Product Features:


1. Automatically identify system voltage.


2. Charging procedures for sealed, colloidal and vented lead acid battery and lithium battery are optional.


3. Improved three-stage PWM charging algorithm enables an equalizing charge for the battery regularly or when it is over discharged, effectively preventing battery disequilibrium and vulcanization, and thereby improving battery life (except colloidal, lithium battery).


4. Temperature compensation automatically adjusts charging parameters (except lithium battery which requires an external temperature sensor).


5. Dual battery charge controller is ideal for RV, caravan, ship and other occasions.


6. Two battery simultaneous charging technology.


7. Rich charging modes allow users to easily set the battery charging priority.


8. Provide overcharge, over-discharge, over-temperature protection and reverse polarity protection.


9. Provide rich parameters settings power-down saving function, without the need for repetitive setting.


10. Graphic dot matrix LCD and 2-button man-machine interface.


11. User-friendly dynamic interface for convenient and intuitive operations.


12. Industrial level design meets the requirements of various harsh environments.


13. Backlight display; when a button is pressed, the backlight is turned on, and it will be turned off after a period.
