Default Honeybee King power supply - carbattery

I bought a Honeybee King II. I am newbe and need a lot of stick time to learn. Following Radd I am not going very far. The battery only lasts a few minutes and takes 3 hours to charge. So this is going to take for ever. I can't buy more batteries just yet.
Question 1: The directions say to charge for only 2 hours. Do I have to charge for 2 hours, unplug and let it sit, and then charge the last hour?
Question 2: If no, then can I leave it on the charger over night? In other words when the light changes from blinking charge to steady green is it still charging?
Question 3: The Lipo pack is 11.1 volts. Can I run the helicopter off of 12 volt car battery so I can get more stick time?

thanks
Lee

leea,

What charger are you using that it is taking 3 hours to charge your Lipo?

Also, to answer the question about the car battery, I assume you mean using a long extension to hook it to (since the battery is too heavy to be lifted by the heli)? An extension could cause (very likely, actually) the heli to tip to one side, inducing directional travel you would not want.

Also, DO NOT EVER leave a Lipo on a charger overnight. It should ALWAYS be charged with you attending to it. If you charge a Lipo incorrectly, it can explode, vent, or cause a fire which could burn your house down. If you do it while you are sleeping, well, it could end up killing you in the process.

I am using the charger that came with my Honeybee. It is an E sky balancer charger EK2-0851. It will do a 11.1V or a 7.4V pack. The output is .8 amps and the battery is a 1000mAh so in a perfect world at max input rate it would take 75 minutes but I assume the charge is not a consistent .8A but ramps down as the battery gets charged, or maybe the .8 only applies to the 7.4V packs.

I know the extension cord will induce movement, but I am not planning on moving very far anyway.

I suppose it you could secure it to the heli, the extension cord could work....

I just am not sure I like the idea......

Any heli experts wanna chime in here?

Not a heli expert, but it just does not seem like the best idea lol....

What happens when you get a little farther out on accident and you lose power and the cord rips off?

Marc,

I believe the "technical" term for that is MAYHEM.

Don't say I didn't warn ya.

My concern was having the cord cause it to tip, then you end up with an outta control heli attached to a 12V car battery......just sounds like a recipe for disaster if you ask me. But what do I know?

I understand the concern about the extension cord. I promise to live within its limits.
My real question is can I operate a 11.1V helicopter on 12V without hurting it?
Maybe I should move this to the batteries and chargers forum.

Yes, actually you likely dont operate your heli at 11.1v ever that often. A fully charger 3S has 12.6v. The volts drop as the amp draw is higher....

I saw a youtube video where a guy was learning how to fly a heli in his garage. He tethered it to the floor.

I still don’t know how he managed not to get hit by the heli.
Do a search on you tube I think it was called tethered heli.

It is not a good idea to attach anything to the helicopter.
Even putting a heavier battery ( 1800mah to 2200mah) can affect
the flying characteristics of a helicopter.

As soon as you take off it will need to take up the weight of the cable.
It is going to tilt your helicopter and make it take off in a direction.
Your helicopter will then turn into a man eating machine.

Try an FMA charger. It'll charge your batts in less than an hr. The Cellpro 4 S would work well. They sell adapters to fit the charge plug on the batts.

DO NOT USE A 12V CAR BATTERY!!!!! They have way to many amps for your little motor.It will cause serve damage and may even start your bird on fire. The charger that comes with the HBK is junk and a fire hazzard. I suggest you get a new Charger/Balancer as soon as you can. Also get a new battery I use the Mystery 2400 and get 20 min of fly time. My charger (a Cellpro 4s) will recharge that in about a half hour. Please dont take safety out of the pitcure because you are jonesing to fly...live today fly again tomorrow

Just because the battery can SUPPLY the amps does not mean the motor will DRAW the amps.

It;s high volts that will cook the motor not high amps on the same prop.

I have no need to, I already know what will happen...nothing. As long as the motor can handle 12v (which MOST can).

Lol...

I dont get it, NOTHING is going to burn up as long as it can handle the voltage. All it is is a BIG battery with a HUGE capacity.

Your ESC will not burn up as long as the motor is not drawing amps higher than its rating, your servos will not burn up because the BEC is supplying it with the correct voltage, your motor will not burn up because you have it set to draw the correct amps (and it can handle 12v).

A 3S1P lip has 12.6v fully charged and usually sags to 12.4-5 after it settles. And as the amp draw increases, the volts sag to compensate.

What is the problem here?
