GENERAL OPERATION 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. -
Page 5: Turning On & Setting The Input Power
This allows the Emperor L702B Pro to deliver the highest available power to each of the charger outputs (channels), without overloading the power source. -
Page 6: Menu Structure
MENU STRUCTURE The menu system in the Emperor L702B is summarized in the flow chart below. To move around the screens press the buttons as shown on the flow chart. Where a line selection arrow is shown on the left of a line, the ‘Inc’ and ‘Dec’ buttons can be used to move the selection arrow up or down. -
Page 7: Battery Memory Screen
BATTERY MEMORY SCREEN The battery memory screen is the main functional screen for this charger. It is used to store specific battery, charge, discharge and safety parameters, as well as being used to initiate charging, discharging, cycling/store mode functions.

Page 8: Lithium Functions And Parameters
LITHIUM FUNCTIONS AND PARAMETERS When a Lithium type battery is selected, the following functions and parameters are available. The 2 and 3 selection down arrow off the bottom of the page. Charge Store Mode Cut-off when x% of capacity is reached. Max Charge Rate TCS (Terminal Capacity Selection) - Page 9 Therefore, store mode will charge or discharge your pack to around a 60% charged state to help extend the life of your packs. CUT.TEMPER. - CUT-OFF TEMPERATURE When used with the optional temperature sensor, a safety cut-off temperature can be set, so that charging or discharging is terminated automatically if the temperature sensor detects the battery temperature rising above the selected value.

NICD/NIMH FUNCTIONS AND PARAMETERS Charge Cycle Cut-off when x% of capacity is reached. Trickle Charge Rate Cut-off if maximum time is reached ‘CHG.’ – CHARGE This line shows the charge current and the delta-peak cut-off voltage. These values can be edited by pressing the ‘Enter’ button to highlight the parameter, then the ‘Inc’ and ‘Dec’... - Page 11 CYCLE The cycle mode allows the user to both charge and discharge a battery a number of times, in order to bring it back to peak performance. Dependant on the final charge state required, you have the options to discharge then charge (D>C) or charge then discharge (C>D) the pack.

CHARGING A NICD/NIMH PACK In the flow chart below, we have shown an example of how to charge a 6 cell (7.2V) 3000mAh NiMH pack at 4.5 amps using a ‘Normal’ charge type. Press and hold the Enter button for 2 seconds to start. -
Page 14: Other Screens
In this example a ‘Normal’ charge is selected and then the ‘Enter’ button is pressed for 2 seconds to start the charge. As shown in the flow chart, pressing the ‘Mode’ or ‘Esc’ buttons at any stage moves through the different screens giving detailed information about the charge. Pressing the ‘Esc’... -
Page 15: Balancer View
If the cycle function has been used (NiCd/NiMH only), then pressing the ‘Inc’ button shows the charge and discharge statistics for the previous 10 cycles. BALANCER VIEW When a Lithium pack is connected to the charger, the balancer screen shows the balance statistics for the pack and allows the user to read off the individual cell voltages. -
Page 16: Error Messages
ERROR MESSAGES The Emperor L702B Pro has a number of error and warning messages that are designed to advise the user of any problems. When applicable, pressing the ‘Esc’ button clears the message. SAFETY PRECAUTIONS • DO NOT attempt to charge incompatible types of rechargeable batteries. This charger is designed to only charge and discharge Nickel-Cadmium, Nickel-Metal Hydride, Lithium-Ion, Lithium-Polymer, LiFePO4 and Lead-Acid batteries. -
Page 17: Lithium Ion/Polymer Battery - Safety Warnings
• Lead-Acid batteries must be placed in a well ventilated area when charging. • DO NOT attempt to charge whilst the input 12 volt battery is being charged, as the voltage supplied to the charger may be too high. LITHIUM ION/POLYMER BATTERY - SAFETY WARNINGS Ensure that the charger and battery are placed on a non-flammable surface whilst charging. - Page 18 unless the battery pack is severely mistreated, so in normal usage there is no likelihood of explosion or fire. Lithium Ion/Polymer battery packs must NEVER be discharged below 3 volts per cell (Li-Fe 2.0V) as this will result in damage to the cells. If the voltage is allowed to drop below 3 volts per cell the battery voltage may seem to recover following a charge, but the battery may not then give its full nominal capacity and a reduction in performance is likely –...
