The Battery Equalizer HC01 is used for lead-acid batteries connected in series to maintain battery voltage balance.

When two in-series connected batteries are in charging/discharging/free status. The battery voltages may become different. One battery voltage is high, while the other is low.

The battery equalizer will equalize/balance the battery voltage when it detects there is 20mV between four batteries. It will shunt current from one battery (the higher voltage one) to the other battery (the lower voltage one). Until their battery voltage almost becomes the same. This will improve battery performance and extend the battery life.

installation:

Please connect the battery equalizer to the battery as follows: (Please check the pictures)

1. Red cable: Battery B positive/+ pole

2. Black cable: Battery A negative/- pole

3. White cable:  Battery B negative or Battery A positive

1. What is the working principle of the HC01 battery equalizer?
   The HC01 battery equalizer is a capability–transferred equalizer. When the voltage difference between the batteries connected in series exceeds 20 mV, the battery equalizer starts to operate, and the current flows from the higher voltage battery to the lower voltage battery. The maximum compensation current is 5A.
2. When does the battery equalizer start working?
   When the difference between the two battery voltages is less than 20mV, the battery equalizer starts to work.
3. Can the HC01 battery equalizer be used when charging or discharging?
   Yes, the battery equalizer can be used during charging and discharging, and it can balance the battery voltage.
