High-Output 12V 40A DC-DC Charging for Dual Battery Systems
The Enerdrive EN3DC40+ is a professional-grade 12V 40A DC-DC battery charger engineered for demanding dual battery setups. Whether you're running a 4WD on extended off-road trips, a fully-loaded caravan, or a remote off-grid installation, this unit delivers intelligent multi-stage charging to keep your auxiliary battery in peak condition — even while your vehicle is on the move.
Unlike basic isolators, the EN3DC40+ uses a true DC-DC conversion process to regulate and optimise the charge voltage delivered to your auxiliary battery, regardless of fluctuations from the alternator. It also features a built-in MPPT solar input, allowing you to combine alternator and solar charging in a single compact unit — ideal for extended touring.
Key Features
- 40A DC-DC charging — high-output charging for 12V auxiliary battery systems
- Built-in MPPT solar input — combine alternator and solar charging in one unit
- Digital display — real-time monitoring of input voltage, output voltage, and charge current
- Multi-stage, multi-source charging algorithm — bulk, absorption, and float stages for optimal battery health and longevity
- Wide battery compatibility — supports AGM, Gel, Calcium, Wet/Flooded, and LiFePO4 lithium batteries
- Smart alternator compatible — works with Euro 5/6 and modern variable-voltage alternators
- Ignition-controlled operation — automatically starts and stops charging with the vehicle ignition
- Silent mode — reduces fan noise for overnight or campsite use
- Compact and robust enclosure — designed for permanent vehicle and fixed installations in harsh environments
- Reverse polarity and over-temperature protection — built-in safeguards for reliable long-term operation
