Dual battery PWM charge controller 20A

Description

1. Automatic identification of system voltage.

2. Charging program for sealed batteries, gel batteries, lead-acid batteries and lithium batteries are available.

3. An upgraded 3-stage PWM charging algorithm is adopted. Overdischarge or application of an equalizing charging to the battery regularly can effectively prevent the battery from non-equalization and sulfuration and extend the lifespan of battery.

4. Featuring a temperature compensation function, the controller can automatically adjust charging parameters.

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

6. Two battery simultaneous charging technology.

7. A variety of charging modes.

8. It provides overcharge, over-discharge, overheat protection and reverse electrode connection protection.

9. The product adopts a dot-matrix graphic LCD screen and a human-machine interface with two switches.

10. The humanization design of interface ensures users can use the product conveniently.

11. With an industrial grade design, the product can function well in various tough situations.

12. Backlight display: When a button is pressed, the backlight is turned on, and it will be turned off after several minutes.
