Dear Customer,
thank you for your trust in this LRP product. By purchasing a LRP 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 LRP 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 LRP 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.
Proceed according to the user guide in order to understand your LRP 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.

USER MANUAL
• 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 he-
atshrink. 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-battery 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
manufacturing nor production fault.
Disposal note:
Damaged packs or packs, which can no longer be used are hazardous waste and
have to be disposed accordingly.

CAPACITY
All LRP VTEC LiPo-batteries come with properly sized power-wires incl. plugs. These power-
wires have to be used for standard charging and for all applications in the model/device.
Additionally to the power-wires incl. plugs, all LRP VTEC LiPo-batteries (except the „RX-only“-
packs) are equipped with a so-called Balancing-port. This Balancing-port can be used to condi-
tion and equalize the individual cells inside a LRP VTEC LiPo-battery 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 power-wires incl. plugs to power your model/device.
For the standard applications, the Balancing-port is not necessary. Nevertheless do never cut-
off or remove the Balancing-port plug.

3. STORAGE
LRP 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
charge current of 1C for 30 minutes. In this condition, the battery can be stored at least half a
year 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 LRP VTEC LiPo-battery
for a very long time.
4. USE OF RX-ONLY PACKS
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 LRP LiPo RX Regulator 6V/5A (#45000) to connect a RX-only pack to your receiver.
This regulator reduces the voltage to a safe level of 6V and will be connected directly between
the LRP VTEC LiPo RX-only battery and the receiver. Please see the instruction manual of the
LRP LiPo RX Regulator 6V/5A (#45000) for further reference.
