Turnigy 2200mAh 3S 40C Lipo Pack

what do expect people will leave one of the best lipo alone ?? just buy them right the way when HK email to you that it is just restock

 wesix 92 points

on the back of the lipo, there's a sticker with small writing. it should say how many C to charge it. C is the capacity of the battery. so a charge rate of 2C means 2 times the capacity. so a 2.2 ah battery like this one with a 2C charge rate, then a maximum of 2x2.2=4.4 Amp charge rate. ofcourse this is the safest high charge you can charge this battery with. going lower is better. usually, all lipo batteries support a charge rate of 1C. some high performance batteries like the Turnigy nano-tech support a 5C charge rate (ideally, full charge in only 1 minutes (60 mins/ 5 C charge rate=12 mins)

 wesix 92 points

sorry, i mean ideally, a full charge will be in 12 minutes

I think HK SS series 35-40A ESC comes with bare wire so you will need something like this (XT60 Female w/ 12AWG Silicon Wire 10cm (5pcs/bag) PRODUCT ID: 601B-12-10cm) or just the XT60 part and solder it to your ESC, the ESC wire that has a servo connector at the end connects to your KK board to power it.

 Roger 2257 points

What KK board you have? is it the KK2 or the old ones without the LCD. And what ESC do you have specifically (if OPTO or with BEC)? If you don't know any of that, you should read/learn more about basic RC circuits and components. The BSC output from the ESC will power the KK board. Here's one video about basic RC components but it doesn't show how to connect to a KK board.

 Roger 2257 points

You will have to get an ESC for brushless motor, the 3 wire end (bigger) goes to the motor, the 3wire signal wire (smaller) goes to the KK2, the remaining red and black wire of the ESC goes to the discharge plug of the lipo.

depends on the voltage you need .. the 3s work at 11.1 volts the 2s to 7.4 ... then only if you have a motor you can go to 20c 2200 mah mind 'you can climb as high as 3000, but most of last weigh more

 slashman347 24 points

ehm , it is happend what ESC you use ? is your ESC working power 2-3S or 2-4S ?
if you use an 3s , and in the RTF package is a Lipo of 2s = 7,4V power than your motor and ESC worked at the maximum, it goes very hot. other whise you change your config.

 wesix 92 points

you should really follow the specs on the battery. if its a 500mah battery for example, charging it at 5 amps mean you're using a 10C charge rate. which is not supported on any lipo i know of. and anyway, high charge rates tend to shorten lipo life significantly and decrease their capacity

 Jonathan 6 points

maybe one needs to be balanced?

 psguardian 33 points

I would agree with Jonathan, put them on a balance charge * 2a & if your charger will display per cell voltage set it to do so & watch from 4.18 -> full 4.2... One cell is likely not hanging at 4.18v or 4.19v.

 Jonathan 6 points

i did this recently with an older battery, and it took 9 hours to finally balance, it was only allowing it to go at .01 amps, because one cell was so far off from the others.

 Edimar 6 points

I will try charge my in 01 amp lets see thanks

 wesix 92 points

xt60 plug is around 17mm by 7mm

 Mark 4 points

Yes, you can. I´*m about to order some more :D

 Alessandro 8 points

I normally load these batteries at 5 amps ... and do not give problems ... to limit the temperature-controlled heat remove some current

Aller à* rcsearch.info beaucoup de choisir à* partir de là*.

 Roger 2257 points

It is normal. Your battery was not all empty when you began charging.

 Roger 2257 points

Sure, SK2830 takes 2S-3S lipo and turnigy plush 25A takes 2S-4S lipo so no problem there. I have several of these for my tri but with dt650 motors. Lots of power when needed.

 Captis 13 points

Yes sure can...i've been using it, there is no problem until now...

 John D. 30 points

What do you mean "until now..."?

 wesix 92 points

thats depends.. sk2830 can suck up to 20 Amps per motor. 4x20=80 amps this battery gives a maximum of 2.2 amps x 40c=88 amps this is pretty tight. but it will work. be sure to check battery and esc temperature after each flight. if the battery is warm, you'll need to either increase battery capacity or buy same size higher discharge batteries.

Hitec X4 is a great charger

 sl0flyer 49 points

Completely random.. and also incorrect. 3.7v is the nominal voltage. Don't go under 3.2, however ducking down to 3.0 temporarily shouldn't hurt the battery too much since that is the minimum voltage for LiPO's

 joseph lr 14 points

yes you can use this through ESC to power up your board

 whiskey29 72 points

Of course you can use any battery to power anything. But you have to make sure that the voltage is correct. This lipo is 11.1 and your board is 5v, you will need a Ubec for that. If your board has very little power consumption (not driving any servo), a 3A ubec is more than enough. Check this out SKU: TR-UBEC If that is the case, then you might want to use smaller C lipo and may be only 2 cell. It will be a lot lighter.

 joseph lr 14 points

yes you can use for both charging and discharging, and the smaller plug is for balance charge

 whiskey29 72 points

The Smaller plug is JST-XH I believe. The smaller plug is the balancing plug. all 4 cables represent each single cell. Black being Ground. Black and Yellow is the first cell, Yellow-Blue is second cell, and Blue-Red is third cell. If you measure each line as I explained above, you will get V of individual cell, if you measure Black and Red, you will get the total V of all cell.

 Nate5583 55 points

I believe that the wire coming out of the battery is 10 AWG there is no point in using anything bigger than that, but you may want smaller if your trying to save on weight if you're not pulling the full 88 amps

 jhova1717 161 points

It's 12 awg actually coming from battery

 Gary 2985 points

Should be ok,your motors max draw is 18amps,this x 4 means 72amps,the battery is good for 88amps.

 quadbrains 81 points

i am also using the same it is working nice with 7 min flight time

 Brandon 1 points

I ended up finding what I was looking for. Thanks. I wish I had known this ahead of time

 MTA-4 87 points

I'm not a big fan of adapters as they are just another connection that could cause problems. Personally I would just change the plug on the battery to suit your application.

 chi 1 points

u can get an adaptor thru hobbyking global, u need a xt60male - ec3 female plug adaptor. which i also bought at the same time when i bought this battery. next time u purchase batteries u should check its spec etc size,plugs, discharge ratings.

 ken39 26 points

i think you should go to local hobby shop and ask them to change the connector. its work for me as they charge 1$

 HibridOPT 52 points

There is no problem, but yeah, you could have bought a cheaper battery. To charge it, you can charge it at 1C, meaning you will charge it at 2.2Amp/Hour so 1 hour to charge. I charge all my batteries at 1C to get better lifespan, if you want you can charge this one at 5C, if you have a good charger. (150W ) :p

 Skylanders 20 points

Thanks! Anyways nice to have a battery which can be used in later models as well :)

 billum2 172 points

The 40C discharge only applies for short bursts anyway. You have chosen the right battery for the job and it shouldn't get hot or puff up early in it's life cycle. Charge at 1C for longest life. Check that your charger will balance charge and do that every other charge (takes longer). Many chargers default to "charge" and you have to force them to "balance". Enjoy.

 Skylanders 20 points

I bought the Turnigy 6A charger ($20-something) Should I charge with the balance plug everytime? Will charge at 2.2A (1C)

 billum2 172 points

I would balance whenever you have the time since balancing takes a fair bit longer than a standard charge, say alternate charges. An unbalanced pack is easily damaged by over discharging a cell. Just plugging in the balance lead as well as the main leads is not enough, you must select balance charge too.

 Skylanders 20 points

Both wires are supposed to be plugged in while charging?

 HibridOPT 52 points

Yes, the small ones check each cell voltage and calibrates it, the big one gives the big charge to all of them.

 whiskey29 72 points

Its never an overkill. Higher C lipo will hold their voltage much longer compared to lower C, in all it probably would last longer than lower C on your application because you will never torture it. DOnt forget as the capacity reduced, the max amps for the output also reduced even its 40C.

 RC_HADY 228 points

Baterie umožnuje nabíjet až 5C (11A) a vybíjet až 50C (110A) :-)

 Benny! 266 points

Yes.. the 30C is the Amps the battery can output and therefore will be more powerful than the 20c battery although it won't last as long if the power is set the same for both. Cheers

 Napstr 686 points

It depends how many amps you are drawing out - at 20c you get around 44 amp continuous but at above 30 there is a higher voltage drop therefore the power output is less generally it is good to calculate maximum continuous amps drawn by your motor prop combination and add 20-30pcnt then choose a c rating that is around that figure.

 rastafly 17 points

real good for my warbirds 1100mm perfect power !

 extremeflyer 12 points

usually didn't feel any different for beginner, 30c is more powerful for 3d heli flying.

 Bradley 1 points

multiply the c number times the capacity of the battery. The C number is the maximum amount of amps the battery will discharge. 2200 mah= 2.2 amps. 2.2(amps)x40(C)= 88. So a 2200mah 40c battery can power an esc up to 88 amps.

for hk450 the best battery ever

 Vulture231 59 points

I use them on a stock T-Rex 450 Sport V2. They are great. I also have 2 expensive Hyperions. Cannot tell the difference in fly time. The Hyperions will probable last longer (they should considered the price) but after 20 or so flights the Turnigy's are doing just fine. So yes, very suitable.

 Funprise 415 points

running mine on flat curve 100pcnt flies 6 mins on this awesome lipos. with 13t pinion on hyperion 2221-8 motor.

 Piermaria 22 points

This Lipo battery is excellent for use with T-Rex 450. It is more powerful than requested also in strong 3d flight and it has the best quality at the better price.

 Pascal 14 points

Hello, those are correct. For long life span

 Peter 66 points

its pretty much the standard lipo wor this heli.
great punch and duration.

 cuban8 94 points

Use them on my HK450 & Mini Titan.....brilliant Lipo.
