Frequently Asked Questions
Yes. The SRNE 12V 25A Intelligent Battery Charger supports LiFePO4 lithium leisure batteries, making it suitable for campervans, motorhomes, caravans and off-grid electrical systems. Its dedicated lithium charging profile provides controlled charging to help maintain battery performance and service life.
Yes. The SRNE 12V 25A charger supports LiFePO4, AGM, GEL and flooded lead-acid batteries. It also features a user-defined charging profile, allowing charging parameters to be adjusted for compatible battery requirements. Always select the appropriate charging profile for your battery type.
Charging time depends on battery capacity, state of charge and battery condition. For example, a 100Ah lithium leisure battery discharged to 50% would theoretically require approximately two hours at 25A. Actual charging times may be longer as charging current can reduce during the final charging stages.
Yes. The SRNE 12V 25A Intelligent Charger features built-in Bluetooth connectivity, allowing compatible smartphones to monitor charging performance and adjust supported charging parameters. This provides convenient access to charger information without needing to access the unit directly.
Yes. The SRNE 12V 25A Intelligent Charger is designed for applications including campervans, motorhomes, caravans, boats and off-grid installations. It operates from a suitable 230V mains electricity supply, making it ideal for charging leisure batteries when connected to campsite electric hook-up or another compatible mains supply.
The SRNE 12V 25A charger uses intelligent six-stage automatic charging technology to manage the charging process. It automatically adjusts charging behaviour as the battery approaches full capacity, helping prevent overcharging and maintain battery health. Depending on the selected battery profile, the charger may enter a maintenance or float charging stage.
The SRNE 12V 25A Intelligent Charger includes a lithium battery activation function designed to support compatible LiFePO4 batteries whose Battery Management System (BMS) has entered protection mode. However, successful activation depends on the battery condition, BMS compatibility and remaining voltage. A damaged or excessively discharged battery may not be recoverable.
The SRNE 12V 25A Intelligent Charger features an IP65-rated enclosure, providing complete protection against dust ingress and resistance to water jets. This makes it suitable for demanding leisure vehicle environments, although installation in a protected, adequately ventilated location is recommended. The charger should not be submerged in water.
