GENERAL OP E RATION
OUTPUT BATTERY CONNECTIONS
The Emperor L702B Pro has two sets of outputs on the front of the charger, channel
1 is on the left and channel 2 on the right. Each channel has two 4mm banana
sockets, a 7 cell balance port and a temperature sensor input.
You will need an appropriate charge lead to suit the specific connector on your
battery. Connect this charge lead to the 4mm output sockets on the charger channel
you want to use, with the positive (+) lead connected to the red socket and the
negative (-) lead to the black socket.
Only connect the battery to the charge lead AFTER the charge lead has
been connected to the charger, as the connectors on the charge lead could
touch together and cause the battery to short circuit.
When charging a Lithium pack, make sure that the balance lead is connected to the
charger. The charger has a ‘JST-EH’ type balance port, but also comes with balance
adaptor boards for JST-XH and Flight Power/Thunder Power. To use an adaptor
board, connect the supplied balance adaptor board lead to the charger and then
connect the board that works with your battery balance connector. Optional adaptor
boards for Polyquest & 4/2mm plug car packs are also available.
If the main battery power leads ONLY are connected to the output banana sockets,
without connecting the balancing connector to the balancing port on the charger, the
charger will charge or discharge the connected Lithium pack without balancing it.
We always recommend balancing a Lithium pack, because some cells may
retain more capacity than others, so over time the pack can become
unbalanced. If an unbalanced pack is then used, some of the cells will
exceed their maximum voltage when charged and others their minimum
voltage when discharged, which causes damage to the cells. When a
Lithium cell is overcharged, it can cause damage and in extreme cases can
cause a fire.

Emperor L702B Pro v1
www.LogicRC.com
The input power leads on the Emperor are supplied with 4mm
gold banana type connectors (with optional crocodile clips)
that should be connected directly to a suitable 11-28V DC
power source, ensuring that the black connector is connected
to the negative (–) and the red to the positive (+).
When the charger is initially connected to a power source, it
will ask you to confirm the maximum input power available
from the power source and allow you to adjust the percentage
of this power available to each output on the charger. This
allows the Emperor L702B Pro to deliver the highest available
power to each of the charger outputs (channels), without
overloading the power source.
Each line is selected by pressing the ‘Inc’ and ‘Dec’ buttons to
move the selection arrow up and down.
To edit a value press the ‘Enter’ button to highlight the selected value. To increase or
decrease the highlighted value, press the ‘Inc’ or ‘Dec’ buttons. Once the desired
value has been selected, press the ‘Enter’ button again to store this value.
Once the correct parameters have been entered press the ‘Esc’ button to continue to
the main screens.
THE DISPLAY
The display is broken up into 2 halves. The top half of the display shows the first
channel (Ch1) and the bottom shows the second (Ch2).
The selected channel is shown in normal text and the other in reversed out text.
Pressing the ‘Channel’ button (at any time) selects the other channel (charger).
