(updated 8/31/04)

This is a list of the cells included in ElectriCalc version 2.20. You can download the complete upgrade if you have V2.0x or V2.1x and all your databases will be updated.

When ElectriCalc was first written, the cells that were included were all Sanyo. The 'R' cells have proven robust over the years, and cells such as the KR-600AE have also proven popular as a cost/performance choice for Speed 400 applications. Things aren't so simple anymore. The recent popularity of slow/park/indoor flyers has led to the use of smaller cells without the necessity of high current capability. Unfortunately, this opens Pandora's box to a zillion new choices. Stir in the new NiMH offerings and there are literally hundreds of possible choices, depending on your requirements. "I saw some cheap cells at WALK-MART. I want to use them in my park flyer. Why aren't they in the database?"

I have reluctantly added a bunch of additional cells in the database. Most of these have not been tested by me. The data is most often derived from manufacturer's data sheets. I have found the stated resistances to always be too low. I believe the AC measurement technique yields numbers that are typically 30-100% too low for ElectriCalc. I prefer a DC measurement. Most of the data below comes directly from the manufacturers, with some adjustment to the resistance value. I threw out a lot of cells that were just too heavy for their resistance and/or capacity, or there were similar cells that were much better. Some could be unobtainable. Inclusion is not the same as recommendation. Frankly, with few exceptions, I'll choose Sanyo every time.

New this revision are some Lithium Polymer cells.

There is a new column with data for cell voltage. This is actually part of the comment field for compatibility with earlier versions. Prior to V2.1, ElectriCalc only had a general voltage setting. I have included instructions for measuring the constants with simple equipment. This applies to the smaller and higher resistance cells. The low resistance, high current cells require better equipment, although conceptually measurement is the same.

Here's a little ecalc trick you can try if you only want one or two constants.
Put your cursor at the beginning of the line you want and drag to the end of the line.
Entire line (only one) should be hignlighted.

Go to the ElectriCalc motor database list and select the motor above where you want the new motor to appear.
