Whats New > Batteries & Parts > A123 Cells/Packs
At long last, now you can get raw A123 cells without troubling through the ever inflating online drill pack market and not being certain your getting genuine A123 Cells (many of them no longer use the genuine article). Also, it has been reported that the factory warranty return cells are disposed of in that market. Our inventory is exclusively brand new factory fresh cells, no harvested/warranty return seconds. These cells are much easier to assemble into packs than harvested cells. Although many battery beginners offer questionable advice on these cells, we strongly urge use of a balance harness and balancer. All our packs come ready to use with the worlds most common balance connector. The XH plug readily fits the Astro Blinky. Our Favorite A123 balancer. CellPro and Thunder Power balancer owners need the "E-Flite adapter" in order to service our packs and a wide range of others.

We get way too many phone calls checking to see if our cells are genuine A123.
WE SELL ONLY GENUINE A123. We do not nor have we ever stocked any of the inferior brands.

CellPro charger owners: You own a nice unit. We run into an amazing number of customers who purchase a CellPro charger but fail to buy the adapters which allow it to be connected to a wide variety of packs. Of what value is your investment if you fail to buy the plugs to connect it to battery packs? NOTHING comes with the FMA plug except FMA packs. You will need the XH or "E-Flite" adapter in order to interface with 70% of all packs made. Our A123 packs custom built in house come with an XH plug, you will need the adapter in order to connect your charger to our and most any other pack. Would you purchaces a boat but not buy life jackets? Would you buy a trailer for your airplanes but not a hitch? BUY THE ADAPTERS.

If you want packs with Cell Pro balance connectors you'll need to send those harnesses to us with your order. We do not stock this plug.

Checking A123 RX Packs For Recharge Point Check this posting for information about checking your RX packs at the field. A look around my Radical RC Workbench site for lots of helpful information, technical articals, how-to, comentary and etc...

For checking pack voltage between flights, our best advice currently is: Leave model on after flight, plug loaded volt meter directly into pack balance plug (charge port ok but not preferred) hold load engaged, switch model off. Allow pack to drain into meter for 5 seconds, take your reading. See my blog post Checking A123 RX Packs For Recharge Point for help in this area.

A123 LIFE Insert for Hobbico Power Core MKII

The Hobbico Power Core is a nice battery holder, the only problem is it comes with a small weakish lead acid battery inside. The voltage depression of this small battery is very large resulting in a weak performance from your starter. Running a 4S A123 will just about double the torque you have now. The nominal voltage of a 4S LIFE pack is 13.2v. And, It's voltage won't depress nearly as much when your squeeze the trigger delivering more torque than ever before.

Our pack is designed to fit right into your Power Core case without any modifications. Although you could use the provided charge port in the power core, it is recommended that you use a Deans Ultra plug in the wire from the starter to the A123 Power Core battery. This way you can unplug it and charge the pack directly. Your new battery may now be charged up to 10 amps if you please. The stock lead acid charger should be discarded. Only charge with a charger in A123 charge mode.

Note, you must install a connector on your starter wire up to the task. Suggested connectors are listed below. If you order a "Set for Starter Wire", you'll get a complete set of plugs. The one you don't put on the starter wire can go on the battery if you wish to install it yourself. If so, select "None" for Output Connector. If you select an output connector, we'll put it on the pack for you ready to go. You'll still need to install a plug on your starter wire to match.

A123 Life Nano Phosphate Multi Cell 1100mah Custom Electric Flight Packs

Note, see single cell listing above for specifications for these cells. We are happy to build your A123 Electric Flight Pack for you. Packs are built by our professional in house from factory fresh cells. No worries about older manufacturing dates or earlier cell versions here. All packs include the XH Balance plug which is the worlds most popular. Fits Astro Blinky directly. Packs utilizing more than 6 cells will have multiple balance plugs.

Helpful Hint: For reasons of economizing your packs over more models if the cell count is large, it is often better to use two shorter cell counts in a series Y in the larger model so the 1/2's of the pack may be used in other smaller models easily. For example, Rather than order one 7 cell pack, order a 3 and 4 cell, plug into series Y harness then into your ESC. Now you have a 3 and a 4S pack for other smaller models.

We use only genuine A123 cells, we do not stock any of the low performance off brands.

Select your cell count, shape, wire, wire length and output connector below.

Balance Plug Note: XH balance plug is single up to 6 cells, multiple over 6 cells.

Wire Size: g=Approx Gauge, See our Silicone Wire listings for more details/strand counts etc...

Shape Note: Flat and Block Offset is most popular. Block is 2 flat packs, one over the other, Block Offset is one pack laying in the valleys of the other which is about 1/3 cell diameter thinner and wider. Stick packs (end to end soldered cells) are the most difficult to service if a cell must be replaced later. Double Stick packs are often called "Shotgun" packs. Triple Stick is like 3 Barrels in a triangle, Quad Stick is like 4 barrels 2 over 2.

Photo shows example 3 cell Triple Stick pack with XH Balance plug and Deans Ultra output plug on 480 wire.

Stick packs (end to end soldered cells) are the most difficult to service if a cell must be replaced later. Double Stick packs are often called "Shotgun" packs. Triple Stick is like 3 Barrels in a triangle, Quad Stick is like 4 barrels 2 over 2.
