Features two independent charging circuits for simultaneous dual battery charging.
Powerful 80-Watt circuit supporting up to 15 NiMH/NiCd cells or 6S LiPo batteries.
Monitors and balances individual LiPo cells during charge or discharge.
Supports a wide range of battery chemistries including Li-ion, LiPo, NiMH, NiCd, LiFe, and Pb.
Details the buttons (STOP, DEC, INC, ENTER, CHANNEL, BATT type) and their functions for operation.
Covers supervision, environmental conditions, surface types, and avoiding short circuits.
Lists voltage levels, max charge voltage, and discharge cut-off for LiLo, LiPo, LiHV, LiFe, NiCd/NiMH, and Pb batteries.
Emphasizes verifying capacity/voltage, avoiding extreme imbalance, and series configuration for LiPo packs.
Explains discharge purpose, avoiding over-discharge, and proper handling for Li-ion and NiMH/NiCd batteries.
Discusses the memory effect in NiCd/NiMH batteries and preference for full charge/discharge cycles.
Recommends partial discharge for lithium batteries and avoiding frequent full discharges.
Explains that new NiCd packs require approximately 10 cycles to optimize performance.
Instructions on how to swap between channel 1 and channel 2 using the CHANNEL button.
Guides on changing default values by pressing Start/Enter, using Inc/Dec keys, and saving settings.
Importance of selecting correct nominal voltage for LiFe, Lilo, LiPo, and LiHV batteries to prevent damage.
Charger automatically recognizes cell count and alerts if selected voltage differs from detected voltage.
Using 'CHK TIME' to delay detection for reviving dead batteries; use with extreme caution.
Explains trigger voltage for automatic peak detection in NiMH/NiCd batteries (5-20mV range).
Allows setting a maximum battery temperature during charge; process terminates if temperature is reached.
Inserts a time delay after charge/discharge for battery cooling (1-60 minutes).
Monitors charge time with a default 240 minutes limit to prevent overcharging.
Guides on setting charge current and nominal voltage/cell count for various lithium battery types.
Recommends a 1C charge rate for lithium batteries based on capacity (e.g., 5000mAh = 5.0A).
Automatically stops charging when a set maximum capacity is supplied to the battery.
Allows turning off individual button beeps and the musical alert tone.
Monitors incoming voltage from a 12V source and terminates operation if it drops below a set value.
Requires connecting the balance plug to the balance board for cell monitoring and equalization.
Instructions to set charge current and voltage/cell count, then confirm with START/ENTER.
Charger compares detected cell count ('R:') with selected count ('S:'); alerts on mismatch.
Pressing the 'increase' button during charging shows individual cell voltages.
Speeds up charging by reducing power reduction as battery nears nominal voltage, but may not reach full capacity.
Charges to a nominal storage voltage (e.g., 3.75V for LiPo) for long-term storage, balancing if needed.
Allows setting discharge current and final voltage, recommending 1C max discharge and manufacturer's final voltage.
Monitors individual cell voltages during storage/discharge, terminating if abnormal variations occur.
Selects LiHV battery with 3.8V nominal voltage; only supports 4.35V/cell LiHV, warning against charging 4.20V LiPo.
Instructions for charging NiMH/NiCd batteries using Auto or Manual modes, setting charge current.
Guides on setting discharge current and final voltage for NiMH/NiCd batteries.
Selects Discharge/Charge or Charge/Discharge sequence and number of cycles (1-5) for NiMH/NiCd batteries.
Sets charge current (0.1A-6.0A) and nominal voltage for Pb batteries, starting the process.
Sets discharge current (0.1A-7.0A) and final voltage for Pb batteries, starting and stopping the process.
Shows the final voltage for the selected cell type after a process.
Indicates if capacity cut-off is enabled and the set capacity value.
Shows if the safety timer is active and its set duration in minutes.
Indicates if the temperature cut-off function is enabled.
Displays external temperature when a temperature probe is connected.
Shows the present input voltage to the charger.
Displays individual cell voltages (up to 6 cells) when balance lead is connected.
Indicates incorrect polarity detection.
Indicates the battery connection was interrupted.
Indicates a short-circuit of the output termination.
Indicates the input voltage is wrong.
Voltage is lower than setting; check battery pack cell count.
Indicates an internal error in the charger.
Pack voltage is too low to charge safely; check individual cell voltages.
Pack voltage is too high to charge safely; check individual cell voltages.
Connector error; check connections at battery and charger.
Internal charger temperature is too high; allow time to cool.
Processor cannot control input current; contact customer service.
Single cell voltage is below safe levels; check each cell's voltage.
Single cell voltage is too high; check each cell's voltage.
