Difference Between Li-Pol Battery and Li-Ion Battery

Li Pol better than Li Ion but the cost to the vendor issued too expensive. so .. Which is it?

This is a question that often arises.. :)

It is true that in some article stated that Li-Ion ( Lithium Ion ) better than Ni-Cd ( Nickel Cadmium ) mainly because it is lighter, energy density and no memory effect.

Lithium is the lightest metal, there are some advantages and disadvantages of Li-Ion and Li Polymer :

#difference 1
Li Pol battery is more flexible and malleable as gel, and the manufacturer is not limited by standard cell shape. Instead Li Ion has limited form of construction, the battery should be shaped box. The possibility of choosing  Li Pol because of it is flexible and it can be thinner and lighter than Li Ion.

All About Battery Charging

Many theories , tutorials , tips and tricks on the internet that talk about mobile phone battery or mobile phone charge

Some people argue that the mobile phone battery must often be filled..
Some people also argue that cell phones should not be until the battery is empty..
There is also the opinion that if charge the phone battery must be in a state of empty battery ..
Which is correct?
We try to solve with.. :D
Most phones now use Lithium batteries
Lithium has 2 types, there are Li - Ion and Li - Polymer
Whereas the previous generation is Nickel

Open BTS

From SpeedyWiki

OpenBTS (Open Base Transceiver Station) is a software-based GSM base stations, allowing the phone to call without using a GSM network service provider. OpenBTS is known as the first open source implementation of the GSM industry standard protocols.

The estimated price is about Rp. 15-25 million/piece, well below the usual Cellular base stations are usually spend hundreds of millions or Billion dollars.


The main fear is usually not in the technology but rather in regulation (sad indeed).

so, for further information about OpenBTS please read or download the article here

OpenBTS (Open Base Transceiver Station) adalah sebuah BTS GSM berbasis software, yang memungkinkan handphone GSM untuk menelepon tanpa menggunakan jaringan operator selular. OpenBTS dikenal sebagai implementasi open source pertama dari protokol standard industri GSM.

Perkiraan harga sekitar Rp. 15-25 juta / buah, jauh di bawah BTS Selular biasa yang biasanya dalam orde ratusan juta hingga beberapa Milyard rupiah.

Ketakutan utama biasanya bukan di teknologi tapi justru di regulasi (menyedihkan memang).
