What is the Battery Equalizer?

Battery equalizer is used to maintain the charge and discharge balance betweeneach battery in the battery pack connected in series or parallel. During the

operation of the battery connected in series or parallel, due to the difference inthe chemical composition and temperature of the battery cells, it will cause Thecharging and discharging of the two batteries will be different.Even when thebattery is idle, due to the different degree of self-discharge, it will cause animbalance between the batteries connected in series. During the chargingprocess,due to the difference, one battery will be overcharged Or discharge,while the other is not fully charged or discharged.As the charge and dischargeprocess is repeated, this difference will gradually intensify, eventually leadingto premature battery failure.

How Does the Heltec battery equalizer works?

Heltec battery equalizer is an energy transfer equalizer that can compensatethe battery in both directions. When the voltage difference between the batteriesconnected in series exceeds 50 millivolts, the battery equalizer starts to work,and the current will flow from the higher voltage battery to the lower voltage.Thelow battery will eventually balance the battery. It can be connected to the batteryconnected in series for a long time to automatically maintain the battery balancewithout maintenance.

Heltec battery equalizer is suitable for lead-acid batteries,Li-ion Batterybatteries, Lithium iron phosphate Batteries,nickel-cadmium or nickel-hydrogenbatteries. lt can work when the voltage is higher than 7V, that is, the batteryequalizer can be used for batteries with a single battery in the range of 7V-18V,and any number of batteries can be connected in parallel or series.

The battery equalizer can be installed in multiple parallel connections,and canbe used with 48v 6ov 72v 96V 110V 220V 240V batteries.Each battery equalizer corresponds to 2 batteries.Rail-type buckle installation,can easilyinstall the module in the distribution box.

Two pairs of battery connection terminal wires and one pair of parallel wiringare included in the product package, which is convenient for customers toinstall quickly.

1.Before connecting the battery equalizer, please confirm the positive andnegative poles of each battery to avoid short circuit and reverse connectionbetween the battery equalizer terminals.

2.Please measure the voltages of the two batteries① separately to ensure thatthe voltages of the two batteries are within the normal operating range.

3.Connect the battery equalizer B1+ and B1- terminal to Bat-1,and set thebattery type.Long press SET button 5s(pic1 ), then the B00 will flash.Press theset or dowm button and choose correct battery model No(Default mode B03).After the button is not operated for 5 seconds, the system automatically savesand the battery voltage setting is completed,then connect the battery equalizerB2+ and B2- terminal to Bat-2②.(pic.2)

4.lf need connect more battery,you could make connect several batteryequalizer(pic3).please connect P1 and P2 terminals of two adjacent batteryequalizers in parallel3.After completing the connection of multiple batteryequalizer modules, you need to wait for several hours to achieve completevoltage balance among the battery equalizers.

Note:

①Two batteries must be of the same type.The capacity or the new old of thebattery is different, which will affect the effect of the battery equalizer.

②Each equalizer corresponds to two batteries.

③Multiple battery equalizers can be used in parallel to solve the voltage

balance of multiple batteries in the battery pack.In theory, countless batteriescan be connected in parallel.
