It has a higher threshold temperature for thermal runaway and less violent reactions if the battery does go into runaway.<\/p>\n<p>&#8211; LFP offers long cycle life, i.e., it is capable of a larger number of charge\/discharge cycles than the other Li-Ion chemistries.<\/p>\n<p>A123 batteries have a few disadvantages though:<\/p>\n<p>&#8211; The 26650 is only 2400mAh and the 18650 is only 1100mAh.<\/p>\n<p>&#8211; They have a nominal voltage of 3.3V versus the 3.6V\/3.7V for the li-ion batteries we normally use. At high discharge current levels the voltage can be down close to 2.5V.<\/p>\n<p>I won&#8217;t be testing the 18650 as its capacity is so low.
