  Here's where you'll find the best built A123 LiFe Nanophosphate* packs available anywhere. Each pack is carefully assembled, welded, cabled and finished to order for just the way you fly. We use 1/4" wide HD nickel quad welded straps and tabs, strain relieved 18g wiring and connectors are standard. Every pack is equipped with a simple cell tap for ease of balance charging and owner cabling for your favorite charger. We 'double shrink' each pack for fuel proofing and protection of the cardboard sleeves and the outer finish is with our superb 3M Mil Spec rubberised shrink. The packs I build for you are assembled to the same exacting standards we use for the Naval Research Labs and RPV / Robotics applications worldwide. If you want the best for your baby.. it's right here!

NEW!! A123 'Combo Solution' Packages Deals with price breaks on Combp gear ordered together. Scroll to the bottom of the page for details. 
We've declined offers to purchase 'remaining' inventories of this cell as well as an offer to 'buy into' a 'final' production run based on previous experience with overseas distributors filling these 'final' orders with copies, counterfeits or sub-standard (blem) cells. I flat refuse to purchase inventory that is in any way questionable with regards to quality and source... never have, never will. The ongoing production of the ANR26650 2500ma A123 cell is unaffected by the closing of the 18650 1100ma production line, and as always; we will continue to build packs ONLY with GENUINE, 1st line, top quality FRESH inventory from A123 Systems, Inc.

on the A123 FAQ & Setup Guide



The A123 Systems Nanophosphate M1 & M1A cells have proven themselves to be the most serviceable Lithium technology pack available for Mid to Extreme Giant sized R/C applications in the last decade. Here at last is a Lithium Technology that is stable, won't burn your plane, shop or house down if you do everything right, is exceptionally durable, offers superior life expectancy, is light weight, has exceptionally low internal impedance and does not require a regulator for use with modern radio equipment and digital HD servos.


At this time we have all three of the current cell offerings from A123 Systems, assembled right here into the pack configurations most commonly used by the discerning top end competitors in Giant Scale and IMAC 3D flying. The 1100 Series is popular as a dual receiver pack and ignition pack in DA-50 powered aircraft (20-27%) and the 2500 series packs are favored in 30-45% birds for both rx & ignition applications. If your new to A123 LiFe application considerations, be sure and check our FAQ for A123 Care and feeding Info, click the link of the navbar to the left.

Accessories For A123 Setups (see the A123 Setup Guide for Installation Notes)

NEW! NoBS Batteries  'Combo Solution' UltraSwitch II for NoBS A123 packs w/ 20g 'Combo' Input Connector. Your choice of Dual 22g JR or 18g Single Jr/Univ, Deans or EC3 output connectors to the Rx!
An outstanding evolution of the UltraSwitch II, set up exclusively for us by ED for our NoBS single lead Combo 20g A123 packs and optimised for Giant Scale applications with your choice of power output configurations. This switch is set up with a 20g 3 wire twisted input that compliments our A123 Packs with the 20g Three Wire Combo Connector, allowing single cable balance charging thru the switch at up to 4 amps. No Mods, no fussing about, order our A123 Packs with the single 20g Three Wire Combo Power Feed (NO separate balance connector!) and your installation is 'plug & play' simple with this switch. The switch output is your choice of either DUAL 22g Univ/JR leads for the Rx (best for single pack, single switch installations), a Single 18g JR/Univ or a single 18g Deans or EC3 output making it ideal for Parallel A123 pack and switch setups and/or SmartFly type power boards with the Deans or EC3 plugs common in high load applications for 30-40% IMAC and Warbirds. 

$24.95 w/18g JR/Univ, $5.00 more w/ Deans or EC3
*Note: A123 rated, Designed specifically for 2nd generation single lead balance charging! If you have a 1st generation two lead balance charger, use the 'Combo' charge cord sold below; NO SEPARATE CHARGEPORT REQUIRED!

The correct A123 pack connector configuration for this switch is WITHOUT a separate 22g balance lead and WITH the Combo 20g three wire Power Feed.      

Combo 20g Three wire Balance Input for NoBS A123 packs, your choice of either Dual 22g JR univ out OR Single 18g JR/Univ out to Rx. Deans, EC3 or Multiplex $5.00 more.

This is an outstanding HD switch for 20-40% scale projects, allowing balance charging and individual cell voltage checks via the switch chargeport. With the Dual 22g JR/Univ out option the Combo Switch is especially suited to agressive 20-27% sized projects where a Single pack will be used but an additional connection to the Rx is desirable to spread out current loading. Set up with the Single 18g Univ JR connector or Deans, EC3 or Multiplex outputs it is ideal for parallel Pack configurations in the big birds when two packs and two of these switches are used to double available capacity, improve power handling and provide complete power system redundancy. Comes with 'switch guard' faceplate, closeable chargeport hood and makes for a very neat, easy to install assembly. Very light (.7oz) & durable.Max charge rate through the charge port is 4 amps.

$24.95 , + $5.00 for Deans, EC3 or Multiplex outputs.

 A123 Balance Tester
What we REALLY like about this meter are the very handy individual cell voltage check and balance status functions for A123, Li-Ion and Li-Poly packs up to 7 cells.
