Standard shape is Flat (side by side) as shown in photo. Stick packs may also be constructed as a "Stick" for narrow use.

There is no optional length for XH balance ends - use XH extension.

Use only Lithium chargers with an A123/LithiumWerks mode limiting charge voltage to 3.6V per cell. An Astro Blinky for A123/LithiumWerks is highly recommended as a balancing aid for these cells.

Note: Photo shows sample Rx pack with double lead option.

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.
