Hey guys. I was looking at batteries and realise that i couldn't do that without your help. First of all, as i was looking in Amain, i found 2 Align batteries and didn'\t know what a thing is. Look at those 2:

http://www.amainhobbies.com/product_...oducts_id/9305

The only difference of those two is that in the name. The first says 22C and the other 16C. What is the difference. I read the note and can't undertsand.

Also, the note says that if i over-discharge or over-charge or whatever else, it may burst. I saw LiPOs bursting and is not a good show at all. So you guys, can you tell me what i must do with LiPOs? I don't have a clue. I never ALMOST involved with electric and is just too difficult to start without hve an idea.

The C value indicates how much current the battery can supply. Basically multiply the C value by the capacity to get the current.

A 22C 2100mAh battery can produce 22 * 2100 = 46200mA or 46.2A
A 16C 2100mAh battery can produce 16 * 2100 = 33600mA or 33.6A

You want the battery to be able to supply at least as much current as the ESC requires. If you're using a 35A or 40A ESC for example, you'll want the 22C battery over the 16C battery. If you're using a 30A or less ESC the 16C battery will work, 22C is more than you need but will work also.

To avoid overcharging a lipo, just use a good lipo charger and remove it when it's done charging (usually about 1 hour when charging at a 1C rate, which is recommended for most batteries). Most chargers will shut off automatically when full charged is reached but it's a good idea to not leave them unattended, don't leave them on the charger over night, don't leave the house while charging etc.

To avoid over-discharging, simply stop as soon as you start to notice the power dropping. Don't run it until the heli won't fly any more. Some people time a few flights to get an idea how long the battery will last then set a timer in the TX and land when the time is up.

Ok. So, if i use a 30C or less ESC with the 22C battery, it will burnt, right?

No, not at all ... it just means your battery will be able to supply more amperage than your ESC would need. Having a larger battery like a 22C gives you room to grow in the ESC/motor area.

But if the motor or something got more amperage than the ESC can handle, can the ESC burn? What you must do to burn the ESC?

The ESC controls what power the motor draws from the battery.

To burn an ESC your motor could go bad and burn the ESC, or other issues like a short in the wiring could burn the ESC but typically batteries unless they are crappy will not burn your ESC.

If you have a power hungry motor and large ESC with a less than adequate battery (opposite of what you asked) you could do damage, which you will notice by how warm the electrical components are.

Oh, just a moment. If i have a big strong motor and a big ESC but my battery is...for example a NiMH 650 mAh (that's a little, right?) could do damage? But how? If you have a small battery, the heli will just not hover at all.

Yeah, but ... the motor and ESC could put too much demand on the battery and cause it to overheat/toast.

In any event, I recommend batteries with at least 20c ... all of mine are 25c and I run a 3500kv motor with a 35A ESC.

Ok. Hey, do you have any quide for a noob in electrics? I mean something that can explain everything about batteries, ESC, BEC and that things.

I wish I did, I just picked up on things I have read from other threads and such. There may be something like that out there, oh and finless videos on Helifreak.com helped.

Start reading this and other forums and post questions as they form. You'll learn.

I started already.
