Description

A 5000mAh powerbank taillored for DIY applications

Here is rechargeable battery with massive capacity for your Raspberry Pi or Raspberry Pi B PLUS, Arduino projects or anything else running under 5V! This battery is intended to provide full power to an iPhone, mobile, tablet, etc. but we have noticed that it also does a great job when it comes to powering a miniature computer and/or microcontrollers.

Inside, there is a Lithium Polymer battery of 5200mAh, a charging circuit (you can charge it using the supplied USB cable) and two powerful converters capable of providing a total of 2 amps on the USB ports. It is a key element to support the load of a Raspberry since it consumes 700mA if there is nothing else connected to it. 

With such a battery, it must be possible to connect a 2.5" display (powered from the 5V pin Pi), a wireless keyboard/mouse and a Wifi key. Enough to make a nano computer completely portable!

The "survival" time of the battery depends on what you are going to connect to it. It can work for 5:30 with a Pi without accessories (without keyboard, without mouse, without connected screen) but with a Wifi key (kept active with a ping done every second to maintain the active network connection).

There are 3 LEDs indicating the level of discharge and the on/off button.

Technical details

  • Battery of 5200mAh Li-Polymer (Lithium Polymer, LiPoly for intimates).
  • Sealed! 
  • Overload protection, over-voltage, over-current and short-circuit.
  • 3-LED charge indicator that shows the charging status and the state of discharge of the battery. 
  • Start button + operation indicator (LED) 
    • Press the button 3 sec to turn on (LEDs light up)
    • Press the button 1 sec to turn off (LEDs light off)
  • Allows the use of the battery (with your phone or Raspberry) while the battery is charging. 
  • Output:
    • 5.1V DC (5.1v for balancing the voltage drop in the USB cable)
    • 2.1A max (for both ports... So if one port consumes 2A, the other will not be usable)
    • If the output reaches a peak at 3A then the battery goes into protection mode and turns off.  In this case, disconnect all devices before turning on the battery.
    • 2 USB output ports type A (like those of PCs) allows you to connect two devices to charge (eg: your phone and a Raspberry-Pi).
  • Input (recharge): 
    • 5V 500mA or 1000 mA
    • 1 micro USB port (not to be mistaken, charging cable included)
  • Suitable for most digital devices operating under 5V, Smart Phone, iPod, MP3, MP4, GPS, ... 
  • Also suitable for powering a Raspberry, Arduino (in 5V) and your 5V projects.
  • Operating temperature: 0-40°C
  • Weight: 150gr

Documentation

The recharge

If the 3 LEDs flash, it means that the charging source is not suitable!

This battery has an Intelligent Circuit to detect the power of charging. Connected to a computer, it will charge at 500mA (the maximum allowed on a USB port). 

On a 1000mA USB power supply (like the one we offer for Raspberry), the charge will be 1000mA.

The battery will refuse to charge if the charging voltage is below 5V or if the charging current is less than 500mA. 

Charging before first use: 

Fully charge your battery before using it the first time.

Charge time: 

If your battery is fully discharged, it will have to be recharged up to 5000mAh. On a standard PC USB port limited to 500mA, it will take 5000mAh/500mA = 10 hours of charging. 

If your battery is discharged at 50%, it will be necessary to recharge the 50% missing, is 50% of 5000mAh = 2500mAh. If you use a plug-in charger capable of supplying a 1000mA current, you will need 2500mAh/1000mA = 2.5 hours = 2 hours and 30 minutes of charging.   

Do not recharge this battery from a Raspberry Pi (see details below)

Recommendation on Lithium Ion/Lithium Polymer battery

This type of battery is extremely powerful and capable of storing huge energy. These exceptional characteristics are also accompanied by a disadvantage: warming up. 
To control this disadvantage, the battery is equipped with an intelligent energy manager.  

Nevertheless, if the battery is technically "abused", or if it is damaged physically or electrically, it can then heat up quite hard in case of high-speed charging/discharging. That's why these batteries use intelligent charge/discharge circuits... and short-circuit protection. Despite this protection, be careful not to create a short-circuit. 

It is recommended not to recharge a Lipo battery on clothing (cfr Flora range) or near potentially flammable material. Even if all the protections are taken by the different manufacturers, the latter always advise to recharge Lipo, Li-Ion batteries under surveillance. 

If the battery case is open or damaged, it is important to take special measures (inspection, re-packaging, stop using).

Here is a video showing what can happen to a Lipo battery when it is overloaded (in this video the destruction was the target result and the battery was thus "abused" to reach this end... it does not remain less interesting) 

The battery and Raspberry-Pi

This battery has been selected to power a Raspberry-Pi to turn your Pi into a portable project. 

Contrariwise, do not use your Raspberry to try to recharge this battery. The MAX current of a USB port of Raspberry is 140mA... while the battery requires 500mA minimum to recharge.

So do not try to recharge your battery from your Pi, you can damage your Pi.
