This is a electronic building project witch connects to the parallellport of your PC and with the included software makes it possible to measure the capasity of your transmitter and receiver battery.
The software draws a graph (see above) in realtime. The graph makes it possible to spot bad cells and learn the discharge carateristic of your batteries.
The software also compensates for the voltage losses in the wires connecting the battery to the tester for more accurate voltage readings.
The hardware consists of just a handful of components and is easy to build and calibrate.
