This is a 20 cell (24VDC) 2200mAhr Rechargeable NiMH battery pack.  These are used to power the new SuperDroid ATRs and vectoring robots.  They can also have many other uses too.  The batteries are NiMH so they do not have the memory issues common with NiCad battery packs.  The batteries are arranged in a 2x10 array of AA batteries interconnected via soldered strips and covered with a PVC wrapping (color may be different than the picture).  Two wire leads extend out of the pack.  The battery weighs about 1lb 2.7oz and measures approximately 5 3/4" x 2" x 1 1/4".

As an option you can select to get connectors for the batteries.  The connectors are sometimes referred to as dean connectors.  They can be soldered/crimped onto the wire ends and offer a great way of disconnecting the batteries for charging, etc.  The 15A connectors and 30A connectors are the same and can plug into one another, they only are for different gage wires.

You will not be able to find better prices than this for comparable NiMH battery power!.
