Brand new and unused. Jeti MEZON ESC´s advanced design and software are capable of unique precise and efficient motor control. Our MEZON ESC´s are able to be fully integrated with the DUPLEX EX systems. With the DUPLEX integration, all data are measured in real time. Mezon ESC´s were designed to be able to measure the exact battery capacity used and let you set up a motor cut off point based not only on cell voltage, but also on overall battery pack capacity.
