Hardcase Lipo batteries are capable of a maximum peak
discharge current of 100C. The special manufacturing technology of the NOSRAM VTEC X-treme
Race 65C 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 65C 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
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).
