KAVAN Smart PRO T70 Dual battery switch with telemetry
expander - Instruction manual
INTRODUCTION
Congratulations on purchasing the KAVAN Smart PRO T70-C / T70-JR, a high-performance digital dual battery backer with advanced telemetry features. It
contains a charging circuit and touch switch functionality. The battery switch is ideal for mid-size models that use high-voltage servos without voltage
stabilization.
It is suitable for models equipped with dual receiver batteries or an ESC battery eliminator circuit (BEC) used as a primary power source, combined with a
small backup battery. The battery switch prefers its primary battery input, and in case of a voltage drop it automatically switches to the secondary input. The
charging circuit may be optionally enabled to charge the secondary battery from the primary input/BEC.
The device is designed to turn on/off the electronics in your model, it can replace a mechanical switch as well. The battery switch remembers its last
operating state, and if the battery is accidentally disconnected, it will automatically boot up as soon as the battery is connected again.
FEATURES
Intelligent dual battery backer/multiplexer with configurable voltage switchover threshold.
Touch switch function. Optionally, the possibility of connecting a magnetic, mechanical or electronic switch or button.
FPort, Duplex EX, S.Bus2, MSB, Hott, P²Bus telemetry support (current, voltage, capacity of both battery inputs).
Optional charging of the secondary battery.
Remembers the last operating state.
Two expansion ports allowing connecting additional Duplex EX/EX Bus sensors. Alternatively, the ports offer digital inputs/outputs
functionality.
Configuration through the transmitter or MAV Manager PC software.
Firmware updates.
