How to be safe
As a general rule, if you store them 30% charged in a cool, safe place away from anything flammable, use only a Lithium charger (both LiPo or Lithium Ion chargers will work fine) charge them slowly and under supervision, discharge them at the rated C-ratings with proper ventilation / cooling, treat them nice and don't do anything crazy like shorting them out or crushing them, they will not cause any issues and last a very long time.
The full legal disclaimer is below:
Warning: procedures, which if not properly followed, create the probability of property damage, collateral damage and serious injury. For the purposes of this document, Li-ion will be described as “Batteries”.
Handling and storage
-Never alter, puncture or impact Batteries or related components.
-Do not directly connect the terminals with metal objects. This will short-circuit Batteries, resulting in heat and electrical discharge.
-Never store loose Batteries together, the Batteries’ terminals may contact one another causing a short circuit.
-Never expose Batteries to extreme temperatures or direct sunlight. The temperature range must be between 40-120F (4-49C).
-Always verify voltage of Batteries that have been out of service for greater than six (6) months.
-Always charge/store Batteries in a non-conductive, fireproof container or bag.
-For best results, store Batteries at approximately 1/2 of the capacity listed on the batteries’ label.
Before the First Charge
-Make a visual and physical inspection of Batteries for any damaged or loose leads or connectors, damaged packaging, or other irregularities which may cause a short circuit and eventual fire.
-Verify that the positive terminal of the Batteries is connected to the positive terminal of the charger. Confirm polarity with a voltmeter if unsure.
-Check the voltage of Batteries using a voltmeter to make sure Batteries have the voltage of the capacity listed on Batteries’ label.
Always refer to your charger’s manual for correct procedures and safety information. In addition to your charger's manual, the warnings and guidelines listed below must be followed to avoid possible property damage and injury.
-Always use a compatible balanced mode charger, specifically designed for the chemistry of battery you are using.
-Always charge Batteries in an open area away from flammable materials, liquids and surfaces.
-Never charge Batteries inside of the model.
-Never charge Batteries that are hot to the touch (above 100F) DO NOT handle batteries until they are cool.
-Always set the charger to proper cell count and/or voltage listed on Batteries’ labels.
-Never charge at a rate greater than 1/2C (Half the capacity of Batteries in amp hours)
-Always check the voltage of Batteries before each charge session in order to ensure they are at or above the minimum safe starting voltage. If starting voltage is below recommended levels than Batteries have been over discharged or have experienced a failure and should NOT be charged.
-Never overcharge Batteries beyond the capacity listed on Batteries’ labels.
If an any time Batteries become damaged, hot or begin to swell, discontinue charging or discharging immediately. Quickly and safely disconnect the charger. Then place the Batteries in a safe, open area away from flammable materials in an approved Li-Po bag to observe. After one hour, remove the Batteries from service. Do NOT continue to handle attempt to use, or ship the Batteries. Failure to follow these procedures can cause damage to Batteries, personal property or cause serious injury. Damaged or swollen Batteries can be unstable and very hot. DO NOT touch Batteries until they have cooled. Dispose of Batteries in the manner required by your city, county, state or country. In the event of a fire, a Class D, dry chemical fire extinguisher must be used.
-Never discharge Batteries at amperage rates higher than specified on Batteries’ labels.
-Never allow the temperature of Batteries to exceed temperatures advised by the manufacturer.
-Never discharge batteries to voltage below which they are rated by the manufacturer when measured under load (connected to the vehicle or a charger capable of discharge). Batteries discharged to a voltage lower than the lowest approved voltage may be damaged, resulting in loss of performance and potential fire when Batteries are charged.
Additional Guidelines and Warnings
-In the event of a crash, always quickly and safely disconnect and remove Batteries from the model. Then follow the previously listed safety procedures.
-In the internal contents of Batteries come into contact with your skin, wash the affected area(s) with soap and water immediately. If it comes into contact with your eye(s), flush them with generous amounts of water for 15 minutes and seek medical attention.
