• Place both the charger and battery onto a heat—resistant, non flammable and non-conductive surface. If charging a lithium battery, use a lithium safe charging bag.
• Make sure the fan and vents of the charger are free from any and all obstructions.
• Be sure to read the entire manual and that you understand the correct settings to use for the battery you are charging or discharging. Using the incorrect settings may cause severe damage to the battery, which may include fire and explosion.
• To avoid a short circuit between the charge leads, always connect the charge leads to the charger before plugging them into the battery. When unplugging the battery from the charger, always unplug the charge leads from the battery connector leaving the leads plugged into the charger until the battery is free and clear from any connections. As a rule, leave the charge leads plugged into the charger unless disassembling for storage.
• When charging lithium batteries, always be sure to observe the actual voltage, capacity and cell arrangement (parallel or series) of the pack. Most packs have their cells arranged in a serial configuration, meaning the voltage of each cell added together. If a pack uses a parallel configuration, the overall pack voltage is equal to the voltage of a single cell within that pack. It is very important to know the battery pack’s overall voltage and capacity so you don‘t put too much voltage through a battery pack, as this will likely result in a fire or explosion. We recommend ONLY charging battery packs in series, as this has become the industry norm.

STOP! Be sure to read the above warnings and safety notes. They are very important and following them will help ensure the safety and well bein9 of you and your property. Improper operation may cause severe damage to charger and batteries, which includes possible fire and explosion.

Program Flow Chart

Charge Current

Charging a battery pack at a charge rate that exceeds its maximum allowable charge current can damage the battery and lead to fire or explosion while the battery is charging.

The C rating is the battery pack’s maximum charging/discharging capability. If a battery pack doesn‘t list its C rating, you should charge the battery pack at IC. Use the formula below to determine the amperage that a battery pack should be charged at. Battery packs are usually labeled with a “C” rating, a “mAh” rating, and a “voltage” rating, we’ll use the “C” rating and “mAh” rating to find the correct charging current (amps) for the battery pack to be charged.

NOTE: Be sure to always set the charger to the battery’s correct voltage, listed on the label (2S LiPo=7.4V, 3S LiPo=11.IV).

Dividing the pack‘s “mAh” rating by 1000 is equal the Amperage setting at IC. The formula used is (mAh/10O0)xC. See the examples below.

3000mAh pack at 1C: 3000mAh/1000= 3.OAmps
3000mAh pack at 2C: 3000mAh/1000=3.OA. 3.0×2= 6.OAmps

Power Allocation

This charger is capable of supplying a total of 200 watts (100W2) of power when plugged into a DC power supply and a total of 100 watts (100W1 or 50W*2) of power when plugged into an AC power supply. When simultaneously charging two batteries with an AC power supply, each channel will receive SOW. To help speed up AC charge times in this scenario, intellegent power allocation has been developed.

This charger offers two different allocation modes, intelligent and average. While in “intelligent allocation” mode, the charger will charge two connected batteries one at a time. A full charge current will be sent to the first battery pack set to be charged and the second connected battery will temporarily receive a minimum charge current while is awaits its turn. Once the first battery reaches full charge, then the remaining battery will receive the maximum charge current that has been programmed for that battery pack prior to charging.

While in “average allocation” mode, the charger equally distributes the charge current to each of the batteries being charged simultaneously. When plugged into an AC power supply, each channel will receive a maximum current of SOW (100W/2=50W). Intelligent allocation mode may not be beneficial while plugged into a DC power supply, since each channel will already receive a maximum current of 10OW (20OW/2=100W) in average allocation mode anyway.

Lithium Battery (Lilo/Lipo/LiFe/LiHv Modes

“Balance” charging a lithium battery

The charger balances each of the lithium cells within the battery pack being
charged. The charger will monitor each of the cell’s individual voltage and adjust
the current to each cell to ensure they are all balanced within the pack. You will
need to connect the battery to the charger’s power output plug as well as the
balance port when balance charging.

“Fast” charging a lithium battery

The charger charges the battery pack as quickly as possible without balancing
the pack. The charging current decreases as the cha rging process nears the end.
To ensure low charge times, this program eliminates certain CV processes and
does not balance the cells. This program drops the current to 1/5 of the initial
value to complete the charging process. Even though the charging current is less
than the normal charging current, it is still able to charge the battery in less time
than in balance mode.

Operation Process

This charger has two channels. Each of the two channels operates the same way. We will use the first channel to illustrate the operating process below.

When the channel led is lit constantly, you can switch the channel and system settings program by pressing the CHANNEL/SELECT key.

After the desired channel has been selected, next press the ENTER key followed by the DEC or INC keys to choose a battery type, start a program preset, select a voltage test, or enter into data storage. The battery types include LiPo, LiFe, Lilon, LiHV, NiMH, NiCD and PB batteries.

WARNING

LiHV mode only supports 4.35V Lithium batteries. Do NOT charge other batteries with this mode. Charging LiPo/LiIon/LiFe or other batteries with a cell voltage of 4.2OV or less in LiHV mode may cause possible fire or explosion.

User Settings

When using for the first time, the charger will operate according tp preset values. You can modify the parameters in the settings column for future use.

Automatic Peak detection charging

This charger uses automatic Peak detection to determine when a NiMH or NiCd battery pack is fully charged. After the battery pack reaches full charge, the charger with automatically stop charging. Peak detection works by monitoring the battery pack’s voltage, detecting the point where a battery pack “peaks”. During “peak” the packs voltage with slightly drop, triggering the charger to end the charge cycle. If the peak voltage value is set too high, there is a danger of over-charging the pack and if set too low, it may stop charging prematurely. Please refer to the specifications of the battery (NiCd default voltage: 12mv, NiMH default voltage: 7mv).

Temp cut-off program
Temp cut-off program is used to protect the charger from overheating. If the temperature gets too high, the charger will automatically turn off. The temperature cut off value can set from 60° – 80° Celsius,140° -176° Fahrenheit.

Safety timer setting
If you turn the safety timer on, the charger will stop the charge cycle when the specified amount of time has passed. While this charger uses other methods of determining when a battery is fully charged, the safety timer is a failsafe in the event the charger is unable to detect a fully charged battery from battery failure or system fault. The safety time should not be set shorter than the time the battery typically takes to fully charge, usually from 10-120min.

Capacity cut-off program
Capacity cut-off program sets the maximum charging capacity. The charger will stop the charge cycle once the maximum capacity has been reached. This is another failsafe in the event the charger fails to automatically detect peak or capacity. You can set the maximum charging capacity within the range of 10mAh to 5000mAh .

Sound setting
Beep sound: on/off; Buzzer sound: on/off.

Input power low cut-off
The acceptable DC input power is 19-26V, the program sets the lowest cut-off input voltage value from 19-26V. If the input voltage is lower than the set voltage level, the active procedure will be forced to stop.

Load factory set
Resume to the default factory settings.
