Question
I think I am doing something wrong when trying to charge my LiPo battery.

Hey.
I recently bought a rc plane, ST Model Discovery and I think I am having issues charging the batteries.
The plane came with a blue charge that looks exactly like this one:
http://www.singahobby.com/?q=node/18562
Now, on 3 places where written how to charge it there written completely different things on every place. (one is in the plane manual, one is in the charger manual, and one just on the charger itself) On the charger itself, which I consider most 'trusty' there written that if the green LED is off and the red LED is on, means its charging. On my case it's green LED on and Red LED flashing 1 time per second, that's why I think I am doing something wrond. But, in the charger manual there written, plug the charger to power source, Green LED is on, then plug the battery in, and red LED flashing and it charges. That's basically what happens to me, but I think they meant that the red LED only flashes once and then stays solid. And on the plane manual, written plug the charger to power source, red LED is on, and plug battery, green LED is on.

I am really confused and don't know what to do. I have 2 batteries and each of them were plugged for some good hours and none of them seems to be charged full, or partially (I have no way to check it though).
Am I doing something wrong? Thank you.

Without a voltmeter to check the charge of the batteries, hard to say what is happening. I'm guessing the packs may be over-discharged.


From the manual for the charger you referenced.
Connect 2S cellsl
to charger
LEDB&C red
(no flash)
2S battery charging
Connect 3S cells
to charger
LED B,C&D red
(no flash)
3S battery charging
fully charged
LED A green(flash),
B,C,D LED off
LED A green(flash)+LED B off:
1S battery charged full
LED A green(flash)+LED B&C off:
2Sbattery charged full
LED A green(flash)+LED B,C&D off:
3Sbattery charged full
During charging Relevant LED red
(flash)
Battery damaged
or not connect well

Are you doing something wrong? There is not much of a way for us to tell. You did not say if your battery was 2-cell or 3-cell, but at least the charger is supposed to handle either one. If you are going to stay in this hobby, you must have some way of checking your battery pack voltage. A cheap multi-meter is usually less than $10, or you can buy a checker like this: http://www.hobbyking.com/hobbyking/s...tery%20checker or this: http://www.hobbyking.com/hobbyking/s...rm_2S_8S_.html How will you ever know if your batteries charge unless you can measure it? Better chargers have a display that can show the voltage in each cell and total pack voltage. To help you out, we need to know the cell voltages before and after you tried to charge. Perhaps a better charger is in your future. Here is an economical one: http://www.hobbyking.com/hobbyking/s...earch=accucell

What discharge means?
It's the first time I'm charging those batteries, and basically the first time I am charging. I don't know much to say, it's a 3 cell battery.

How many mah are the batteries?

Does it say on the charger the amps it can charge at with a 3s pack?

Does the charger have a name/model #?

You really need to find someone with a volt meter.

In addition to the requirement for a voltmeter you should read and understand everything in this article.
https://sites.google.com/site/tjingu...arging-how-tos

Next you should scrap the charger and replace it with one that has a display that tells you voltages and current. An example:
Imax B6: http://www.ebay.com/itm/like/2318442...&ul_noapp=true
This is not a charger I would normally recommend but it is adequate.

Please include your country in your profile. That would keep me, and others, from mentioning something you cannot get.

Come on I just asked how to charge with this charger and how can I tell it's charging.
I need both of the batteries full for tomorrow and seems like it's not gonna happen

I understand your frustration, but the reality is that your charger is a piece of junk and there is just about no way anyone can troubleshoot your situation when all the indication is a couple of lights that don't appear to agree with the instructions you have.

And especially difficult if he doesn't answer questions.
