What is the battery equalizer?
Battery equalizer is used to maintain the charge and discharge balance between each battery in the battery set connected in series or parallel. During the
operation of the battery connected in series or parallel, due to the difference in the chemical composition and temperature of the battery cells, it will cause the charging and discharging of the two batteries will be different. Even if the battery is idle, due to the different degree of self-discharge, it will cause anim balance between the batteries connected in series. During the charging process, due to the difference, one battery will be overcharged or discharged while the other is not fully charged or discharged. As the charging and discharging process is repeated, this difference will gradually increase and eventually lead to premature battery failure.
How does the heltec battery equalizer work?
Heltec battery equalizer is an energy transfer equalizer that can compensate the battery in both directions. When the voltage difference between the batteries connected in series exceeds 50 millivolts, the battery equalizer starts to work, and the current flows from the higher voltage battery to the lower voltage. Thelow battery will eventually balance the battery. It can be connected to the battery for a long time to automatically maintain the battery balance without maintenance.
Heltec Battery Equalizer is suitable for lead-acid batteries, Li-ion batteries, lithium iron phosphate batteries, nickel cadmium or nickel batteries. It can work when the voltage is higher than 7V, that is, the battery equalizer 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 in series.
The battery equalizer can be installed in multiple parallel connections and used with 48V 6V 72V 96V 110V 220V 240V batteries. Each battery equalizer corresponds to 2 batteries. Rail-type buckle installation, can easily install the module in the distribution box.
Two pairs of battery connection terminals and a pair of parallel cables are included in the product package, which is convenient for customers to quickly install.
1. Before connecting the battery equalizer, please confirm the positive and negative poles of each battery to avoid short circuit and reverse connection between the battery equalizer terminals.
2. Please measure the voltages of the two batteries ① separately to make sure that the 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 the battery type. long press the set button 5s(pic1 ), then the b00 flashes. Press theset or dowm button and choose the correct battery model no (default mode b03). after the button is not operated for 5 seconds, the system automatically saves and the battery voltage setting is completed, then connect the battery equalizerb2+ and b2- terminal to bat-2 ②.(pic.2)
4.lf need to connect more battery, you could connect multiple battery equalizer(pic3). Please connect p1 and p2 terminals of two adjacent battery equalizer in parallel3.after completing the connection of multiple battery equalizer modules, you need to wait several hours to achieve full balance between the battery equalizers.
Note:
① Two batteries must be the same type. The capacity or new old of the battery is different, which will affect the effect of the battery equalizer.
② Each equalizer corresponds to two batteries.
③ Multiple battery equalizers can be used in parallel to solve the voltage
