Enerdrive ePOWER 12V 40A AC Battery Charger - EN31240

Higher-output smart charging for 12V touring, marine and caravan battery banks. The Enerdrive | Dometic ePOWER 40A AC Battery Charger (EN31240) is a fully automatic multi-stage charger designed to quickly recharge and maintain up to three 12V battery banks from AC power. It is suited to Gel, AGM, Flooded and Lithium battery setups, with priority charging for Bank 1 and a clear LCD display for charge status, battery voltage, output current and fault codes. Why it works so well in Aussie touring rigs • 40A charging output gives faster AC recharge performance than the 20A model for larger battery banks. • Three-bank charging lets you manage a main house bank plus two secondary banks from one charger. • Priority charging for Bank 1 gets your main house battery bank recovered first before transitioning to the other banks. • Lithium programmable for LiFePO₄ battery systems, along with Gel, AGM, Flooded and custom/program profiles. • Silent mode disables the cooling fan for quiet overnight operation, ideal for caravans, campers and boats. • LCD display shows charger status, battery voltage, output current and fault codes without needing extra gear. • Built-in protection includes reverse polarity, over-charge, over-temperature and output short-circuit protection.
