The Sigma EQ Evo employs an individual-cell-voltage balancer. It isn’t necessary to connect an external balancer for balance charging. Adaptable to various type of lithium batter y Sigma EQ Evo is adaptable to various types of Lithium battery, such as Li-ion, Li-Po, Li-HV and the new Li-Fe series of batteries. Fast charge mode for lithium batteries Needs to charge Lithium batteries can vary. - Page 5 Automatic charging current limit ou can set the upper limit for the charging current when charging your NiCd or NiMH battery; It is useful for NiMH batteries of low impedance and capacity in the “AUTO” charging mode. Capacity limit The charging capacity is always calculated as the charging current multiplied by time. If the charging capacity exceeds the limit, the process will be terminated automatically.

Please follow the instructions for maximum safety or the charger and the batter y can, at best, be damaged, or at worst, cause a fire.
- Page 9 Li- Po Voltage level:3.7V/cell Max. charge voltage: 4.2V/cell - Allowable fast charge current: 1C or less recommended. Consult the battery manufacturer for higher. Li- Fe Voltage level:3.3V/cell Max. charge voltage:3.6V/cell - Fast charge current: 1C or less. Consult battery manufacturer for higher. Li- HV Voltage level:3.85V/cell Max.charge voltage: 4.35V/cell - Allowable fast charge current: 1C or less Consult the battery manufacturer for higher.
- Page 10 Never attempt to charge the following types of batteries. A battery pack which consists of different types of cells (including different manufacturers). Non-rechargeable batteries (Explosion hazard). Batteries that require a different charge technique from NiCd, NiMh, Li-ion, Li-Fe, Li-HV, LiPo or Gel cell (Pb, Lead acid).
- Page 11 Charging. During the charge process,a specific quantity of electrical energy is fed into the battery. The charge quantity is calculated by multiplying charge current by charge time. The maximum permissible charge current varies depending on the battery type or its performance and can be found in the information from the battery manufacturer.

To prevent an over discharged battery from being detected incorrectly, resulting in an error, you can set a time limit for the processor to verify the cell count.
- Page 14 When the charge process starts, the integrated safety timer starts to run simultaneously. If an error is detected or the termination circuit can not detect weather the battery is fully charged or not, this function is programmed to prevent extreme overcharging. Please refer to the statement below to calculate the timer you set.

Safe timer Calculation When charging NiCd or NiMH batteries , divide the capacity by, the current,then divide the result by 11.9, set this number of minutes as the value for the safety timer setting . If the charger stopped at this time limit, about 140% of the capacity will have been fed into the battery. - Page 16 LiPo CHARGE Charging of Lithium batter y without balancing cells 2.0A 11.1V(3S) The left side of the first line shows the type of battery you chose. The value on the left of the second line of the charger is current set. After setting the current and voltage, press the button for more than 3 seconds to start the process.
- Page 17 Individual Cell Connection Diagram Pin-assignment of 4 -pin 7-pin JST-XH balance connector Fast Charging a Lithium batter y When charging lithium batteries in the fast mode the charging current will become lower towards the end of charging cycle. When the current is down to 1/5 of the current you set during the CV term, it will stop the process and eliminate the forcible requirement of the balance precision (Whether it is been connected to the balance port or not).

The processor monitors the voltage of each cell when the battery packs are in the charge process. If the voltage of any cell is abnormal, the Sigma EQ Evo will show an error message and terminate the program. If there is battery damage or disconnection, you can see the error message and press the button to know which cell is damaged. - Page 19 Pb (lead-sulphuric acid) batter y program This program is only suitable for charging a Pb (lead-acid) batteries with nominal voltage from 2 to 20V. A Pb (lead-acid) battery is completely different to a NiCd / NiMH battery. These batteries can only deliver current lower in comparison to their capacity.
- Page 20 Data memor y program For your convenience the Sigma EQ Evo has a data memory function. It automatically stores 20 operational data sets, so you can call back the data when charging. PROGRAM SELECT Select “Load Memory” from the main menu, then press the button.

Page 21: Various Information In The Program
Various Information in the program You can inquire about various information on the LCD screen during the charging process. LiLO/LiPo/LiFe/LiHV Press the button, the charger will display user’s setting. You can press the button to monitor the voltage of each cell while the battery is connected to the balance port of the charger. - Page 22 Warning and error information The Sigma EQ Evo incorporates a variety of functions for the systems to verify processes and the state of the electronics. In case of an error the screen will display the cause of error and emit an audible sound.
