Frequently Asked Questions​

• 01. What is a Battery Equalizer?

  Battery Equalizer, also called battery balancer, is a specialized electronic device to keep the same volt level of battery bank during charging and discharging.

  Batteries aren’t all made equal. When many batteries are united to form a battery bank, minor variances between them might produce issues that significantly reduce the battery bank’s lifetime. By actively correcting the imbalance, the battery balancer prevents this.

  Please see the video below for actual use.

• 02. How does Battery Balancer Work?

  When two or more in-series connected batteries are in charging/discharging/free status. The battery volt maybe becomes different.

  

  One battery volt is high and one is low. The battery equalizer will balance the battery volt when it detects there are different between two batteries.

  It will transfer energy from higher volt battery to the lower volt battery. Until their battery volt almost becomes the same.

  

  This will improve the battery’s performance and extend the battery’s lifetime.

• 03. Why do Battery Banks need Equalization?

  When batteries are connected in series, their starting charge should be the same. Small variances will be ironed out through absorption or equalization charging, but substantial differences will result in damage owing to excessive gassing (induced by overcharging) and sulfating (caused by undercharging) of the batteries with the higher initial state of charge.

  Due to sulfation and drying out, an imbalance between batteries reduces battery life. The battery balancer balances the charge levels of two batteries that are connected in series.

• 04. Can I equalizing AGM / GEL / LiFePO4 / Car batteries?

  Yes, our battery balancer can working for all kinds of lead acid battery and lithium battery.

  It included AGM battery, GEL battery, Flooded battery, solar battery, lithium battery, lifepo4 battery, Nickel-Cadmium [NiCD], NiMH Battery, Car Battery, Forklift battery etc.

• 05. What’s the benefits of Battery Equalizer?

  Supex battery equalizer is a magic box for your battery bank. More benefits, please check the below.

  Supex Battery Equalizer can save much money for you

  Through improve battery performance and extend the battery lifespan, it will shorten the frequency of purchases.

  Supex battery balancer are using active balance technology. All battery energy can be released. You can get more power for your electrical appliances.

  Don’t you think it saves a lot of money for you?

  Extend Your Battery Bank Lifespan

  Without battery equalizer, your battery pack just has a small difference at first.

  Later, the small gap between batteries gets bigger and bigger. Finally, all battery strings ran out earlier than expected time.

  But after installing this device, there is no gap between your lovers. It can be working for a longer time than expected.

  Avoid Your Battery Bank Be Damaged

  The differences will result in your battery damage.

  Why?

  Because the higher volt battery will excessive gassing caused by overcharging. The lower volt battery will sulphation caused by undercharging.

  But Supex battery balancer born to solve this problem. It equalizes the state of charge of connected batteries to avoid damage.

  Small Size for Any Application Need

  Our balancer size is so small.  So you can install it on limited space. Such as battery cabinet.

  If you want to use it in your boat, it is totally ok. The balancer has dust & water sealed, suitable for harsh environments.

• 06. How to Choose Suitable Battery Balancer?

  For Supex Battery Equalizer Products series, also named BE Series, it can working for 24V battery bank to 96V battery group.

  BE24 Battery Equalizer 24V for 2pcs×12V batteries connected in series

  If you are using 24V battery group, 2pcs 12V battery connected in series, battery equalizer 24V is the best solution.

  Also it can working for 2S2P solar battery group, which 2pcs batteries connected in series and then connected in parallel as below.

  BE48 Battery Equalizer 48V for 4pcs×2.4V/3.6V/6V/9V/12V batteries connected in series

  Battery Equalizer 48V is designed for 4S battery group, which is 4pcs batteries connected in series.

  This is model is different from 24V battery balancer. It’s detects voltage from 2.4V to 12V.

  So it can working for many types of batteries, typically lead acid battery, lithium battery, etc.

  Battery Equalizer 60V / 72V / 96V for 5pcs/6pcs/8pcs×2.4V/3.6V/6V/9V/12V batteries connected in series

  If you have 5pcs / 6pcs / 8pcs batteries connected in series, you can choose BE60, BE72, BE96 battery balancer.

• 07. Can you customize the terminal and cable length?

  Yes, the standard terminal is M8 ring terminal.

  You also can customize it according to your device plug.

  

• 08. Can I buy samples to testing quality?

  Yes, no problem. But if you buy it for personal project,I advise buy it for online shop. Because we are factory and supply cargoes for company.

• 09. Can I install it on a battery pack that is in use?

  Yes, it is suitable for New Pack, also Battery Bank in Using

  It’s no doubt the equalizer can be installed on a new battery bank. But not everyone will plan ahead. If you are getting in trouble now, the battery balancer can help you.

  For 24V battery equalizer, the max optimizing current is 5A. For 48V battery equalizer, the max optimizing current is 10A. The higher the current, the greater the difference that the equalizer can optimize.

  So whatever new or old, our battery equalizers will make them working better.

• 10. Does your battery balancer use active or passive equalization?

  Supex equalizer uses an active balance technique, rather than a passive balance.

  Active balance redistributes charge between batteries during the charge and discharge cycles.

  So no energy waste when energy transfer. For more information, please click the below video.
