Dual Battery Balancer Module
The balancer is a discrete electronic component that uses high-current MOSFETs to manage the parallel discharge of the two batteries. If the switching logic or the semiconductor gates fail, the controller cannot access the secondary energy reservoir, resulting in the system failing to 'switch' sources as one battery reaches its discharge floor. This component is the primary failure point for multi-source power management on this specific chassis.

Main Wiring Harness (Dual Battery Version)
Physical failure of the communication or power wires between the second battery tray and the balancer can prevent the system from recognizing the presence of a second voltage source. If the balancer does not receive a 'battery present' signal due to an internal break in the harness or pin corrosion, it will never initiate the switching sequence.

Battery Terminal Contact Plate
Mechanical deformation or oxidation on the terminal pins of the second battery cradle can cause high resistance. The balancer may interpret this resistance as a depleted or faulty battery and refuse to switch to that circuit to protect the motor controller from voltage sag.
