Logic Battery

The MCP supports an optional logic battery. Under heavy loads the main power can dip potentially causing brown outs. The separate

logic battery will alleviate this problem. In addition a logic battery should be utilized to avoid uncontrolled behavior when the main

battery power becomes low. The logic battery maximum input voltage is 12VDC with a minimum input voltage of 6VDC. The mAh

of the battery should be determined based on the loading conditions. The BEC is supplied by the logic battery when it is attached.

Any additional electronics attached to the MCP and powered from the MCP will need to be accounted for when determining the logic

battery size.

Logic Battery Wiring

The MCP utilizes a 2pin JST connector for the logic battery. The mating connector can be sourced from DigiKey 455-1165-ND. The

pinout is show below.
