How to use FPV lipo battery safely? Following is somethings you need to pay attention.
- First charge. Before using lipo battery for first time, please fully charge the new battery with the specific lipo balance charger for it.
- Charger. Charge lipo battery with specific Lipo balance charger only, other types of charger are not recommended.
- Charging Current. Battery charging current must never exceed the manufacturer's specified maximum which was regulated by specifications. Higher setting may lead to charging insufficiency, inferior in performance, heating and even leakage.
- Charging Voltage. Charge lipo battery at no more than 4.20V per cell (4.25V is the maximum cell charge voltage). As for battery pack in series, please choose balance charging or charge each cell respectively.Series charging is not recommended.
- Charging Temperature. lipo batteries must be charged at a place within the temperature ranged from 15℃to 35℃ or it may lead to the reduction of charging & discharging efficiency, charging insufficiency. Stop charging immediately if the battery surface temperature exceeds 50°C (120°F).
- Reverse charging is prohibited. Please correctly connect the positive (+) and negative (-) electrode of the battery, and strictly avoid reverse charging. Reverse charging will destroy the battery cells and may reduce the charging& discharging performance and security of the battery, even result in heating or leakage.
- Abnormal charging. If there’s any abnormal condition occurs during the charging process, please discontinue the charging process immediately and consult relevant professionals for disposal.
- Checking Voltage. Please check the voltage of the pack before using. The voltage difference between any two cells should not be too huge, if within 30mV, no need to charge. If between 30mV-100mV, recharging is advised. If the voltage difference of two cells is too huge beyond 100mV, recharging is required before usages. Due to the one with lower voltage may happen to over discharge while using, causing battery swelling, heating, and finally deteriorating the performance and shortening the cycle life.
- Discharging Current. Always observe the maximum discharge current of the designed maximum continuous discharging current which was regulated in relevant specifications, or it can become very hot and swell, and will be deteriorated and cycle life be shortened, causing breakage, internal short-circuit, etc.
- Discharging Temperature. Ensure the battery temperature during discharge remains within 65℃, if higher, the battery should be suspended using until it cools down to ambient temperature naturally. Higher temperature may result in battery swelling and performance deterioration.
- Minimum voltage. Please make sure the cut-off voltage is not lower than 3.0V, and we highly recommend not lower than 3.3V, otherwise the battery's performance may be severely affected because of over-discharging.
3. Storage & Transportation
- Transportation. Please avoid severely vibration, shocks, extrusions and high temperature during batteries' transportation, and please do take care while carrying them. All batteries should be packed by soft materials for protection.
- Long-term storage. If storing for a long time, batteries must be stored at about 3.8V/cell (approximately 50% charged)/ in the semi-electric status (about 3.8V). Do regularly charge & discharge them for maintenance (about 1-3 times every 3 months).
- Storage Environment. Do store lipo batteries at a place with low-humidity and free from corrosive gas within the temperature ranged from -20℃to +40℃.
4.Precautions and warnings.
- Crashing, hitting, bending and short-circuit batteries are prohibited.
- Under any circumstances dis-assembly of batteries is prohibited.
- Do not throw lipo batteries into fire or soak batteries in any liquid. - Do not store lipo in a car or other container which may get hot.
- Always land your model when the power starts to reduce.
- The replacement of bare cells should be conducted by the supplier rather than the user.
- Used or damaged batteries shouldn’t be discarded at random, but should be handed to specific Hazardous Waste Facility for disposal.
- Store lipo batteries in a part charged state and out of children.
