The SRNE DCI12-1230 30A DC-DC Battery Charger provides efficient charging of 12V leisure batteries from a vehicle's electrical system. Designed for campervans, motorhomes, caravans and off-grid applications, it helps maintain leisure battery charge while travelling, making it particularly useful for vehicles with substantial onboard electrical demands.
Unlike a conventional split-charge relay, the DCI12-1230 uses controlled DC-DC charging to deliver a regulated charging output. Its electrically isolated input and output circuits help prevent electrical interference between the vehicle supply and leisure battery system, providing dependable operation across a range of installations.
Compatible with lithium and lead-acid batteries, including LiFePO4, AGM and GEL types, the charger offers adjustable charging parameters to suit different battery requirements. Built-in Bluetooth allows convenient wireless monitoring and adjustment through a compatible mobile app.
The unit also features two selectable operating modes. Charge Mode provides controlled battery charging, while Power Mode allows the charger to operate as a regulated DC power supply for compatible electrical equipment.

Frequently Asked Questions
The SRNE DCI12-1230 is a 12V 30A DC-DC charger designed to charge a leisure battery from a suitable vehicle electrical supply. It regulates the charging current and voltage, making it an alternative to traditional split-charge relay systems in campervans, motorhomes and other vehicles.
Yes. The SRNE DCI12-1230 supports LiFePO4 lithium leisure batteries as well as conventional lead-acid, AGM and GEL batteries. Its configurable charging parameters allow the charger to be set according to the battery manufacturer's recommended charging requirements.
The DCI12-1230 accepts a 10–16V DC input, allowing it to operate with suitable 12V vehicle charging systems. Compatibility with smart alternators and Euro 6 vehicles depends on the vehicle's charging behaviour and the charger's installation and control configuration. These should be checked before installation.
Yes. The charger features built-in Bluetooth connectivity, allowing users to access compatible monitoring and configuration functions through an SRNE mobile app. This makes it easier to check charging operation and adjust supported settings without direct access to the charger.
An isolated DC-DC charger provides electrical separation between its input and output circuits. The SRNE DCI12-1230 uses this design to help reduce electrical interference between the vehicle charging supply and leisure battery system. Not all conventional battery-to-battery chargers provide this isolation.
No. The SRNE DCI12-1230 is a dedicated DC-DC charger, rather than a combined solar MPPT and alternator charger. If solar charging is required, a separate compatible MPPT solar charge controller can be installed as part of the leisure battery system.
Yes. In addition to battery charging, the DCI12-1230 features a selectable Power Mode with an adjustable 10–16V output and a maximum load current of 30A. This allows it to supply compatible 12V DC electrical equipment where a regulated power source is required.
The charger provides a rated charging current of 30A for 12V leisure battery systems, with a maximum charging conversion efficiency of 92%. Actual charging performance depends on the input supply, battery condition, configured charging parameters and operating temperature.
