Today’s Big
Birds demand big power support. Everything in the world of Giant Scale has changed, from servo current loads to flying styles
and aircraft types. Not so long ago our choices were limited by the equipment available to do the job.. now the choices and
the confusion over what's the right path to take regarding system integrity can make pack selection a mine field of opinion.
Here, we've taken steps to clear away some of the confusion and mis-information; we were the first to publish impedance
ratings along with the capacity info on all our R/C packs. Below, you'll find the best assembled in America low-impedance
packs built specifically for extreme flying with big birds. Using any of the packs on this page assures you'll not have
to worry about having the battery voltage sag when you fly your pattern 'all out'. * NOTE: A123 LiFe M1 Nanophosphate Rx & Ignition Packs are now Available! Click the navbar link to the left
and be sure and visit the A123 FAQ!
Here's where
we excel.. we build the very finest, most robust battery packs you can get anywhere tailored for Giant Scale and Aggressive
3-D applications. If your using the latest high-drain high-torque digital servos, powerboxes, ignition systems and
kero start ECU's these are the packs you are looking for.
All packs on this
page are built from the finest NiMH and Nicad cells available. All carry an internal impedance rating below
10 mOhms, and each and every one can be fast charged at the field and are designed to perform with unsurpassed
dependability in the most demanding high temp, high vibration, high current R/C environments. Exceptional Quality, No Compromises. 
Using the Impedance Rating
to pick the right pack for the way you Fly.
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.

Systems and a NiMH FAQ, check our Tech Tips page

A low cost alternative to the Sanyo
1950FAUP is the GP 2000 4/5 A HR cell. It's a bit smaller and lighter and as a result has a bit higher
impedance rating. This cell assembled into packs using the NoBS heavy duty welding and finishing techniques makes for
a very nice, robust and light power system for 27-33% IMAC 3-D parallel installations. Rated for service in
parallel with multiple digital servo's, formerly the exclusive domain of the larger FAUP's or SubC cells!
We're
also seeing quite a few of these go to larger DA Engine owners as 5 cell ignition packs where it's very light weight,
low impedance and small size complement the weight savings and long runtime requirements in the nose of the plane. |

2700 Series 'A' Size Light Weight Rx / Ignition Pack
| 4 cell pack shown |
|
Cell Size: Full 'A' Type: Medium Rate NiMH Dimensions: .67 x 1.99 Cell Weight: 1.3oz Impedance: 17 mOhms
|
The 2700AFH carries the same full-size 'A' footprint as the Sanyo Nicad 1600 at about the same impedance
rate. This makes it a suitable candidate for 3D aerobatic birds when used in parallel with digital servos. With
capacity higher than physically larger nicad Sub-C's and with significantly less weight this pack will fit where others
won't with a capacity punch above it's weight class.
* For high
drain applications (33% sized birds and larger) this pack should be run in parallel with dual switches to spread current loading
across both packs. Run as a pair, these weigh only slightly more than a single 4000 Sub-C pack and yield better than 5,000ma
of airborne capacity. |

The
Sanyo N-3000CR is the largest Nicad pack we build. Built with 'Full-C' sized cells, this is the 'Big Boy'. I keep running
into application situtations where a bunch of weight is needed up in the nose... for 1/4 scale and larger sailplanes and WWI
aircraft in particular; this pack will definitly put the weight where you need it instead of hauling around useless lead.
Rock solid, dependable Sanyo Nicad performance and simple charge support make this an on-going favorite in the military RPV
and commercial robotics applications too. -
