Battery Test System. Each channel in the BT2000 is a true potentiostat and galvanostat which provides both voltage and current control for all charging and discharging requirements. Thus, the BT2000 can handle both rechargeable and primary battery applications for all chemistries. This also enables each test channel to operate independently of the others, enabling users to run different tests on multiple channels simultaneously. PC controller. This system has four channels, a high current range of +/-100A, a medium current range of +/-10A, a low current range of +/-5200mA, and a voltage range of 0-20V. 208V, 3 Ph, 50/60 Hz, 42A, CE.
