HA02-12V Battery equalizer is special for 4*12V battery system.

Why you release this HA02-12V battery equalizer?
According to our customers feedback. There are many 12V battery(especially the 12V lead acid battery), when the voltage is less than 11.5V, there are few energy capacity left. If the equalizer keeping working until battery’s voltage low to 1.8V. the 12V battery will be damaged because of the over discharged. In order to protect this kinds of battery pack. we develop the new model HA02-12V equalizer which with the low voltage disconnect 11.5V.

What’s the difference between HA02 and HA02-12V?
  1, battery voltage range is different. 
      HA02 is for 4*2-12V battery, working voltage range for single battery is 1.8V-18V.
      HA02-12V is for 4*12V battery, working voltage range for single battery is 11.5-18V
  2, low voltage disconnect is different:
      HA02: 1.8V
      HA12L: 11.5V

How to choose HA02 vs HA02-12V?
  HA02 has widely voltage range of single battery voltage from 2V to 12V. It's more flexible for user have different battery requirements. 
  H02-12V is special for 12V battery, it will protect the battery when single battery voltage less than 11.5V. It's better for the battery which may in long time standby status.
