Version5:

12V Automatic Battery Charging Controller Module Protection Board w/ LED Display

Feature:

2016 new version, LED display, button setting, convenient and visible to use.

When battery voltage is low at 12.4v(factory default is 12.4v, can adjust by yourself), the module start charging automatic.

The module will turn off the power at 14.4V.

Red indicator will light on when charging, indicator light off when full-charged, the relay turn off power supply input.

So that can save power.

The controller can control less than 2kw load(10A), through detecting voltage of battery, and control automatic charging.

The controller use imported voltage IC, car dedicated relay, more stable and precision.
