Battery Equalizer

The Battery Balancer equalizes the state of charge of two series connected 12V batteries, or of several parallel strings of series connected batteries.
When the charge voltage of a 24V battery system increases to more than 27V, the Battery Balancer will turn on and compare the voltage over the two series connected batteries. The Battery Balancer will draw a current of up to 1A from the battery (or parallel connected batteries) with the highest voltage. The resulting charge current differential will ensure that all batteries will converge to the same state of charge.

Battery equalizer HA01 is used for the 12V lead-acid batteries which are connected in series to keep battery voltage balance.

When two or more in-series connected batteries are in charging/discharging/free status. The battery voltages maybe become different. One battery voltage is high and one is low.

The battery equalizer will equalize/balance the battery voltage when it detect there are 20mV between two 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 same. This will improve battery’s performance and extent battery’s life time.

Battery equalizer can be used for 24V, 36V, 48V and any other N*12V battery system.

4X12V HA02 Battery equalizer

HA02 battery equalizer is used for the batteries which are connected in series to keep the voltage of batteries ar e equal when the batteries are charging or discharging. When the batteries work in series connection, the batteries voltage maybe will be not same due to the difference

of each cell chemical composition and temperature. And each battery’s self discharge rate also different. So even the batteries not work, their voltage of series batteries will be also different. These differences will cause battery lost balance, this means maybe one battery is overloaded and the other is insufficiently charged. The voltage difference will be increased with the battery repeated charge-discharge process. This will result in premature failure of the batteries.

HA02 battery equalizer is energy transfer type equalizer, it can compensate for batteries with two sides. The equ alizer starts to work when there are 10mV between two batteries. The current will flow from a higher voltage to lo w voltage,eventually reach equilibrium. It can connect with battery system with 24 hours , to keep the system en ergy balance automatically, no need manual maintenance.

HA02 battery equalizer is suitable for lead-acid batteries(VRLA), lithium iron phosphate batteries(LFP), nickel-ca dmium secondary batteries(Ni/CD), and nickel-metal hydride secondary batteries(Ni/MH). It starts work when the voltage higher than 2.4V, it means that this equalizer can be used in a single cell battery range from 2.4V to 12V. One equalizer can connect 4 batteries once a time, if battery less than the 4, the extra cable can be vacant (posi tive and negative terminal should be avoided), does not affect the equilibrium effects. The equalizer is not affecte d with battery connection way, no matter in series or in parallel, both can work.

 

Technical Data:

Battery nominal voltage 4* (2.4V/3.6V/6V/9V/12V)
Optimizing current 0-10A
Quiescent current 5mA(12V)  1.2mA(2.4V)
Dimensions 62*124*27 mm
Protection Reverse polarity protection
Under voltage lock out 1.8V

 

Installation:

Connect it as the following order:

1.Red cable connect positive/+ pole. Black cable connect negative/- pole
2.Connect the batteries as the pictures

You can connect all + pole firstly,and then – pole to avoid short circuits.

Note: 1.If there are extra cables, please leave the tubes of the terminals on it to avoid short circuits. 2.Please avoid any of the 8 terminals touching each other.
