SPECIAL FEATURES
Optimised operating software
Sigma EQ Evo features an AUTO function that sets the feeding current during the process of charging. For Lithium
batteries, it can help prevent overcharging, which may lead to an explosion due to user error. It can disconnect
the circuit automatically and alarm when detecting any malfunction. All the programs in this product are controlled
through two way links and communication, to achieve maximum safety and minimize problems. Many settings can be
configured by the user.
Internal independent lithium battery balancer
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 battery
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. The “fast“ charging function reduces the duration of charging, but can
reduce battery life.
Maximum safety
Delta-peak sensitivity (NiCd & NiMH): The automatic charge termination program based on the principle of Delta-peak
voltage detection. When the battery’s voltage exceeds the limit, the process will be terminated automatically.

Automatic charging current limit
You 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. You can set the maximum value.
Temperature threshold*
The battery’s internal chemical reaction can cause the temperature of the battery to rise. If the temperature limit is
reached, the process will be terminated. *This function is available by connecting an optional temperature probe,
which is not included as standard.
Processing time limit:
You can limit the maximum, total process time to avoid any possible unwanted damage to the battery if detecting
errors is unusual.
Input power monitoring
To protect a car battery used as DC input power from being damaged, the voltage is constantly monitored.
If it drops below the lower limit, the process will be ended automatically.
