Hello everyone
I m studying a method of accu capacity measurement. but I have not a circuit that discharge the battery at const current. Everyone help me, please
sorry for my english

 

How much current?
Do you need a circuit which will automatically stop when the battery voltage drops to some threshold value?
Will the timing be automatic or done manually?

I need a automatic circuit. Could you help me. thank you verymuch

So what kind of voltage and current are you talking about?
You need a power transistor, a load resistor,a voltage comparator, and a reference voltage. Turn off the power transistor using the output of the comparator when the expected voltage level is reached.
Something like this to start with?
Or buy one already made? http://www.all-battery.com/TenergyI...22_a_7c01444&gclid=COHpopfM9csCFY9ffgodr4YKpg
