Lipo Battery Safety

WARNING: You must read and understand before charging or using your lithium polymer battery. Failure to read and follow the below instructions may result in fire, personal injury and damage to property if charged or used improperly. Nova Hobby Inc. , our distributors/dealers and employees assume no liability for failures to comply with these warnings and safety guidelines. By purchasing this battery, the buyer assumes all risks associated with Lithium Polymer batteries. If you do not agree with these conditions, return the battery immediately before any use.

The following terms all mean “Lithium Polymer” (LiPo,LiPoly).

General Guidelines and Warnings:

   1. Lithium Polymer (LiPo) batteries have very specific charging requirements and MUST only be changed by specific chargers designed to charge lithium polymer batteries. Do not use a NiMH or NiCd charger - Failure to do so may lead to fire, explosions and toxic smoke inhalation, which may result in personal injury and property damage.

   2. Never leave charging LiPo batteries unattended. When charging LiPo batteries you should always remain in constant observation to monitor the charging process and react to potential problems that may occur. Battery observation should occur in a safe area and away from any combustible material. 

   3. It is your responsibility solely to assure the charger you purchased works properly. The LiPo charger you’re using must be able to handle the cell count of the battery you are charging. Always monitor charging process to assure batteries are being charged properly. Failure to do so may result in fire.

   4. Always discontinue charging a LiPo batteries immediately if at any time you witness smoke or see the battery starting to swell or balloon. This may cause the battery to rupture and/or leak, and the reaction with air may cause the chemicals to ignite, resulting in fire. Disconnect the battery and leave it in a safe, fireproof location and observe it for 15 minutes.

   5. Never, under ANY circumstances let the positive and negative battery leads touch. It can lead to cell ballooning, cell damage or fire or an explosion. If for any reason you need to cut the terminal wires or solder a connector, be careful not to short the wire lead. If you accidentally short the lead, please leave it in a safe, fireproof location and observe it for 15 minutes.

   6. If LiPo batteries are involved in a crash or are otherwise damaged, you must remove LiPo batteries for observation and place in a safe, fireproof location and observe it for 15 minutes. Never charge LiPo batteries that has been punctured or damaged in a crash.

   7. Modifications to the LiPo batteries in any manner will immediately void warranty. The user agrees to accept all responsibilities of these risks, responsible for any accidents, injury to persons, or damage to property.

   8. LiPo batteries should be charged within a temperature range of 0 degree Celsius to 40 degree Celsius. Outside this temperature range may experience leakage, heat generation or cell damage and possibly catch fire! If LiPo batteries become overheated, disconnect it from the charger immediately.

   9. Never charge LiPo batteries inside your car, on home furniture or wood floor/carpet, or anywhere near flammable material.

   10. ALWAYS make sure that metallic objects, such as wristwatches, bracelets, or rings are removed from your hands when handling LiPo batteries. Accidentally touching battery terminals to any such objects could create a shortcircuit condition and possibly cause severe personal injury.

Charging Process:

   1. Make a visual inspection of the LiPo batteries. Inspect them to ensure that there is no physical damage or swelling as those are signs of imminent failure. If any damage to the LiPo batteries or leads is found, do not attempt to charge the LiPo batteries.

   2. Never leave charging LiPo batteries unattended.

   3. Charge LiPo batteries in a fireproof location, which could be a container made of metal (such as an ammunition box), ceramic tile, or a bucket of sand.

   4. Let LiPo batteries cool down to ambient temperature before charging. If the battery becomes increasingly hot,  stop charging or discharging immediately.

   5. 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 lab el may result in overcharging and fire. As a safety precaution, please confirm that the information printed on the battery is correct. For example: If a battery label indicates that it is a 3 cell battery (3S), its voltage should read between 11.4 and 11.7 volts. This battery must be charged as a 3 cell battery (peak of 12.6V).

   6. ALWAYS check voltage before charging and subsequent charges. Do not attempt to charge any pack if open voltage per cell is less than 3v.

For Example: Do not charge a 2-cell pack if below 6v.

   7. You must select the charge rate current that does not to exceed 1C (one times the capacity of the battery). A higher setting may cause fire. The below chart is calculated at 1 x capacity of pack. For Example:  800 mAh: Charge below 800 mA. 

Storage & Transportation:

   1. Store LiPo batteries at room temperature between 5 degree Celsius and 30 degree Celsius for best results. Temperatures exceeding 70 degree Celsius for greater than 1 hour may cause damage to battery and cause a fire..

   2. Do not expose LiPo batteries to direct sunlight (heat) for extended periods or place in direct contact with any liquids. If batteries come in contact with water, immediately dry the battery with a clean towel.

   3. Keep LiPo batteries WELL out of reach of children.

   4. Always store your LiPo batteries in a safe and fireproof container away from flammable objects. A LiPo Sack or metal / ceramic storage container is best.

   5. Always store your LiPo batteries partially 50% charged, cell voltage between 3.8v to 3.9v. They will maintain their performance levels over time and there’s no need to cycle them unless stored for periods longer than 3-6 months.

Caring For Your LiPo Batteries:

   1. Charge LiPo batteries with good quality Lithium Polymer charger. A poor quality charger can be dangerous.

   2. Set voltage and current correctly (failure to do so can cause fire).

   3. Please check cell voltage after the first charge. Examples: 2-Cell: 8.4V (8.32 to 8.44) 3-Cell: 12.6V (12.48 to 12.66)

   4. Do not fully discharge your LiPo batteries. Discharging LiPo batteries beyond it’s critical minimum voltage (often 3.0v) can cause damage to the battery.

   5. Use caution to avoid puncture of the LiPo batteries. Puncture of cells may cause a fire.

Operating Temperature:

    * Charge:  0 to 45 degree Celsius

    * Discharge:  0 to 60 degree Celsius

Disposal Procedure:

   1. Batteries that lose 20% of their capacity must be removed from service and disposed of properly.

   2. Discharge the battery to 3V/Cell, making sure output wires are insulated, then wrap battery in a bag for disposal.

   3. Take LiPo batteries to a “Hazardous Waste Disposal” facility for disposal. LiPo batteries should always be taken to a “Hazardous Waste”

disposal facility for disposal.
