This kind two battery regulator reduce the extra cost of two separated solar charging system, we have several dual battery charger for your select, here list their main difference for your reference:
1. MPPT5012A-DUO / MPPT5025A-DUO: Most power charging to main battery, small power around 1A charging to the engine start battery, it is MPPT charge method, high charging efficiency;
2. SDC10 / SDC20: You can set up different charging power to two battery as you like, for example, charging main battery 80% power, charging the engine start battery 20% power; or charging main battery 50% power, charging the engine start battery 50% power, like this on........, it is PWM charge method;
3. DBC10: It is PWM charge method, it will charge main battery full then charge the engine start battery, the charging power is same, for example charging 10A to main battery, after the main battery full, it turn to charging 10A to engine start battery.
4. MPPT5012A-DUO-BT / MPPT5025A-DUO-BT, same function like MPPT5012A-DUO/ MPPT5025A-DUO, but this model with bluetooth function, you can read the battery charging current/charged capacity, and also can see PV power/voltage; load current/voltage/power from your mobile phone App.
