A Quad Phase DC-DC Step Up Converter. This unit will convert 750 W with better than 95% efficiency.

Low Voltage Cutout. This board monitors the voltage of individual cells in a battery pack and pulls the throttle low when the first one reaches its end point.

Ideal Diode. A normal diode has a small voltage drop when conducting forward current, which loses power and creates heat. This board uses a FET and control circuit to create the Ideal Diode characteristic. Working voltage and current: 90 V and 12 A.
