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, carb
on 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 th
a
t you only attach the
new plugs to the p
ower-wires directly. Under no ci
rcumstances you
r
allowed to solder directly on
the
tabs of the LiPo-cell
s
. Please note, that there´s the possibility to void your limited warranty
when changing the plug system.
•
Never charge several
LiPo-battery packs at on
ce with one charger. The different capacities and
charge levels can lead to
serious overchar
ging of the battery,
even if you are using a charger wit
h
LiPo
capab
ilities.
•
Damage
d packs cannot be used any l
onger. If the packs show signs of damage, are bent or similar,
do not use the packs anymore.
•
The ch
emical reaction dur
ing charging an
d
discharging a LiPo-batter
y is not fully reversible. Due
to that, LiPo-batter
ies 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.

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.
Additio
nall
y 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 u
se a
2mm g
old
plug
socket, which acts as a cell connection between
the two cells in the pack. This
connection can
be used for bala
ncing the cells aswell.
Special balancers or cert
ain chargers use this balancing port to perfec
tly
condition and equ
alize the
ind
ividual 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. There
fore fully discharge the battery pack and then
p
artially charge it with a char-
ge curre
nt of 1C for 30 minutes.
In this co
ndition, the battery can be stored at leas
t half a year at
25°C room temperature without the need of recharging it.
For a storage over a short perio
d 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 wi
th 1C
charge current for 10 minutes is sufficient in this case, if the battery was competely empty before.
If you pay attenti
on to
the above me
nt
ioned notes, you can en
joy your NOSRAM VTEC LiPo
-battery
for a very l
ong 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 ou
r NOSRAM LiPo RX
Regulator 6V/5A (#95000)
to connect a
RX-only pack to your rec
ei-
ver. This regulator reduces the voltage to a safe level of 6V and
will be connec
ted d
irec
tly
betwee
n
the NOSRAM VTEC LiPo RX-only battery and the receiver
.

All NOSRAM VTEC LiPo-batteries can be charg
ed with a maximum current of
1C* (0.8C* for RX/TX-
packs).
For charging, only use chargers, which are specially designed and developed for LiPo-bat-
teries. These chargers charge the battery with th
e max. current till the battery reaches the max.
charging voltage. The charger then reduces the charging current until the battery is fully charged.
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
LiPo-batteries do not heat up dur
ing charging. It is normal, that the battery still
has ambient temperature when it is fully charged. If the battery heats up dur
ing charging or warps,
immed
iately stop charging it
.
The max
imum charging volt
age for each sin
gle LiPo
-
cell is 4.20V. If the battery reaches this voltage,
the charg
e curre
nt has to be lowered. This is automati
cally don
e by the charger. If the charge cur-
rent reaches 0.05 - 0.1C
*, the battery is fully char
ged. All NOSRAM VTEC Li
Po-batteries
consist of
multi
ple LiPo-cells. You can see the max
. charging voltage in the table bel
ow.
NOSRAM VTEC 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 dischar-
ging 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.
We recommend the following settings for charging our NOSRAM VTEC LiPo-batteries:

.
All NOSRAM VTEC LiPo-batteries (except the RX/TX-packs) are capable of a maximum peak discharge
current of 25C. The special manufacturing technology of the NOSRAM VTEC LiPo-batteries make
these high discharge currents possible.
The
continous
discharge current for all NOSRAM VTEC LiPo-batteries (except the RX/TX-packs)
is 15C.
Please note:
RX-/TX
-only packs can only be used for the typical application as receiver (RX-only) or
transmitter (TX-only) pack. They are not suited for high discharge currents
!
You have to take care, that the batteries do not get deep
discharged.
As soon as the battery volta-
ge
falls bel
ow 2.80V per single cell, the battery pack gets damaged irrevocably.
With 2
S
packs, the
discharge cut
-off voltage is 5.6V, with 3S packs it i
s 8.4V an
d with 4S packs
the discharge cut-off voltage is 11.2V.
The battery voltage should
never fall below these discharge
cut-off voltages.
If your spe
ed 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 fe
el a rapid loss in power.
IMPORTANT:
The max. temperature of the LiPo-battery during discharge must never exceed 60°C
(140°F).
