Battery Safety Information
Battery Using Instruction
Important information on the safe use of Lithium Polymer batteries. Read these instructions and warnings carefully to ensure the proper use of LiPo batteries.
1. Charge
1.1 First charge
Before using Lipo battery for first time, please fully charge the new battery with the specific Lipo balance-charger.
1.2 Charger
Charge lipo battery with specific Lipo balance-charger only. Other types of charger are not recommended.
1.3 Charging Current
Never charge Lipo batteries with current over the maximum charging current which was regulated by specifications (2–3C in general), strongly recommended should not exceed 5C. Higher setting may lead to charging insufficiency, inferior performance, heating and even leakage.
1.4 Charging Voltage
Charging Voltage should be controlled around 4.20V and under any condition should not beyond the regulated limit voltage (4.25V/cell). As for battery pack in series, please choose balance charging or charge each cell respectively. Series charging is not recommended. If the charging voltage is too high or you choose series charging, over-charge may occur. All these may result in battery swelling, heating or even leakage, severely deteriorating batteries’ performance and cycle life.
1.5 Charging Temperature
Batteries must be charged at a place within the temperature ranged from 15°C to 35°C or it may lead to the reduction of charging & discharging efficiency, charging insufficiency. Stop charging immediately if the battery surface temperature exceeds 50°C.
1.6 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.
1.7 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.
2. Usage
2.1 Checking Voltage
Please check the voltage of the battery 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, re-charging is advised. If the voltage difference of two cells is too huge beyond 100mV, 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.
2.2 Discharging Current
Never discharge batteries with current over the designed maximum continuous discharging current which was regulated in relevant specifications. Or the battery’s performance may be deteriorated and cycle life be shortened, causing overheating and even swelling, breakage, internal short-circuit, etc.
2.3 Discharging Temperature
Ensure the battery temperature during discharge remains within 65°C. 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.
2.4 Minimum voltage
Please make sure the cut-off voltage is not lower than 3.3V, otherwise the battery’s performance may be severely affected because of over-discharging.
3. Storage & Transportation
3.1 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.
3.2 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).
3.3 Storage Environment
Do store batteries at a place with low-humidity and free from corrosive gas within the temperature ranged from –20°C to +40°C.
4. Precautions and warnings
4.1 Crashing, hitting and bending batteries are prohibited. Protect them from sharp objects.
4.2 Under any circumstances disassembly of batteries is prohibited.
4.3 Do not throw batteries into fire, otherwise fire disaster or explosion may occur.
4.4 Do not soak batteries in liquid, such as fresh water, sea water and beverages (i.e. juice, coffee) etc.
4.5 The replacement of bare cells should be conducted by the supplier rather than the user.
4.6 The use of damaged batteries is prohibited. Batteries may be damaged by hitting during their transportation. If there are any abnormal features, such as damage of battery seal edge, breakage of hard case, or emitting electrolyte flavor, these batteries are not allowed to use again. Any battery with electrolyte leakage or emitting electrolyte flavor should be kept far away from flammable/combustible materials to avoid fire disaster.
4.7 If there’s any question while using, please contact relevant professionals for disposal.
4.8 Used or damaged batteries shouldn’t be discarded at random, but should be handed to specific Hazardous Waste Facility for disposal.
4.9 Don’t expose batteries under the sun; nor expose batteries in the stopped car.
