ASG 11.1v 900mah 15C lipo battery - mini Tamiya

LiPO Warning & Usage Disclaimer

IMPORTANT!!! READ MANUAL in its entirety before use.
Take extra precautions when handling Lithium Polymer (LiPo) batteries, as they require different safety measures compared to NiMH or NiCd batteries ! Failure to follow these instructions can result in severe permanent damage to battery, cause serious personal injury, or lead to a fire.
 
LiPO batteries are intended to be used with compatible radio controlled (R/C) models and airsoft guns only. Any damage caused by misuse or modifications will void your warranty and can cause serious injury.
By purchasing this product the buyer/user agrees that they have read and understood the safety precautions printed in this document and accepts full responsibilities of these risks. By agreeing, the user/buyer does not hold the seller, its distributors, or its retailers responsible for any accidents, injury to persons, or property damage that may occur. If buyer/user does not agree with these conditions, please return the battery in its original condition immediately to the place of purchase.

General Safety Guidelines :

• NEVER use a NiCd/NiMH charger to charge LiPo batteries. Only use chargers designed for Lithium Polymer (LiPo) batteries.
• NEVER store LiPo batteries in any location that exceeds 40-80° F (e.g. in a car, garage, or in the sun)
• NEVER leave charging batteries unattended. Keep watch on the charging process & react to any potential problems that may occur.
• NEVER let the battery’s positive and negative leads to touch. This can cause the battery to short and lead to a FIRE. If for any reason you need to cut the terminal wires, it will be necessary to cut each wire SEPARATELY, to make sure the wires do NOT touch each other.
• NEVER charge a swollen or ballooned battery (even if swollen upon purchase). Continuing to charge a battery that has begun to swell will result in a fire.
• ALWAYS inspect the battery to make sure there are no signs of damage, deformity, or swelling before charging. If there are, STOP charging the battery and follow the proper procedure to dispose of the battery.
• ALWAYS charge batteries in a fireproof container and away from combustible material. Do NOT charge on surfaces that can catch fire – this includes: wood, cloth, carpet, or in the application’s device.
• ALWAYS store LiPo batteries in cool, dry places between 40-80° F.

If the battery reaches high temperatures in the event of an R/C Model crash, follow these steps:

• Disconnect battery immediately from the device
• Place it in an open non-flammable area
• Watch it for approx. 30 minutes from a safe distance
• If the battery appears to be stable (no signs of damage or swelling) proceed to put it back into your device and continue using with caution.
• Keep LIPO batteries out of reach of children or pets.

Avoid Over-Discharging LiPo Batteries :

Over-discharging—continuing to use a LiPO battery even when it is almost completely drained or below its minimum voltage level—can cause permanent damage to the battery. The damage caused by this can be INTERNAL battery damage and will not always be visible. However, internal damage can eventually lead to a FIRE when attempting to re-charge it at later times. This problem can be easily and commonly overlooked in Airsoft applications because there are no indicators that the battery is at a low voltage and should be removed to be re-charged. Please exercise proper understanding and usage of the battery in your application to prevent safety issues or injuries and to prolong battery life.

Charging Batteries :

• ALWAYS visually inspect LiPo battery for any damaged leads, connectors, shrink wrap, swelling of cells, or other irregularities before charging or using.
• Do NOT use if you find any of the above issues with your pack.
• Before installing or changing the connector, check the voltage of the pack using a digital voltmeter (not your charger).
• NEVER leave charging batteries unattended. Constantly watch the charging process and react to any potential problems that may occur.
• ONLY charge batteries in a fireproof location. Never charge on wooden surfaces, cloth, carpet, or materials that can catch fire.
• Allow the battery to cool down to ambient temperature before charging.
• Do NOT charge multiple battery packs in series. Charge each battery pack individually. Failure to do so may result in incorrect battery recognition and charging functions. Overcharging may occur and result in FIRE.
• When selecting the cell count or voltage for charging purposes, select the cell count and voltage as it appears on the LiPo battery label. Selecting a cell count or voltage other than the one printed on the label will cause improper charging rates that can lead to fire.
• As a safety precaution, confirm the information printed on the battery is correct. Example: The label on a 2-Cell battery pack in series will read – “7.4V” – You must select 2-Cell for charging. The label on a 3-Cell battery pack in series will read – “11.1V” – You must select 3-Cell for charging.
• You must check the pack voltage before charging. Do not attempt to charge any pack if open voltage per cell is less than 3.3V.  For example: Do not charge a 2-cell pack if below 6.6V,  Do not charge a 3 cell pack if below 9.9V

In most cases the charger's charging current should not exceed 1C, unless otherwise noted. A higher setting may damage the battery & cause a fire.

C-rating is a standard which defines a battery's operating current based on its capacity.  1C is the current it takes to approximately fully discharge a battery in 1 hour, and is simply defined by dropping the "h" in the pack's capacity (e.g. 1C for a 1000mAh LiPo battery is 1000mA, or 1A).  The examples below demonstrate how to figure out the proper charging current for different Packs:    

• 900 mAh LiPo Batteries -> Charge at or below 900 mA
• 1300 mAh LiPo Batteries -> Charge at or below 1300 mA, or 1.3 A
• 2200 mAh LiPo Batteries -> Charge at or below 2200 mA, or 2.2 A

Battery packs should NEVER be over-discharged at any time. Specifically, over-discharging on the first use will ruin the battery permanently before you get to fully enjoy it. Be extremely careful not to over-discharge new packs:

• Battery Maintenance & Handling
• NEVER disassemble existing LiPo packs to mix with other LiPo cells/packs.
• Use a high quality Lithium Polymer charger – a poor quality charger can be dangerous.
• Do NOT discharge battery to a level below 3V per cell under load. Deep discharge below 3V per cell can deteriorate battery performance.
• Use extreme caution and protect LiPo batteries to avoid puncture of the cell – punctured cells can cause fire.
• It is recommended to use a Low Voltage Detection Device to warn users when the battery pack voltage is too low. This ensures longer battery life & prevents dead batteries.

Storage & Transportation :

• NEVER store batteries near an open flame or heater.
• Do NOT expose battery pack to direct sunlight (heat) for extended periods of time
• Storing battery at temperature greater than 170°F for extended periods of time (more than 2 hours) can cause damage to battery and a possible fire.
• For long term storage, do NOT store batteries fully charged; it is recommended to fully charge and then discharge it to 50-60% of their capacity before storing.
• Store battery at room temperature between 40 and 80°F for best results.
• When transporting or temporarily storing in a vehicle, temperature range should be greater than 20 °F but no more than 150°F.

Battery Life & Disposal of LiPo Batteries :

• Rechargeable LiPo batteries do NOT last forever. Batteries that have lost 20% of their initial capacity should be removed from service and disposed of properly. If at any time you see any physical damage in a LiPo battery such as swollen cell, split, or tear in the cell’s foil covering, STOP usage immediately and dispose of battery.
• Proper Disposal Procedure of LiPo Batteries: Use the discharge function of your charger to discharge the battery to 1V/Cell or lower. Make sure the wire leads are fully insulated and soak battery in salt water (1/2 cup of salt per gallon of water) for 2-3 days. Then wrap battery in a bag for disposal.
