3000mAh to ensure a long-term supply for mobile projects
Lithium Ion Polymer batteries (also known as 'lipo' or 'lipoly') are fine, light and powerful. The output voltage is in the range of 4.2V when fully charged to 3.7V. This battery has a capacity of 3000mAh for a total of about 12 Wh
If you need a less powerful battery, there are also other models.
The battery is delivered with a 2-pin JST-PH connector (see picture) and has the necessary protective circuitry. Thanks to their real JST connector, not a compatible version, the connection/disconnection will be done smoothly and you are safe from cable tears, problems of correct connection, more or less suitable insertions.
The protective circuitry prevents battery voltage from climbing too high (over-charge) or too low (over-use/over-discharge) which means that the battery will shut off automatically when it is completely dead and reaches the voltage of 3.0V. It will also protect the battery against short-circuits. However, even with these protections it is very important to use ONLY a constant current/ constant voltage Lilon/LiPoly charger with a charging current of 1500mA or less. Example of LiIon/LiPoly charger with constant current/constant voltage
Like most LiPo's, this battery is not equipped with an integrated thermistor. This is why it is suggested to charge at max 1/2C (or even less). 1500mA is the maximum in this case. Even 500mA is correct since it is the maximum current you can get from a USB port
Additional safety note: Don't use a NiMH/NiCard/acid battery charger! Also, do not abuse this type of battery, do not short-circuit, twist, crush or break. As with all Lithium Ion Polymer batteries and any type of power source - they should be used by experienced people (experts) who are comfortable with power supplies.
For electronic application only
These batteries are designed for electronic project power and not for motor propulsion. The battery is equipped with a protection circuit that deactivates the battery if its voltage drops below 3V or if the current is too high.
The discharge current of this type of battery is 0.5C to 1C MAX!
For example: a 500mAh 1C battery could produce a current of 1x500mA = 500mA max
If you need to motorize a project, you have to look for modeling batteries able to deliver several C. Indeed, the starting of a motor creates a very important current draw (close to the current of short-circuit), therefore, a suitable battery is required.
Some modeling batteries are able to deliver up to 35C!
Example: a battery of 2500mAh 35C could produce a current 35x2500mA = 87500mA = 87.5A without flinching! What ensure the start of any type of motor.
Be careful however, these batteries have no protection and can catch fire if they are not used/charged/discharged correctly.
