Since the pouch cell has no strong metal casing, by themselves they are over 20% lighter than equivalent cylindrical cells. The advantages of Li-ion polymer over the lithium-ion design include potentially lower cost of manufacturing, adaptability to a wide variety of packaging shapes and reliability. Its main features and highlights are as follows:

1. High Energy Density:
the weight of a Lipo battery is approximately one half compared to a nickel-cadmium or nickel-metal hydride battery of similar capacity. Moreover, the volume of the Lipo battery is 40% to 50% smaller than that of a nickel-cadmium and 20% to 30% smaller than that of a nickel-metal hydride battery.
2. Higher Cost-to-Energy Ratio:
in comparison to all other kinds of rechargeable battery categories, the capacity and density of Lipo battery is generally higher than the same category liquid type lithium battery.
3. High Discharge Rate:
Honcell provides Lipo cells and packs from 0.2C to 45C highly discharge rate batteries for vast applications where need power.
4. Long Cycle Life:
under normal operating conditions, the Lipo battery still remains 60%-80% of the original capacity after 500 charge/discharge cycles.
5. No Memory Effect and Reconditioning Need:
Lipo battery is free from the so-called memory effect, a phenomenon seen in nickel-cadmium in which the apparent battery capacity decreases when shallow charge and discharge cycles are repeated.
6. Highly Flexible Dimension and Low Profile:
T x W x L (T: thickness W: width L: length) from 1mm to 12mm thick, 10-90mm wide, and 13-180mm long. Batteries resembling the profile of a quarter credit card are feasible.
7. Flexible Form Factor:
cells are not bound by standard cell formats. With high volume, any reasonable size can be produced economically.
8. High Voltage:
a single Lipo cell has a voltage of a mean value 3.7V, which is equal to either three nickel-cadmium or nickel-metal hydride cells connected in series.
9. Wide Capacity Range:
single cell from 35mAh to 10Ah in only a 0.12mm thick aluminum laminate film outer covering.
10. Light Weighted:
The use of aluminum laminate film for packaging provides light-weight advantage in comparison with other rechargeable categories.
11. Small Impedance:
equal to or more than 25mΩ
12. Wide Range Operating Temperature Conditions:
from -20℃ to +80℃
13. Improved Safety Performance::
as the aluminum laminate film outer package is different from the meta shell of liquid lithium ion battery, and once safety problems arise, there is no explosion but only expansion.
14. Pollution-free:
Lipo battery does not contain any polluting substances such as cadmium, lead, mercury, etc.
15. Non-metal Lithium:
Lipo battery does not employ any lithium metal. It is not governed by aircraft transportation rules relating to carrying lithium batteries in passenger airplanes.
16. Fast Charge Capacity:
LiPo batteries must be charged carefully. The basic procedure is to begin at constant current until each cell reaches 4.2 V. The charger must then switch to a constant voltage mode, and the charging current will gradually be reduced as the charger holds the cell voltage at 4.2 V. This continues until the charge current has dropped to a small fraction of the initial charge rate, at which point the battery is considered fully charged.
17. Battery Protection Circuit Module (PCM) Available:
Capable to modify with protection circuit to ensure excellent safety level.
18. Battery Pack Assembly Available:
Whatsoever in an hard case envelope or PCM, fly leads, and/or with the genuine wire connector in either series or parallel strings connection.

The purpose of a battery pack is to provide convenient integrated more powerful source. LiPo batteries are usually composed of several identical HJL secondary cells in parallel and series. By adding more cells in a series chain, this does not increase the Amp Hour capacity of the battery , but it increases the Watt-hour capacity, or the total stored energy, in proportion to the number of cells in the chain. The capacity can be increased through adding more parallel cells, this increases the Amp Hour capacity as well as the Watt-hour capacity without increasing the battery voltage. Mostly, the configurations for such pack chains are 2S1P, 2S2P, 3S1P, 3S2P, 4S1P, 4S2P...

The Lipo batteries can come pre-attached with a genuine x-pin(x=2 or 3 or 4) connector in lead wires drawn out from the included necessary protection circuit module ( PCM ), as shown in previous demo. Because they have a genuine connector, not a knock-off, the cable won't snag or get stuck in a matching JST jack, they click in and out very smoothly. The included protection circuitry keeps the battery voltage from going too high (over-charging) or low (over-discharge) which means that the battery will cut off when completely dead at 3.0V or 2.75V on the basis of pre-selected type of PCM. It will also protect against output shorts. However, even with this protection it is very important that you only use a charger specifically designed for lithium ion polymer batteries in CC( constant-current) / CV (constant-voltage) to recharge them and at a C rate specified by HJL. Like most Lipo batteries.

The packs we are making have no NTC thermistor built in. This is why we suggest charging at lower current. We can definitely say charging at 0.2C is always a good rate, and available from any USB port if using a USB-powered charger. If your application requires a removable or replaceable battery, we are good enough to manufacture the complete product including battery and hard plastic case as a whole "hard case battery.

Preface

This document of "Handling Precautions and Guideline for Li-po Rechargeable Batteries" shall be applied to the battery cells supplied by HJL.
Note Ⅰ:
The customer is requested to contact HJL in advance, if and when the customer needs other applications or operating conditions than those described in this document. Additional experimentation may be required to verify performance and safety under such conditions.
Note Ⅱ:
HJL will take no responsibilities for any accidents when the cell is used under other conditions than those described in this document.
Note Ⅲ:
HJL will inform, in a written form, the customer of improvement(s) regarding proper use and handling of the cell, if it is deemed necessary.

1. Charging
Always use a charger specifically designed for Lithium ion polymer batteries, but never use other types of chargers to charge Li-po batteries. Failure to do so will damage the batteries and may cause fire and personal injury.
1.1 Charging Current:
Charging current should be less than maximum charge current specified in this specification sheet. 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.
1.2 Charging Voltage:
Charging shall be done by voltage less than that specified in this specification sheet (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 specified may cause damage to
the cell electrical, mechanical safety performances and could lead to heat generation or leakage.
1.3 Charging Temperature:
The cell shall be charged within 0 ºc ~45 ºc ranging in this specification sheet.
1.4 Prohibition of Reverse Charging:
Reverse charging is prohibited. The cell must 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
damages to the cell which may lead to degradation of cell performances and damage the cell safety, and could cause
heat generation or leakage.

2. Discharging
2.1 Discharging current
The cell shall be discharged at less than the maximum discharge current specified in this specification sheet. High
discharging current may reduce the discharging capacity significantly or cause over-heat. If you plan to discharge
battery at a higher current than the max current allowed, please consult HJL for other recommended solutions.
2.2 Discharging temperature
The cell shall be discharged within -10 ºc ~60 ºc range specified in this specification sheet.
2.3 Over-discharging
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. Over-discharging may cause loss of cell performances, characteristics or battery functions. In order to prevent the cell over-discharging, the cell shall be charged periodically to maintain between 3.6V and 3.9V. The charger shall be equipped with a device to prevent further discharging exceeding a cut-off voltage specified in this specification sheet. Also the charger shall be equipped with a device to control the recharging procedures as follows: a: The cell or battery pack shall start with a low current (0.01C) for 15-30 minutes, i.e.-charging, before rapid charging starts.
b:The rapid charging shall be started after the (individual) cell voltage has been reached above 3V within 15-30 minutes.
Do not place batteries near heating sources, nor exposed to direct sunlight for long periods. Elevated temperatures can result in reduced battery service life.
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.

3. Protection Circuit Module(PCM)
The cell or battery pack shall be protected by PCM and have the functions of over charge, over discharge and over current prevention to maintain safety and prevent significant deterioration of cell performances
3.1 Overcharging Prohibition:
Overcharging prevention function shall stop charging if any one of the cells of the battery pack reaches 4.25V.
3.2 Over-discharge Prohibition:
Over-discharging prevention function shall work to avoid further drop in cell voltage of 2.75V or less per cell in any cell of the battery pack. It is recommended that the dissipation current of PCM shall be minimized to 0.5uA or less with the over-discharge prevention. The protection function shall monitor each bank of the battery pack and control the current all the time.

4. Storage
Keep the cells in half-charged state to help keep them fully charged or completely discharged. Put the cells in cool and dry place when storing them. The cell shall be storied within -10ºc to 35ºc environmental condition. If the cell has to be storied for a long time unused (over 3 months), need to activate the battery once every 3 months according to the following steps:
1) charge at 0.2C to 4.2V then rest 5 min.
2) discharge at 0.2C to 2.75V then rest 5 min.
3) then charge again at 0.2C to 3.9V
The voltage for a long time storage shall be 3.6V to 3.9V range. The environmental condition is preferred at ambient temperature 20 ºc±5 ºc and relative humidity 65±20%.

5. Handling of Cells
