Do you want to build your own power bank from your spare 18650 battery cells?  Then this 18650 5V 1A/2A Lithium Battery Digital Display Charging Module is for you. Just like a modern power bank the module is equipped with Dual USB output to charge the gadgets at 2.1A and 1A. To charge the batteries, this module has two USB inputs one is C-type input, and the other is a MicroUSB input. Onboard, a brilliant blue-colored illuminating LED Display displays the real-time battery percentage in the 0–100% range, as well as the IN and OUT Signal. Furthermore, the board contains a connection for installing an LED to be used as a flashlight, which is generally found on a POWER BANK.

So, if you have any spare 18650 batteries cells in your scrap box, buy this module and create your own Power Bank, then share your DIY experience with us.

This Lipo Low Voltage Alarm can be used to get the voltage from a lipo battery. It connects to the lipo battery's balance plug and outputs the voltage of the induvidual cells and the total voltage of the battery pack. It also has an onboard alarm that beeps when the battery voltage gets low. Use this alarm to stop draining the lipo battery completely and this increases battery life and preserves the battery performance.

The alarm is small and light specifically designed for use in quadcopters and mulitrotors. A loud alarm will sound with flashing LED if the voltage on any of the individual cell drops below the adjustable threshold. 

We highly recommend using a LiPo Low Voltage Alarm all the time while using a Lithium Polymer Battery. Since if the voltage of any of the cells of a Lithium Polymer Battery drops below 3 volts, then that particular cell can be permanently damaged.
