Basic Lithium Polymer (Li-Po) Battery Handling

Li-Po Battery
I have been using Lithium Polymer a lot lately since I found new hobby, playing helicopter. They actually Lithium Hybrid Polymer, because if you open it, got a little liquid inside and they are not fully dry cell.

In the begining, a lot of my Li-Po battery expand like balloon. Quite frustrated. After looking here and there on the internet, I be able to extent my Li-Po battery life : ) . Knowledge is money... So, here I just want to share a few tips how to take care of your Li-Po battery. I hope it benefits you.


Basic Lithium Polimer (Li-Po) Battery Handling


1. Never overcharged a Li-Po Battery.
    Voltage when fully charge for 1 cell Li-Po is 4.2V, empty is 3.7V.
    If you have 2S Li-Po = 2 cell, empty is 7.4V (3.7Vx2), fully charged is 8.4V
    If you have 3S Li-Po = 3 cell, empty is 11.1V (3.7x3), fully charged is 12.6V
    Same calculation for 4S, 5S, and so on...

2. Avoid using battery until below 20% of its capacity. That is approximately 3.8V.

3. Do no store in hot enviroment. Store in shaded dry cool place.

4. Avoid store Li-Po battery fully charged.
    Store Li-Po in 50% charged if you not using them for more than 1-2 week

5. Stored Li-Po battery can discharged itself, make sure you check
    them at least once a week to avoid power drained below 3.7V

6. Do not punch hole to Li-Po battery.

7.
Never charging untended. Put battery on fire proof material away
    from other easy to burn material. Better using Li-Po Guard Bag.

8. Avoid drop a Li-Po battery on hard surface.

9. If you want to throw a way ballooned/damaged Li-Po, fully drain its
    power by hook-up to light bulb and wait until light go off and throw away.

That all that I think important to take care of your Li-Po batteries. If you think I miss out somehing, fell free to comment below. Thank you for visiting my blog : )

Hi all,
Entering oil and gas business recently make me wonder why they call platform name with end A, B, C. They actually Alpha, Bravo, Charlie... and certain area that have 1 mother platform and 4 satellite platform, they add A, B, C, D, and E after each platform name. The mother platform, xxxxx Alpha. The satellite platform, xxxxx Bravo, xxxxx Charlie, xxxxx Delta, and xxxxx Echo.

I c, so what are the rest? So I try ask uncle google for it and found they actually NATO spelling alphabet.. lolcats! This exist because of radio conversation can be fuzzy and hard to hear each other especially on busy radio channel.

The Morse Code Table

What Morse Code?
I watched a movie a few days ago and saw people using Morse code in that movie. Tu..tuuut.tuut.bla~bla~bla~... and the guy just said the translated massage on the spot. Wow, wtf!.

I heard about Morse code many times before that, but never really bother to know more about it. Well, we are not really using that Morse code in our hand phone, pda, text message isn’t.

But now, I'm just curious about it. So here, I want to share with my blog visitor about this Morse code and this is also for my future reference. ^.^". Inside the table below are the alphabet and its Morse code.

Table below are for numbers;

1.----
2..---
3...--
4....-
5.....
6-....
7--...
8---..
9----.


Inside the table above is just to visualize the Morse Code. The truth to learn Morse Code is to remember it sounds. Below link are the Morse code sounds from A to Z. Each alphabet separated by 5 second silent.


You can hear it while looking at table above. The dot (.) represent short "beep" sound and the dash (-) represent the longer "beep" sound.

That's all I know for now. Of course there is a lot more Morse code such as code for pro-sign, punctuation mark and so on. Above is just the basic part of Morse code. hehe. Thank you for visiting my blog. <(^.^)/
