Battery Balancer Equalizer

Increase the life of batteries

This battery equaliser is used when you when have two or more 12V batteries connected in series.

It is used to keep the voltage of each battery the same.  Over time, with each charging/discharging cycle, the battery voltage may start to become unbalanced.  

Each battery will also have a different self-discharge rate. These differences will mean that eventually some of the batteries in the series may become overloaded, and others will become insufficiently charged.  

The voltage difference will increase each time the battery charge/discharge processes is repeated. This can eventually lead to premature failure of some battery packs within the battery series.

This battery equaliser will equalise/balance the battery voltages when it detects anything greater than 20mV difference between two batteries.  It will shunt current from one battery (the higher voltage one) to the other battery (the lower voltage one). It does this until the battery voltages are almost the same.  This will improve the battery performance and extend the batteries lifetime.

Suitable for multiples of 12V batteries only 

• 1 battery balancer for 2x12V in series = 24v
  • 0-5 amp equalising current between batteries.
  • LED indicator lights, show balancing current from battery A to B and vice versa
  • Low voltage disconnect of 10V.  This means if the batteries become significantly discharged, below 10V, the battery balancer stops working
  • Simple installation
