📝 Enerdrive ePOWER 12V 20A AC Smart Battery Charger

Compact, efficient, and built for precision — the Enerdrive ePOWER 20A Battery Charger delivers reliable, intelligent charging for modern 12V systems. Designed for caravans, motorhomes, boats, and off-grid setups, this fully automatic charger features independent battery bank management and adaptive charging technology to keep your batteries in top condition, wherever you are.

⭐ Essential Benefits

• Advanced Multistage Charging – Automatically performs a full charging cycle (Bulk, Absorption, Float) across three battery banks for optimal performance and battery life.
• Independent Charging Banks – Battery Bank 1 is isolated from Banks 2 and 3, allowing customised and efficient energy delivery where it’s needed most.
• Customised Charging Profiles – Program Bank 1 with its own algorithm, separate from Banks 2 and 3, for tailored charging of different battery types.
• Adjustable Output Current – Control current levels to suit smaller generators (as low as 1kVA), perfect for off-grid or mobile power setups.
• Smart Load-Based Regulation – Automatically adjusts charging output based on connected loads, preventing overcharging and promoting longer battery life.
• Universal Input Compatibility – Operates on both 110V/60Hz and 240V/50Hz AC supplies, ideal for use anywhere in the world.
• Silent Operation Mode – Disables fan activity during low-output charging for quiet night-time operation.
• Temperature-Based Charging – Includes a 3m battery temperature sensor to optimise charge performance in all climates.

⚙️ Functionality

The ePOWER 20A Charger efficiently manages up to three battery banks with intelligent load sensing and programmable control. It automatically adjusts voltage and current based on battery type, size, and condition. Bank 1 functions independently, while Banks 2 and 3 share a diode-isolated output—ensuring balanced and safe charging across your system.

The integrated LED display provides clear feedback on charging status and current output, while the programmable settings let you fine-tune the system for your exact needs.
