5 tips Looking After Quadcoper Lipo Battery for You

Some people maybe can fly quadcoper but do not know how to looking after quadcoper lipo battery. As we know lipo battery provide quadcopter with energy, is very important for quadcoper system. But lipo battery is very dangerous you will be at risk if operating conditions than those described as below. The following suggestions will help you a lot.

Tip 1: Charging quadcoper lipo battery

Charging current

Charging current should be less than maximum charge current specified in the Product Specification. Charging with higher current than recommended value may cause damage to cell electrical, mechanical and safety performance and could lead to heat generation or leakage.

Charging voltage

Charging shall be done by voltage less than that specified in the Product Specification (4.2V/cell). Charging beyond 4.25V , which is the absolute maximum voltage, must be strictly prohibited. The charger shall be designed to comply with this condition.

It is very dangerous that charging with higher voltage than maximum voltage may cause damage to the cell electrical, mechanical safety performance and could lead to heat generation or leakage.

Charging temperature

The cell shall be charged within 0 °C ~40 °C range in the Product Specification

Prohibition of reverse charging

Reverse charging is prohibited. The cell shall be connected correctly. The polarity has to be confirmed before wiring, In case of the cell is connected improperly, the cell cannot be charged. Simultaneously, the reverse charging may cause damaging to the cell which may lead to degradation of cell performance and damage the cell safety, and could cause heat generation or leakage.

Tip 2:Discharging quadcoper lipo battery

Discharging current

The cell shall be discharged at less than the maximum discharge current specified in the Product Specification. High discharging current may reduce the discharging capacity significantly or cause over-heat.

Discharging temperature

The cell shall be discharged within -20 °C ~60 °C range specified in the Product Specification.


It should be noted that the cell would be at over-discharged state by its self-discharge characteristics in case the cell is not used for long time. In order to prevent over- discharging, the cell shall be charged periodically to maintain between 3.6V and 3.9V.

Over-discharging may causes loss of cell performance , characteristics, or quadcoper lipo battery functions.

The charger shall be equipped with a device to prevent further discharging exceeding a cut-off voyage specified in the Product Specification. Also the charger shall be equipped with a device to control the recharging procedures as follows:

The cell battery pack shall start with a low current ( 0.01C) for 15-30 minutes, i.e. -charging, before rapid charging starts. The rapid charging shall be started after the (individual) cell voltage has been reached above 3V within 15-30 minutes that can be determined with the use of an appropriate timer for pre- charging. In case the (individual) cell voltage does not rise to 3V within the pre-charging time, then the charger shall have functions to stop further charging and display the cell/pack is at abnormal state.

Tip 3:Storage lipo battery

The cell shall be storied within -10 °C ~45 °C range environmental condition.

If the cell has to be storied for a long time (Over 3 months),the environmental condition should be:

Temperature: 23 ± 5 °C

Humidity: 65 ± 20%RH

The voltage for a long time storage shall be 3.6V~3.9V range

Tip 4:Handling of Cells

Since the quadcoper lipo battery is packed in soft package, to ensure its better performance, it ’ s very important to carefully handle the battery

Soft Aluminum foil

The soft aluminum packing foil is very easily damaged by sharp edge parts such as Ni-tabs, pins and needles.

  • Don’t strike battery with any sharp edge parts
  • Trim your nail or wear glove before taking battery
  • Clean worktable to make sure no any sharp particle

Folding edge

The folding edge is form in quadcoper lipo battery process and passed all hermetic test Don’t open or deform folding edge.

Mechanical shock

Don’t Fall, hit, bend quadcoper lipo battery body

Tip 5:Others Prevention lipo battery

Prevention of short circuit within a battery pack

Enough insulation layers between wiring and the cells shall be used to maintain extra safety protection.

Prohibition of disassembly

  • Never disassemble the cells The disassembling may generate internal short circuit in the cell, which may cause gassing, firing, or other problems
  • Electrolyte is harmful LIPO battery should not have liquid from electrolyte flowing, but in case the electrolyte come into contact with the skin, or eyes, physicians shall flush the electrolyte immediately with fresh water and medical advice is to be sought.

Prohibition of dumping of cells into fire

Never incinerate nor dispose the cells in fire. These may cause firing of the cells, which is very dangerous and is prohibited.

Prohibition of cells immersion into liquid such as water

The cells shall never be soaked with liquids such as water, seawater drinks such as soft drinks, juices coffee or others.

Battery cells replacement

The quadcoper lipo battery replacement shall be done only by either cells supplier or device supplier and never be done by the user.

Prohibition of use of damaged cells

The cells might be damaged during shipping by shock. If any abnormal features of the cells are found such as damages in a plastic envelop of the cell, deformation of the cell package, smelling of electrolyte, electrolyte leakage and others, the cells shall never be used any more. The cells with a smell of the electrolyte or a leakage shall be placed away from fire to avoid firing.

All of tips is base of looking after quadcoper lipo battery, these tips are form some experienced pilots and lipo brands(Gens ace , Hobbyking, Maxamp) which are great help to you. If you have some questions please leave your comments.
