- LiPo (Lithium Polymer) batteries do not have any memory effect. Therefore, never fully discharge LiPo batteries as it will permanently damage the batteries.
- Do not store the batteries fully charged. It will lead to a shorter life span of the battery. Use the BMS Battery Storage Mode (see BMS Menu option 2, Storage Mode) for longterm storing (> 2 days).
- Lithium Polymer batteries are volatile. Failure to read and follow the below instructions may result in fire, personal injury, and damage to property, if charged or used improperly.
- Always keep a Class D (ABC-Powder) fire extinguisher near your battery charging/discharging and storage area. The battery charging/discharging and storage area should be free from any materials which can catch fire such as: wood tables, carpet, or gasoline containers. The ideal surface for charging and storing LiPo batteries is metal, concrete or ceramic.
- By purchasing this battery, the customer assumes all risks associated with lithium batteries. If you do not agree with these conditions, return the battery immediately before use.
General Guidelines and Warnings:
- It is crucial that all cells in a LiPo battery maintain the same voltage across all cells at all times.
- Never charge batteries unattended. When charging LiPo batteries you should always remain nearby to monitor the charging process, and react to potential problems that may occur.
- Never continue to charge LiPo batteries if the battery LEDs fail to recognize full charge.
- Overheating of the LiPo cells is an indication of a problem. The battery should be disconnected from the power supply immediately and placed in a fireproof location.
- Since delayed chemical reaction can occur, it is best to monitor the battery as a safety precaution. Battery monitoring should occur in a safe area outside of any building or vehicle, and away from any combustible material. Always charge LiPo batteries in a fireproof location.
- A battery can still ignite even after a longer period time.
- In the event of a crash, you must remove the battery for observation and place it in a safe open area away from any combustible material for an appropriate period of time.
- Never store or charge a battery inside of your car in extreme temperatures, since extreme temperature could cause a fire.
- Before charging make a visual inspection of the battery. Look for any damaged connectors, or other irregularities. Do not use it if you find any of the above issues with your battery.
- If any damage to the battery is found, or the voltage is significantly less for your battery than what is specified below, do not attempt to charge or use the battery; contact your supplier.
- It may happen that you witness a battery starting to balloon or swell up. This may lead to a deformed housing so that it does not fit into the battery compartment of the UAV anymore. If, at any time, you notice such a deformation, do not start charging this battery. If already started, discontinue the charging process immediately. Disconnect the battery and observe it in a safe place for an appropriate period of time. Continuing to charge a battery that has begun to swell will result in fire. Never use a battery if you find it swollen or ballooned.
- Never charge batteries unattended.
- Charge in an isolated area, away from other flammable materials. Use deliverable LiPo-safe bags or a non-flammable case for charging.
- Let the battery cool down to ambient temperature before charging.
- Do not discharge a battery to a level below 3.5 V per cell. Deep discharging a battery cell below 3.5 V can reduce battery performance or even destroy them.
Storage & transportation:
Preparing for storage: Storing a fully charged battery has negative effects on its life span. Thus, the battery comes in a mode, where it slowly unloads itself to a healthy storage-voltage using internal circuitry.
- Whenever possible store the batteries in the Storage Mode (see BMS Menu option 2) and only charge them completely, shortly before the next flight.
- For transporting and storing the batteries use LiPo-safe bags or cases.
- Store batteries at room temperature between 5°C and 25°C (41°F and 77°F) for best results.
- Do not expose batteries to direct sunlight (heat) for extended periods.
- Never leave the LiPo batteries on a full charge for more than 2 - 3 days. For longer intermissions you need to activate the Battery Storage Mode for safe storage until you are ready to use the battery again. Recharge the batteries right before the next mission.
Caring for batteries:
- Please check the battery voltage after charging. It is shown on the Main Screen of Status display and by the LEDs of the battery.
- The voltage for a 4-cell battery should fall e.g. between 16.4 V – 16.8 V
- Do not discharge batteries to a level below 14 V under load. Deep discharge below 14 V will deteriorate the battery performance.
- Never puncture the battery cells. Punctured cells may cause fire.
- Charge temperature Recommended: 10°C - 30°C (50°F - 86°F), Max.: 5°-40°C (41°F - 104°F)
- Discharge temperature: -10°C – 40°C (14 - 104°F)
- Storage temperature: 5°C – 25°C (41°F and 77°F)
Batteries that lost 20% of their capacity (BMS Menu option 5, battery status) must be removed from service and disposed of properly.
