The Enerdrive ePOWER 12V 40A Battery Charger redefines how you manage power for multiple battery banks—delivering a true set-and-forget experience with smart, three-bank charging that protects life, efficiency, and availability when you need it most.

Three independent battery banks, one intelligent charger — the ePOWER 40A charger permanently connects to your battery banks and charges them with a multistage protocol that adapts to each bank’s needs. The design features isolated charging for bank 1, separate from banks 2 and 3, so you never cross-charge or compromise performance between groups of batteries.

• Multistage charging ensures fast, safe replenishment while maximizing cycle life across all banks.
• Programmable battery bank 1 can follow a different charging algorithm than banks 2 and 3 for tailored care of diverse chemistries or use cases.
• Current control offers a user-adjustable output, so you can scale the charger to suit your available power source and generator size—ideal for tight power margins in RVs, boats, or off-grid setups.
• Smart charging automatically modulates output based on loads connected to your banks, avoiding wasted energy and heat.
• Wide AC input range supports 110V/60Hz or 240V/50Hz, keeping you operational in different regions without juggling adapters.
• LED display provides a clear set-and-select menu and live charger status for quick, intuitive monitoring.
• Silent mode switches off the cooling fan for night-time operation or quiet environments. Activation drops charge output by half and locks the fan for up to 12 hours.
• Integrated temperature sensor with a 3-meter cable helps protect battery health by allowing the charger to react to temperature changes in real time.
• 5-year Australian warranty underscores a commitment to dependable support and long-term service.
• Direct-from-supplier shipping ensures reliable delivery with local support, so you’re covered from purchase to installation.

This item is shipped directly from our local suppliers, with the EN31240 model delivering a robust, durable charging solution for demanding multi-bank configurations. Whether you’re powering a fleet of golf cart batteries, a yacht’s energy system, or a remote cabin’s solar storage, the ePOWER 12V 40A Charger provides precise control, extended battery life, and peace of mind.

Key use cases

• Off-grid cabins and RVs needing reliable, multi-bank charging that protects different battery types or ages.
• Marine applications where isolated banks prevent cross-contamination between starting and house batteries.
• Solar-powered systems with generators or shore power, where adjustable output aligns with available power sources.
• Workshops and fleets requiring a maintenance-charge routine that reduces battery stress while delivering consistent performance.

What sets it apart? Unlike single-bank chargers, the ePOWER 40A charges three banks independently, with programmable bank 1 and adaptive output that responds to real-world loads. Its combination of multistage intelligence, regional power compatibility, and user-focused features makes it a practical, long-term investment for anyone relying on reliable 12V battery storage.
