Common Sense RC LiPo Batteries

Treat your LiPo Batteries properly and they will last much longer

 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.  
 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 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
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 Limited Warranty:

 •This warranty does not cover internal damage to the battery pack due to overcharging, deep discharging, or excessive discharge current.  
Common Sense RC Limited Warranty:
In order to be eligible for warranty exchange, the user must follow the initial setup instructions above, and the pack must be registered with Common Sense RC .
• This warranty is pro-rated over the life of the battery. The following table details exchange costs for warranty replacements.
Time since purchase Cost for warranty exchange
0-3 months No charge
3-6 months 40% of original purchase price
6-9 months 55% of original purchase price
9-12 months 75% of original purchase price
More than 12 months 85% of original purchase price
·As a courtesy to our customers, we will also exchange any physically damaged battery pack for a new one at 85% of the original purchase price.
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.
