Battery monitor
Deep-discharging can cause permanent damage to the drive battery. To avoid this the Multi electronics constantly monitor the state of
the drive battery. The controller determines the cell count by measuring the battery voltage when it is first connected. When the power
supply voltage declines, the controller generates a visual warning (LED flashes slowly). If the voltage declines further, the controller
throttles the motor back, and eventually stops it completely. This occurs in the following stages, according to battery type:
Warning at Volts / cell
Motor throttled back at Volts / cell
Motor stopped at Volts / cell
The battery monitor can only work efficiently if the battery is fully charged when first connected. If the battery is overloaded, the battery
monitor may be triggered prematurely.
General recommendations and warnings
Multi-series speed controllers are designed exclusively for use in working models.
•
Heat is generated even when the controller is operating normally within the stated range, especially if the BEC system is in use.
•
For this reason it is important to provide an adequate flow of cooling air. Never pack the speed controller in foam rubber or heat-
insulating material.
The controller's pulsed operation generates high-frequency alternating electro-magnetic fields, and these could reduce the
•
effective range of the RC system. You can avoid this by keeping the RC receiver away from the immediate vicinity of the motor,
speed controller, and any leads connecting the two.
Keep all high-current leads as short as possible.
•
Fit the usual suppressor capacitors to the motor, but do not fit a Schottky diode, as this is destroyed by any forward-reverse
•
controller; it may also damage the speed controller.
It is essential to use a polarised connector system between battery and speed controller.
•
We wish you many hours of pleasure and success with your Multi speed controller.
