Optimised operating software
Sigma EQ Eco II features an AUTO function that automatically sets the current level while charging or discharging.
For Lithium batteries, it can help prevent overcharging which may lead to an explosion due to user error, and can
disconnect the circuit automatically and alarm when detecting any malfunction.
Many settings can be configured by the user.
Internal independent lithium battery balancer
Sigma EQ Eco II employs an individual-cell-voltage balancer. It isn’t necessary to connect an external balancer for
balance charging.
Balancing individual cells and battery discharging
During the process of discharging, Sigma EQ Eco II can monitor and balance each cell of the battery individually.
An error message will indicate and the process will be terminated automatically if the voltage of any single cell is
abnormal.
Adaptable to various type of lithium batteries
Sigma EQ Eco II is adaptable to various types of Lithium batteries, such as Li-ion, Li-Po, Li-HV and the new Li-Fe.
Fast and storage modes of lithium batteries
The purpose to charge a Lithium battery varies, “fast“ charge reduces the duration of charging, whereas “store“
state can control the final voltage of your battery, enabling the storage and protection of your battery over long
period of time.
Maximum safety
Delta-peak sensitivity: The automatic charge termination program is based on the principle of Delta-peak voltage
detection. When the battery’s voltage exceeds the limit, the process will be terminated automatically.
