Micro Batteries

This page is to provide links to additional pages with discharge data on batteries for micro RC planes. Shown below is a quick summary table which shows maximum discharge rates. This table and this page is a work in progress. The max discharge rates follow the rule of thumb that many E-fliers use for LiPoly cells that the max discharge C-rate is the rate at which 50% of the cells stated capacity is returned. I use 45% to 50% as the cutoff point for this table. Those with ?? still need those discharge tests performed.

At this point this page is a work in progress. However, I have recently added energy delivered and specific energy to all the tables. Energy delivered is given in kilojoules (kJ) and is simply the product of the amp discharge each second times voltage level. This product equals watts at each point in the discharge test. Summing these across all the seconds of the test gives joules, and then dividing by 1,000 gives kilojoules, a measure of energy delivered. The other new measure given is specific energy, which is just joules divided by the battery weight in grams. This gives a measure of energy delivered relative to battery weight.

I have added the specific energy at each C-rate to the summary table below. This allows comparing cells of roughly similar weight to see which one delivers more energy relative to its weight.

I will write all this up in more detail when I have time.

Given below are links to individual pages with discharge curves and tables for individual cells.
