Lithium Polymer internal resistance meter determines battery life

Tuesday, December 18th, 2012

[embed]http://www.youtube.com/watch?v=Lo2obGQtks8[/embed] Here's a project that let's you measure the internal resistance of Lithium Polymer batteries. It measures the total current as the battery discharges through a 1 Ohm resistor. From the known voltage and the discharge current the internal resistance can calculated. This device can be used to measure the...
