AAA 6V 1000mAh RECEIVER PAC

[dwilfong]

I'm seeing if there is any interest in Ni-MH 6V AAA 1000mAh receiver packs. The weight is about 2.5 oz.

they can be made to any configuration needed with Futaba J connector and wrapped in heat shrink.

Please let me know if you would be interested.

The price would be $20 shipped in US.

This is the lightest and highest mAh pack you will find.

Great for those small riggers.

I would be interested in several!

Great send me a pm and let me know how many and what configuration.

I can take paypal or any other form of payment.

Keep in mind that AAA cells regardless of their capacity perform very poorly under load. This is due to a fairly high internal impedance which will result is a fairly high voltage drop under load. They are also less tolerant of overcharging, etc.

Just something to keep in mind. There is more to batteries than simply the capacity.

Take a look at this site: http://www.hangtimes.com/giantrxpacks.html

From that ste:

Most folks react to the 'capacity' rating alone as being the biggest part of their decision in selecting a pack for their big aggressive birds. This can lead to big trouble on board the aircraft. Just as cells are evaluated for capacity, in high load applications you need to take into consideration what the cells voltage performance will be when loads are applied. All battery technologies react to servo loads with a voltage drop while the load is applied. It's really very simple.. the higher the cells impedance rating, the greater the voltage drop will be while servo loads are applied. Rule of Thumb for cell selection: Impedance Ratings are like a Golf Score. The lower, the better. Aircraft in agressive aerobatic enviornments employing digital high torque servos should carry a cell impedance score of 10 mOhms or less. As an example, one of the most popular lightweight packs used in IMAC aircraft is the Sanyo HR 2700AUX.. plenty of capacity, but the impedance rate on the cell is 20 mOhms. Pretty high.. but if it's used in parallel with another 2700 pack the impedance rate is cut in half to 10 mOhms (and the available capacity is doubled). This is why you usually see this pack employed in parallel in IMAC birds and used without issues as a single pack in a giant Cub.

BTW - the internal impedance of a AAA NiMH cell runs right around 35 to 40 milliohms.

Despite being directed toward big planes the concept remains the same.

Thank's for the info Bill.

The reason for building this pack is for the small size and low weight. In the boat that I am building this pac for with the choice of servos the amp draw should be moderate.

I am offering this pack because I could not find a pac to fit my needs and must buy this batt in large lots.

This pac is for a small rigger .12 or.21 where size and weight matter and the load on batt is not agressive.

David,

I have been using that type of pack for 6+ years. They have never failed me. After checking voltage from a two day race, they read at least 5.5 volts (even my twin). If yours are comparable, I'll take four packs with the current Futaba connector. Email me at [email protected].

Thanks,

Stu

what brand cell's you using?

Thanks Stuart will send you email.

I can build pac's with any cell count or voltage you want.

Sounds perfect. As long as the amp draw is fairly low then they are a great way to go. I did not mean to make it sound like they were a bad idea, just that people need to know the limitations so they do not get themselves in a bad situation.

I've used AAA in some low draw situations where weight is an issue and they are fine.

Ive been using those t-energy cells for 2 years now. They work great.

Alden thank's for the info you don't know when you try some thing new.

Dwilfong, checkout cheapbatterypacks.com - I had them make a "custom pack" for me. They have AAA batteries from @500mAH to over 2700 mAH.... I noticed your mentioning you spent alot of time looking for powerful batteries.

I looked on that sight. The largest AAA is 800mAh. Also need bat with tabs.

There are a lot of AA bat of higher mAh but not the AAA.

When trying to build a#3 boat 5oz difference is a lot.

The price of there AAA bat pac is $23.50 shipped.

 

[dwilfong]

Have enough bat to make 3 more pacs. If you are interested please let me know.

 

[Bob Howard]

I will take two, pm sent

Bob

 

[dwilfong]

I have sold all the bat on this order.

If I get orders for 12 more packs I will order more bat.

 

[dwilfong]

This is a pic of a bat pack. weight came in at under 2.5oz.

All lead under heat shrink cover also coved with heat shrink to avoid short under cover,like I said earlier if I get enough orders to build 12 more .I will make another bat order.
