Lipo battery charging & storage
• Always use a charger made to charge LiPo packs.
• Double check that the settings for the lithium polymer charger are correct for the pack being charged. This includes the cell count, as well as the current settings. In general, most lithium polymer batteries should be charged to no more than 4.2 volts per cell or depleted to less than 3.0 volts per cell.
• Ensure that charging leads are connected correctly. Reverse charging can lead to cell damage or a fire or explosion.
• Always charge LiPo batteries on surfaces that won’t catch on fire such as cement, steel, ceramic, or stone. Wooden tables and carpeted floors are not recommended charging surfaces.
• Do not charge batteries near flammable products or liquids.
• Never charge a LiPo battery while inside your model or other electronic devices. If it catches fire it can lead to total destruction of the item it is being charged in.
• LiPo batteries should be charged within a temperature range of 0C to 50C. Batteries charged outside this temperature range may experience leakage, heat generation, or cell damage.
• Never leave a charging lithium polymer battery pack unattended.
• If unsure of the charge rating, never charge a lithium-polymer battery pack at a rate over 1C (1 x the battery pack's rated capacity).
• Never charge a LiPo pack that has ballooned or swelled due to over / under charged or from a crash.
• Never charge a lithium-polymer battery pack that has been punctured or damaged in a crash.
• Never, under any circumstances let the positive and negative battery leads touch each other. It can lead to cell ballooning, cell damage or fire, or an explosion.
• Have a fire extinguisher near the charging area or a large bucket of dry sand. Do not try to extinguish with water.
• If you notice your LiPo battery pack is swelling, stop the charging process immediately, put the battery in a safe container , and observe it for 15 minutes.
• Always charge your Lipo battery packs in a Lipo charging safe bag.
• Keep LiPo battery packs out of reach of children.
• Do not put battery packs in pockets or bags where they can short circuit.
• Do not store or transport batteries where they can come into contact with sharp or metallic objects.
• Do not store your LiPo pack in extreme temperatures below 0C or above 50C.
• Always store your LiPo pack in a safe and non-flammable container away from flammable objects. A LiPo Sack or metal / ceramic storage container is best.
• The speed at which a LiPo battery ages during storage is based on both storage temperature and state of charge. For optimum battery life always store your LiPo’s partially charged at room temperature. This will maintain their performance levels over time and there’s no need to cycle them unless stored for periods longer than 3-6 months.
• Never store a RC LiPo in a hot car fully charged for an extended period of time, this will cause damage.
• When storing batteries for extended periods, store at a half charged state.
