ATTERY BACKUP FUNCTION
The Voltario T60 generally uses its primary battery input B1 as a main power source. If the B1 voltage drops below
the configured
Voltage threshold
value, it can switch to the B2 input. In such case the source with higher voltage will
be used. As soon as the B1 voltage returns back above the threshold value (+ additional hysteresis), the T60 switches
automatically back to B1, no matter the voltage of B2 input. There are several applications where the user can benefit
from the T60:
ESC-Battery combination:
Set the
Voltage threshold
value below the voltage of the battery eliminator circuit
(BEC). In this case, the BEC output will be used exclusively while the secondary input (B2) will act just as a
backup battery. Please note that both the ESC BEC and the backup battery must handle the full load of the
attached servos.
Equal dual battery discharging:
Set the
Voltage threshold
value above the maximum battery voltage. Both
batteries will be discharged equally keeping equal voltage. The batteries have to be of the same chemistry,
number of cells and similar capacity. Set the
Voltage hysteresis
value to correspond the battery properties
(LiPol/LiIon – high or medium, LiFe – medium or low).
The T60 always drains power from a single battery input. This solution is robust against a spontaneous battery
shortcut. The active battery input is marked with a red LED.
B
ATTERY CHARGING CIRCUIT
The Voltario T60 contains a simple battery charging circuit designed for 2S Li-XXX without balancing. The charging
may be optionally enabled to keep the backup battery (B2) always ready without the need to remove it from the
model (however, we recommend to charge the battery with a balancer at least once in a month). Several safety
conditions are used during the charging:
The B1 voltage must be higher than the B2 voltage and the B1 must be selected/indicated by the LED.
The B2 voltage must be within the specified limits (5.5V - 8.3V for LiPol/LiIon; 5.0V – 7.1V for LiFe). The T60
never charges to a full capacity.
The voltage difference must be lower than 5V.
The temperature must be below 70°C.
If using with R3/RSW Wireless Switch you
have to change setting of the Voltario T60
from "Touch" to "Electronic" setting.
For long term storage backup battery has
to be disconnected due to constant load of
the R3/RSW Wireless Switch.
