RoboteQ Dual Channel High Power Digital Motor Controller AX3500 用户手册

All 3 ground (-) are connected to each other inside the controller. The two main battery 
wires are also connected to each other internally. However, you must never assume that 
connecting one wire of a given battery potential will eliminate the need to connect the 
other.

The diagram on Figure 12 show how to wire the controller to a single battery circuit and 
how to turn power On and Off.

Connect two of the three Ground tabs to the minus (-) terminal of the battery that will be 
used to power the motors. Connect the two VMot tabs to the plus (+) terminal of the bat-
tery. The motor battery may be of 12 to 40 Volts.

FIGURE 10. Powering the AX3500 from a single battery

Notes:

- 

The Battery Power connection are doubled in order to provide the maximum current to the controller. If 
only one motor is used, only one set of motor power cables needs to be connected. 

- 

Typically, 1, 2 or 3 x 12V batteries are connected in series to reach 12V, 24V or 36V respectively.
