Important question about your batteries


Hi. I'd like everyone reading the forum to tell me what batteries you have in all your HLG/DLG. You will soon benefit directly from this information! Please help by stating for each pack you have:

Number of cells

MAH of the pack

Type (NiCAD/NiMH, etc)


Thanks in advance!

830mah Lithium Ion - 3.6v - 1 cell - .86oz

Powers my Colibri (7.3 AUW) for longer than I intend to throw it...

Would love to find a 200mah or so lion cell, talk about light.

Ive used 4 cell 110mah NICAD and 300 mah NIMH. There are some smaller NIMH available now with enough capacity. Rakm's 1 cell option is good. Always looking for something better (arent we all)

I'm using the 4 cell 150mAh 1/3AAA NiMH pack that Thermal Grommit used to sell. Not sure whose cells they are. I've been looking at a similar pack by Batteries America as a replacement. Would love to get some of the simialr sized Teig cells. They're rated at 170mAh, but you need to buy 10,000 of them.

The 1/3AAA NiMH cells are the smallest and lightest practical RX cells. They actually come in two types:

120 mAh, 3.3g, light green, www.radicalrc.com
150 mAh, 3.8g, dark green, www.batteriesamerica.com

The 120's are a bit shorter. I use them in a 3-cell pack on my small Apogees -- can't beat the 10g for the whole pack. Both the 120's and 150's are fine for polys, but too low on capacity for aileron ships IMO.

For aileron DLG's I use the AAAA cells

200 mAh, 5.1g, www.batteriesamerica.com

which also have the advantage of making an extremely small square pack -- only 0.55 x 0.55 x 1.65", not much bigger than the last two segments of your pinky.

The 170 mAh cells are also fine, but bulkier. The 300 mAh cells seem unnecessarily big, except maybe for a 6-servo ship. On my 4-servo DLG I get 75 minutes of flying from the 200 mAh's. I've never wished I had more time.

In my Wizard and Chrysalis I use the 150 mAh nicds.

In my Xterminator-Pro I use the 200 mAh nimh (AAAA size like Mark).

I get about 45 minutes from the 150 packs in the Wizard, 1 hour in the Chrysalis, and about 1 hour in the XT-Pro. Of course all of this is relative to the weather, my flying style, and the age of the pack.

I only use the Sirius Pro and Sirius Charge 200 for my packs.

270Mah NiMH 4 cell pack in a sidewinder, balances perfect and lasts forever.

Grapeape makes a good point. If you have a plane setup/designed for a speccific battery weight, then a battery that weighs significantly less would not be much use. The extra weight would have to be added if you could not move the servos around to balance.
Allthough Im sure someone would crank out a "New" design that could take advantage of the lighter batteries resulting in a lighter/better model.
Of course a 1/3 aaa with a 1000mah capacity would be nice

Although it's nice to have the flexibility of some lead shot in the nose to play with the CG. I have 1/3AAA's and a small bag of shot in my Sidewinder and almost every time I fly I take 1 piece of shot out. I think I'm getting pretty close to where I like the CG to be, and right now it's a little behind where the instructions say it should be.

I like to use my trusty 110 sanyo nicad cells in a 4 cell pack configuration when there is space available.
In tight spots I have used a 4 cell 120 mah nimh(1/3 aaa)pack with fair results.

Right now I am working on a Xterm pro poly and I am looking at using either the 1/3 aaa's or the 200 mah AAAA cells from Batteries America.

I have a couple of setups for my dlg: 3 cell 110mah nicad and a 3 cell 350mah (battery from Radio shack for $0.90 on clearance for cordless phone...). I also use that in the 2meter glider. Works great!

I do have a couple of qualcomm packs with chargers I am going to rip into and see what they have.
