Lipo 1S High Current Discharger. How to make and test.
The performance of a 1S (3.7V) Lipo is very important, since even a small drop in voltage will have a big affect on the speed of a racing car.
To check your 1S lipo to see if it is holding up the voltage, compared to a new one, requires a high current discharger.
You can make one quite cheaply, and measure the voltages and see which holds the highest volts over 5 minutes or longer.
Also compare the capacity by seeing which discharges for the longest time, to 3.0V.
