A123-6.6VB 2300mAh 2s1P Receiver Pack

 Geir 86 points

have no idea, but they are great Rx-batteries. I have been useing them on several large planes (1/5 scale), and will continue to change all my Rx-batteries to this one. Great unit!

 GeniolocoSinCura 89 points

this batery is a litio-ion not lifepo.

 Hella-Kopterz 129 points

They are in fact Li-Ion (Lithium-Ion) not Po4

 simonchambers 363 points

No its a LiFe, hence the nominal voltage of 6.6v. Strictly speaking a LiFe pack is a type of LiIon cell - like a LiPo is a type of LiIon cell.
Si.

 Pepeprida 6 points

this is a lion is perfect to put it direct un your reciver, have a nice day! constant 6.6

 Charlese 26 points

This battery is a life it is 3.3 volts per cell. You should set your charger to 3.3 volts not 3.7.

 Hella-Kopterz 129 points

Lithium-Ion batt. not life or lipo

 theflyiniowan 26 points

You can call it a lithium ion all u want but as an individual who owns this exact pack and has used it extensively it charges and behaves exactly as a 3.3 volt A123 cell with no problems whatsoever.

 Colin100 16 points

It depends on what receiver you have, and what voltage it can take.

 Charlese 26 points

I have this battery running a 25pcnt Yak with no regulator. Any receiver will be ok with 6.6 volts.

 Hella-Kopterz 129 points

straight to rx

 Fabio 59 points

Seu RX pode nã*o ter problema, mas o seu servos que podem queimar com 6,6volts, pois na realidade essa bateria carregada fica com 7,2V.

 rene 2 points

great upgrade from old nicad or nmhd rx packs

 frankieb 5 points

Full chg will be around 7.1 & 7.2 but it will immediately drops and stay at 6.6 as soon as a current demand is placed on. Best batt technology for receivers in this days.

 A-street 14 points

fully voltag? is 7.0 V

 alexontras 15 points

Sure, it will work. I use this battery with my $pektrum AR7000 and standard servos and works really nice.

 okiyuki 6 points

Yeap, you can use it comfortable. I'm using also.

 Ronald007 406 points

Only charge LIPO batts as LIPO and LIFE as LIFE. Try setting the voltage cutoff on your charger if it has one, and if not use a battery medic or battery analyzer to monitor and stop charging when it hits the voltage you are looking for.

 STORMY 5 points

6.6 VOLTS ARE LIFE AND SHOULD BE CHARGED AS SUCH, NOT LIPO OR NIMH!

 soebhemo 131 points

Maverick was right...just look at the battery label, it says Lithium Ion (which is should be 7,4v) but the label also printed 6,6v (which is LiFe)...it makes me confuse too..should i charge it as Life or Lion ?

 rene 2 points

100pcnt...only use LIFE charge setting

 Thiagobarreto 23 points

eu carrego a minha em um eco6 que eh parecido ao imaxb6, acredito que nao tenha problemas, estou usando ela em um piper de 2 mts em paralelo o rx e o cdi de um rcg 20cc e funciona perfeitamente! dependendo do modelo o 20 eh melhor custo beneficio, mais forte e quase o mesmo peso do 15 eu estou utilizando 2 chaves separadas

 Thiagobarreto 23 points

what is the wattage of your buggy? why this life is no doubt 6.6ve provides an optimal choice for eros ... infelizmiente not know if I would serve in his automodel, but if you think 6.6 will not have problems! greetings

 warrbirdcrasher 9 points

What is the true price? $16.73 or $31.43 ??

 simonchambers 363 points

Add to your shopping cart (when logged in already) and the price will drop to the $16 odd price.

 Jessy 122 points

Thank you Jason

 rcjets12 5 points

I have used the 2300mah A123 in my boomerang jet using 10 servos with no problems I charge after 3 flights

 Thiagobarreto 23 points

no doubt this is an optimal choice, I use a piper at 2.14 meters with 7 servos and spare battery for more than a day flight I recommend this battery!

 rcjets12 5 points

As long as your charger has an option for life batteries you would be fine.

 Thiagobarreto 23 points

Absolutely! I reload my eco6 using one and trouble free! do not forget to change the mode to life instead of lipo not to feed the battery up to 6.6v good flight!

 Shaun 22 points

Hmmm.... well did you ever need balance taps on your NiMh. Same idea. These are much more stable than lipos. I just got some for my 35 Extra 260.

 viflyer 91 points

Hmmmmmmmm...... Well, maybe you should do a BIT more research on this battery chemistry. Yes, they are more stable BUT DEFINETELY need to be balanced. Why buy one without taps when you can spend a couple of more dollars and be able to make sure the cells stay balanced??? Gee, I wonder why all the manufactureers BUT balance taps on their packs if you don't need them. LOOKS??

 eezfly 178 points

Also they need the balance leads I have 4 of the others they are great they have all the leads. this one need a little more input,good price.

 Sawdust 1605 points

This is intended as a receiver pack so it's got exactly the right plug for its intended purpose.
I do agree it would be better to have a way to ballance the cells though.

 Shaun 22 points

I viewed the page for a couple minutes and it offered me the packs for $16 each. Give it a try.

 Sepiroth 8 points

Probably just a bug in the system, the price is in fact 16$

 loren 53 points

PUT IT IN YOUR BASKIT WILL DROP 2 16 DOLLERS

 Chicane 32 points

Add it to your cart and you will get the correct price.

 rossg 133 points

Don't worry about it. When you add it to your cart it will be $16. It's an absolute bargain. BUT you can only send one of them by Parcel Post, max 3200mAh per package, as it is considered a LiPo for some strange reason. If MUST buy two at the same time it will cost a lot more for freight.

 H-KING_SCOTT 5161 points

This is no worse than a 5 cell Nicad, so should be no problem for most RX equipment, just check specs before using.

 pch.radu 67 points

nimh fully charge goes like 1.5v / cell x 5 = 7.5v so 7.2v is safe.

 Fred 5 points

It depends on the receiver. If your instructions say you can use a 5 cell nicad pack you can use this battery pack with a voltage limiter. The full charge voltage on a 5cell nicad pack and this pack are virtually identical.

 Shaun 22 points

These are run safely on giant scale all the time direct to receiver. I just got some for my 35 Extra 260 and will run them straight through a 9ch Futaba PCM receiver.

 loren 53 points

NO MENT 2 PLUG RIGHT IN TO RX U WILL LOVE IT

 H-KING_SCOTT 5161 points

Yes, exactly what it is designed to do.

 pch.radu 67 points

yes u can

 rossg 133 points

ONLY if your receiver can handle 7 volts from a fully charged A123. $pektrum and many other 2.4 Rx can take up to 9v.

 H-KING_SCOTT 5161 points

No, if they are "6v" rated, they will be fine.

 rossg 133 points

Jason, why are these A123 batteries considered as LiPo's for postage mAh limits? They are NOT Lipo batteries. If you want more than one at a time you have to pay for high cost freight. That is wrong. Regard, Ross.

 Fred 5 points

If your servo is rated for a 5cell nicad pack, this pack is OK to use. Fully charged a 5 cell nicad and this pack have the same voltage.

 Shaun 22 points

Should be fine on good quality servos. Think about the fact that 5 cell nimhs are approx 7.0V fresh charge.

 spitfire2010 640 points

Thanks Jason, the question btw was "will a fully charged pack burn out your servos etc" Damn preemptive txt.

 loren 53 points

NO IT WILL NOT

 Chicane 32 points

What's wrong in "Made in Korea". A lot of times better than "Made in China".

 ecosniper 105 points

Pejay, if you want reliable power source for your rx, get a pair of these. They are bullet proof for harsh enviroments, vibrations etc. Besides, a BEC could fail, a123 never.

 Sheko 140 points

in addition to this BEC could cause an interference with ur Rx
its better to minims the number of equipment ur using
simpler is safer

 pejay 548 points

Thanks ecosniper and Sheko for good advices. You have almost convinced me but I am a greedy bugger so will stay with the Zippy since I already bought it some time ago.

 ecosniper 105 points

Thanks peejay.

Actually i fly my 38% 150cc extra 330 with 2 pairs of a123 unregulated feeding my 8 7950hitec hungry power servos, after 4 flights i charge at 6c bursts to continue flying!! my other craft is a 830mm helicam with a123 unregulated also.
Simple
Safe
Smart

 Wheels 298 points

No fire danger either

 pejay 548 points

Wow ecosniper, that is some serious airplane - me I am only dabbling with the small guys in the 50 size glow section. Have a few gas engines which I haven't dared to venture into yet. Still a chicken.

 __Raju 2724 points

You're very much right ecosniper, people who knows about A123 they never compare them with LiPo, I also think it is best solution for Rx. Self life very long compare to LiPo and fast charging without any fear of fire/explosion makes A123 friendly for your models.

 Fred 5 points

They don't explode or catch fire if overcharged. They can be left in place during recharging no bomb shelter required.

 Shaun 22 points

No reg so less points of failure. I would go dual A123 in my 35 every time.

 loren 53 points

YA A LITTLE HEVY BUT MENT FOR BIG PLANE WERE U DO NOT HAVE TO THINK ABOUT WATE SO MUCH RX OR IGN

 olisoft 154 points

Charge with LiIon program eg 4.1V end voltage... Charger - from Accucell6 higher

 Kiku123 50 points

If you charge it with LiIon, you will kill it, they have a 3.6V/cell end voltage! A123 batteries are basically LiFePO4 batteries so charge them accordingly - LiFe settings for most chargers

 Sawdust 1605 points

They should be charged as life A123 cells.
Nominal voltage is 3.3volts per cell and charge to 3.6volts per cell usualy so charge the pack to 7.2volts. If your charger has the settings for life A123 and you set it for 2s it should charge to 7.2 volts automaticaly.

 Sawdust 1605 points

Kiku is right sorry, these are life A123 but the setting you're looking for on your chargers display is lifePO4.

 olisoft 154 points

Ah sorry, You're right Those are not LiIon like written, but LiFe. The chargers like Accucell have also LiFe programm.

 Twister PL 118 points

These are li-ion not li-fe the max volt charge is 4,1V per cell or absolute max 4,2V see the label and singel cell in the link www.link you need li-ion program to charge them if not it can be charged as li-po but life of the cells will be short.

 Kiku123 50 points

Sometimes it's advisable not to take everything in the description as pure gold. A123 is a brand name of a certain nano-technology of LiFePO4 batteries. These batteries have a nominal voltage 3,3V per cell and maximum voltage of 3,6V per cell. I haven't seen a charger that uses the full name of the battery type, everyone uses the LiFe abbreviation

 ecosniper 105 points

You are right, but i had several a123 that never failed, inclusive overcharging-discharging

 Fred 5 points

You must use a charger with LiFePO4/A123 capability. DO NOT use NiCad, NiMHd or LiPO chargers.

 Shaun 22 points

Any LiFe capable charger.

 loren 53 points

CHARG IN LIFE SETTING AT 6.6 3.3 PER SEL

 Nic 6 points

You have to use a charger that has a setting for LiFe (NOT Li-ion or LiPo) as they have different voltages per cell. LiFe has 3.3V per cell.

 STORMY 5 points

Must be charged with a charger that can select Life, do not use Lipo setting. Most modern or high quality chargers will have this facility.

 Kalps 103 points

Who knows ... Who cares.... Stick with lipos and have no dramas until the product has proven itself

 Sawdust 1605 points

No way to balance this pack without ripping it apart. I'd rather keep doing what I've been doing and buy the individual cells and incorporating a way to ballance charge them.

 britinoz 51 points

And the correct price is ????????????

 Ujjwaana 165 points

*Britinoz! Good catch!! HK is going nuts with wrong prices. First it was with latest Turnigy motors earlier this week. Now this LiPo. If you order, customer support would make only faces, as if this type of errata is our problem.

 Sawdust 1605 points

Damn! I should have bought some a couple of hours ago when they were half the price showing now.

 Wireman 343 points

Sawdust, put it the cart and you will get the half price!

 i3dm2 65 points

Add to cart - price is 16.73$.

Im just wondering why it is only 6-10C dischage. A123 cells are 30C-60C, so i guess the limitation might come from the JR style output connector.

 ecosniper 105 points

Actually 22 AWG wires (that most servo conectors have) suport 5 amps constant (good cable) and short bursts to few amps, but with voltage sag.

 davecrash 110 points

I assume with no balance connector I can't charge it with the Accucel. I would have to add that connetor to the battery.

 ecosniper 105 points

Davecrash, the accucel charges trough the balance connector only??? if not you can select charge in non balanced mode

 beau0090_99 48 points

Davecrash, you can straight charge with the accucell-6, you don't need to balance them.

 bedrock 29 points

What do you think, can i use this pack with HXT12K servos? Not too high the 8V?

 Sawdust 1605 points

bedrock, I wouldn't charge them to 8volts. I'm using a pack I made up with the individual cells and charging to the recomended 3.6 per cell (7.2 as pack) and getting about 1100 mah out of it. The absolute max charge is 4.2 but I don't think that would be a good idea whith a pack like this with no way to ballance them.

 beau0090_99 48 points

This ia a LIFE pack, not LiPO and not LiIon. They are charged to 3.3 nominally and 3.6 peak per cell. So you would see generally about 6.6V when running through the majority of the pack and max of about 7.2V You should never charge them to 8 or more volts. Make sure if you use the Accucel, you set it up as a LiFe and not the other 2. There is a way to do this, dig into it a bit.

 Sawdust 1605 points

Corection on my previous post. I'm getting around 2100mah charged to 7.2volts.

 pepiche 21 points

Hi all! This battery can it be charged with IMAX B6AC Charger? Thanks!

 Prof100 66 points

I just received my 2 cell pack and I took it apart to add a standard 2S balance tap, a special balance tape I use with my charge system and a Deans plug. I wish I could post a picture but I don't see anyway to do so. The PN label on the cell is ANR26650 M1A. It's the same PN as the individual cells you can buy from Hobbyking. Adding a standard balance tap and 3 wire connector tap (don't do it unless you have switch output the cuts out the third lead)plus a Deans femalal was a very simple. Cells were balanced perfectly as received at 3.3 volts per cell. Next step is to charge the pack and then discharge it on my CBA II battery analyzer.

 Prof100 66 points

More about the 2 cell LIFE pack PN OP-2300RX J on the label... ** As received both cells were balanced to 3.3 volts each. Only 1 two wire connector is soldered to the pack. ** Cells have tabs pre mounted on the cells which makes adding taps and charge leads very easy. ** I added a Deans style plus, a standard 2S balance tap, and 3 wire style male servo connector that works with EDC-77N Ultraswitch II which allows me to charge the pack from Ultraswitch port using a FMA Cellpro 4S charger set to A123 mode and Cellpro to JR Node/Balance Adapter (PN EDN-CP4S-JR). When finished you have to put on a piece of shrink sized for the pack. OVERALL the pack is an excellent value.

 Prof100 66 points
