Lithium Ion batteries though have high energy density and light in weight, are very dangerous if abused i.e. if you overcharge or undercharge the battery or draw more current than it can provide then it can explode damaging the surrounding or even potentially harm the humans around. To prevent this from happening you should use your batteries with a protection board.

This 4S 40A Lithium-ion Battery Protection Board monitor protects three cells connected in series by monitoring the voltage and current in and out of the battery pack and if any unsafe condition happens then it will cut off the battery from the load or the charger. This can be used in any DIY project where the current is low like Arduino or Raspberry Pi based projects, 3D printers, Quadcopters, Robotics applications etc. As it can handle current up to 40A you can also use it in slightly higher currents. This Board is suitable for 18650 cells having nominal voltage of 3.6V or 3.7V, so it can provide a nominal voltage of about 14V and maximum voltage of 16.8V.

The CH340 Soldered Nano Board R3 Chip without USB Cable chipboard is based on the famous Arduino platform and does all the functions of Uno, but with a smaller footprint.
Nano CH340 Soldered Board R3 Chip without USB cable is vital for your small project where you don’t need much of a pin-outs but the small size is very important to make it look good.
The Nano equips a low-cost USB-Serial Chip that makes it less in price than Nano with FTDI USB-Serial Chip used on older versions of Arduino Nano.
The Nano is a small, complete, and breadboard-friendly board based on the ATmega328 (Arduino Nano R3). It has more or less the same functionality of the Arduino Uno but in a different package. It lacks only a DC power jack and works with a Mini-B USB cable instead of a standard one.
The Nano can be power via the mini-USB connection, 6-20V unregulated external power supply (pin 30), or 5V regulated external power supply (pin 27). The power source is automatically selected to the highest voltage source.
The size of Nano V3.0 with CH340 Chip is only 43 mm x 18 mm; it comes with 6 PWM I/O from the total of 14 digitals I/O, 8 analog inputs, 16Mhz clock speed and 32kB of flash memory
