1. A system for charge-discharge cycler comprising:
- a current measuring circuit unit for measuring a current wave form of charge- discharge with a voltage across a shunt according to a charge-discharge signal; and
a current conducting member combined with a shunt which is connected to the current measuring circuit unit electrically, wherein a shunt connecting groove is provided at the end of the current conducting member for insertion into the inside of the current conducting member, and a side connecting groove penetrating the current conducting member is formed perpendicular to the way the shunt connecting groove is formed, wherein the shunt comprises a first shunt body portion connected to the current measuring circuit unit by a first current conducting member;
a connecting body portion extended from one end of the first shunt body portion; and
a second shunt body portion extended from the connecting body portion and connected to the current measuring circuit unit and the second current conducting member.
