BASIC LITHIUM POLYMER BATTERY INSTRUCTIONS |
|
Dear customer, |
|
If you are unclear about any of the information presented here,
please contact us PRIOR to charging or discharging this battery. |
|
PLEASE NOTE -This is a VERSION 2 (V2) Common Sense RC Pack. The
polarity of the balance/charge connector is reversed from the
original Common Sense RC packs. Be sure to check the polarity of any
battery charger that you will use with this pack. Be sure to read our
limited warranty. |
|
|
|
THIS BATTERY MUST BE CHARGED BEFORE USE. |
|
1) Turn this page over (note from Big RC Models, this text is
provided below), and read the safety warnings on the other side. |
|
2) Inspect the pack for any obvious damage to the wiring or cells·
Contact us if the pack is damaged, even a little bit. |
|
3) Check the voltage of each individual cell in your battery pack.
Each cell should be around 3.7V (+/-0.3V), and the cells should all be
within 0.1 V of each other. If you are not clear on how to do this,
check out our website's Product Instructions page at
www.commonsenserc.com. or call us at 866-405-8811. Write down the cell
voltages on the included battery registration card. If the battery
pack is not within these tolerances, please contact us, and we will
exchange the pack for a new one. Taking the time to do this will save
everyone some hassle in the unlikely event that you have a pack that's
defective from the start. |
|
4) If necessary, solder a connector to the output leads of the pack
(see warnings below) |
|
5) Charge the battery pack, using either balancing charger or a
series charger in conjunction with a balancer. You must balance the
battery every time you charge it. Even small imbalances can lead to
overcharging of individual cells with a standard series charger,
resulting in damage to the pack, and potential fire hazard. You must
select the charge rate current that does not exceed 1C (one times the
capacity of the battery, unless otherwise noted). A higher setting may
damage your battery at 1 x capacity of pack. Generally speaking,
charging at even lower rates will extend battery life. 800 mAh: Charge
at or below 800mA 1500 mAh: Charge at or below 1.5 Amps 6000 mAh:
Charge at or below 6.0 Amps |
|
6) Check the cell voltages after the charge. The cells should be in
balance with each other, and no cell should exceed 4.2V. If any cell
is above 4.2V, Contact your charger's manufacturer, as the charger is
not functioning properly, and could cause a fire. |
|
7) Unless you are using the battery pack in a pre-approved
application (a stock vehicle we recommend the pack for, or a setup
from our EZ-Match system), use a wattmeter to test the current draw in
your application. Remember, this is an aftermarket pack, and unless
you test it, you don't know if you're pulling too much current out of
the pack. If you are planning to run the pack in more than one
application, measure each of them. Write down the current draw, or
preapproved application on your battery registration card. |
|
8) Register your battery pack with Common Sense RC. You have two
options for how to do this: |
|
a. use the Battery Registration tool on our website at
www.CommonSenseRC.com. |
|
b. mail in your battery registration card. |
|
9) Make sure that your ESC is set up for a lOW-VOltage-cutoff of
3.2V/cell or higher. If your ESC can't be programmed for this, install
an aftermarket LVC device like our CeliShield or LipoShield. |
|
10) Go run the pack! Enjoy it, and if you like it, tell your
friends! |
|
11) Allow the battery to cool down, and look over the pack to make
sure it hasn't been physically damaged, particularly if you've just
crashed! |
|
12) Charge and balance the pack |
|
13) Repeat steps 10-12 until you've had as much fun as you can
stand. |
|

Common Sense RC Lithium Polymer Battery Safety Warnings: |
|
By purchasing this battery, the buyer assumes all risks associated
with lithium batteries. We assume no liability for |
|
failure to comply with these warnings and safety guidelines. |
|
'Lithium Polymer batteries are volatile and can be very dangerous if
mis-handled, stored, charged or discharged |
|
improperly. Failure to read and follow thesejnstructions may result in
fire, personal injury, and damage to property |
|
'Store below 80' F and above 40' F whenever possible (not in direct
sunlight). Never store or charge a battery pack |
|
inside your car in extreme temperatures (100' F and above), since
extreme temperature could cause fire. Use caution |
|
to avoid puncture of the cells. Puncture of cells may cause fire. |
|
'If at any time you witness a battery starting to balloon or swell up,
discontinue the charging or discharging process |
|
immediately. Disconnect the battery and observe it in a safe place for
approximately 15 minutes. Dispose of the pack |
|
following the instructions below. Continuing to use a battery that has
begun to swell may result in fire. |
|
'00 not attempt to solder connectors to Lithium Polymer batteries
unless you have sufficient experience. |
|
Wire lead shorts can cause fire. If you accidentally short the wires,
the battery must be placed in a safe area for observation for
approximately 15 minutes. |
|
Additionally, if a short occurs and contact is made with metal (such
as rings on your hand), severe injuries may occur due to the
conductibility of electric current. |
|
|
|
If, for any reason, you need to cut the terminal wires, it will be
necessary to cut each wire separately, ensuring the wires do not touch
each other, or a short may occur potentially causing a fire. |
|
|
|
To solder a connector, remove any protective insulation on the red
wire and solder to the positive terminal of a connector, |
|
then remove any protective insulation on the black wire and solder to
the negative terminal of the connector. Be careful |
|
not to short the wire lead. If you accidentally cause the battery to
short, place it in a safe open space and observe the |
|
battery for approximately 15 minutes. A battery may swell or even
possibly catch fire after a short time. |
|
'Do not charge battery packs in series or parallel. Charge each
battery pack individually. Failure to do so may result in |
|
incorrect battery recognition and charging functions. Overcharging may
occur and fire may be the result. |
|
You must check the pack voltage before each charging session. Do not
attempt to charge any pack if the voltage per cell is less than 3.2 V. |
|
|
|
Example: Do not charge a 2-cell pack if below 6AV |
|
Do not charge a 3-cell pack if below 9.6V |
|
'Do not discharge battery to a level below 3.2V per cell under load.
Deep discharge below 3.2V per cell can dramatically |
|
deteriorate battery performance and will likely cause the battery pack
to become defective and un-usable. |
|
'Batteries that lose 20% of their capacity must be removed from
service and disposed of properly. For example, a |
|
2000mah battery that behaves as if it is only a 1600mah battery is
unsuitable for service. Dispose of it using the |
|
instructions below |
|
Lithium Polymer disposal instructions. |
|
1 )Discharge the battery to 0 volts. |
|
2)Puncture each cell and immerse in saltwater for 24 hours. |
|
3)Wrap the battery in a bag and place in an appropriate disposal
canister. |
|
4 )The pack can now be thrown in the garbage - there are no special
disposal |
|
requirements for Lipo batteries. |
