Note, see single cell (A123 Part#26650M1B) 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 Systems 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; JR & Futaba plugs can only be used to balance 2S battery packs!
Wire Size: g=Approximate 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.
Note, plan your order well in advance of your need. Custom multiple cell battery packs require many cells and hours to build. These packs cannot be built in a rush. Thank you for your realistic understanding and advance planning.

BALANCE PLUG OPTIONS NOTES:
If you're buying a 2S pack, select your balance plug from the 2S Balance Plug Options, then go to the next drop down and select "I chose 2S, see my choice above".
If you're buying 3S or bigger, go to the 2S Balance Plug Options and select "No selection here, because I chose 3S & Up", then select the default XH Balance (most popular)..." from the 3S Balance Plugs Options (you cannot balance a 3S or bigger battery with FJ or JR plugs).
