1. CONNECTIONS
• 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.
• Be sure, not to damage the outside of the LiPo-battery. The battery is 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 battery.
• 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-bat-
tery does not get damaged or warped by letting it fall down, hitting it, bending it or by similar
actions.
• If you want to change the plug system of your LiPo-battery, take care that you only attach the
new plugs to the power-wires directly. Under no circumstances your allowed to solder directly on
the tabs of the LiPo-cells. Please note, that there´s the possibility to void your limited warranty
when changing the plug system.
• 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, LiPo-batteries loose capacity during their life-span. This is normal and not a manufactu-
ring nor production fault.
Disposal note:
Damaged packs or packs, which can no longer be used are hazardous waste and have
to be disposed accordingly.
2. SPECIAL NOTES FOR HANDLING
Dear Customer,
thank you for your trust in this NOSRAM product. By purchasing a NOSRAM VTEC Lithium-Polymer
battery (LiPo-battery), you have chosen a high-performance battery for your RC model. Please read
the following instructions to ensure, that your NOSRAM VTEC 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 Lithium-Polymer 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.
of
of
Proceed according to the user guide in order to understand your NOSRAM VTEC Lithium-Polymer
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.
All NOSRAM VTEC LiPo-batteries come with properly sized power-wires incl. plugs. The special X-tre-
me Race hardcase packs already have 4mm gold plug socket built into the battery pack. These power
connections have to be used for standard charging and for all applications in the model/device.
Additionally to the power connections, all NOSRAM VTEC LiPo-batteries are equipped with a so-called
EHR-Balancing-port. This EHR-Balancing-port can be used to condition and equalize the individual
cells inside a NOSRAM VTEC LiPo-battery pack. The X-treme Race hardcase packs use a 2mm gold
plug socket, which acts as a cell connection between the two cells in the pack. This connection can
be used for balancing the cells aswell.
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
power-wires incl. plugs to power your model/device.

3. STORAGE
NOSRAM VTEC LiPo-batteries do not have a memory effect and only a very low self-discharge rate.
Therefore these batteries can be stored over a longer period of time without special treatment. You
only have to take care, that the batteries do not get stored completely empty.
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 char-
ge current of 1C for 30 minutes. In this condition, the battery can be stored at least half a year at
25°C room temperature without the need of recharging it.
For a storage over a short period of time, you also have to pay attention, that the battery is partially
charged. Never store the battery completely empty.
Even if you are using your battery regularly every week, always pay attention that the battery is
partially charged with at least 20% of the nominal capacity during storage. A partial charge with 1C
charge current for 10 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 VTEC LiPo-battery
for a very long time.
Due to the nominal voltage of 7.4V of all RX-only packs, these battery packs cannot be connected
directly to the receiver. Standard receivers and servos work with a voltage of 6V and therefore will
not work properly or get damaged.
You need our NOSRAM LiPo RX Regulator 6V/5A (#95000) to connect a RX-only pack to your recei-
ver. This regulator reduces the voltage to a safe level of 6V and will be connected directly between
the NOSRAM VTEC LiPo RX-only battery and the receiver. Please see the instruction manual of the
NOSRAM LiPo RX Regulator 6V/5A (#95000) for further reference.
