Battery Equalizer Balancer 48V

Battery Equalizer Balancer 12/24/36/48V with Voltage Display 

2022 Model

NB - It works on a 4way communication channel - Even if one battery terminal is connected, it displays the 4 battery terminals with variance of +/- 0.05mV for the other batteries not connected yet. The actual correct battery voltages are  displayed when the 4 batteries are connected or as each battery is connected.

This is 2022 model with 4 digit display

This is latest 2022 advancement on all existing models. It is the only 4 digit display battery equalizer BMS. At a glance you will immediately see the battery voltages 

48v battery balancer/equalizer
When two or more batteries are connected in series or parallel, voltage differences begin to occur as the batteries charge and discharge. While some batteries may be overcharged, others will be undercharged. This causes battery sulfation and ultimately reduces the life span of your precious battery bank by about 2-3yrs
Once voltage difference of 2mv is detected, this energy transfer battery equalizer automatically begins to move current from higher to lower voltage battery until equilibrium is attained
This is a must for every solar installation
