A 25A charger on a 12V → 12V route may require about 33.3A from the source when charging at 14.4V with an assumed 90% conversion efficiency.

Estimate only: Ah ÷ (charger amps × chemistry efficiency). Source current uses the nominal source voltage, a typical charging voltage of 1.2 × nominal output (14.4V on a 12V bank) and 90% assumed conversion efficiency. Actual charging varies with battery acceptance, charging stages, temperature, derating, connected loads and alternator behaviour. Follow the battery, BMS, charger and vehicle maximum ratings.

About this range


Enerdrive Lithium Batteries, Chargers, Inverters and Complete Power Systems

Enerdrive designs 12V, 24V and 48V power equipment for caravans, motorhomes, 4WD canopies, boats and commercial vehicles. The range spans single components, such as B-TEC lithium batteries and ePOWER DC-DC chargers, through to complete pre-wired power systems. You can source the battery, charging, inversion, monitoring and distribution from one brand. This reduces compatibility questions and makes fault finding simpler if something goes wrong on the road.

What You Will Find in the Enerdrive Range

  • B-TEC lithium batteries: 12V LiFePO4 options from 100Ah to 400Ah in Slimline, Compact, G3 and IP67 Ultra formats. The range also includes 24V, 36V and 25.6V BT models with app monitoring.
  • DC-DC and multi-source chargers: ePOWER 12V 40A+ and 24V 30A DC2DC/MPPT chargers, a 12V 100A DC-DC/MPPT charger, and a 12V 80A 3 in 1 charger that combines AC, DC-DC and MPPT inputs.
  • AC battery chargers: ePOWER multi-bank chargers from 20A to 100A, plus 24V and 48V industrial chargers for fleet and materials handling use.
  • Inverters and inverter chargers: ePOWER pure sine wave inverters from 400W to 2600W, including models with RCD and AC transfer switch. The range also covers the 12V 3000W/100A inverter/charger and the ePRO Combi range in 12V and 24V.
  • Monitoring and protection: The ePRO PLUS battery monitor with NMEA 2000 interface, Simarine PICO shunts, smart battery guards, voltage sensitive relays, ANL fuse holders, busbars and remote battery switches.
  • Solar and accessories: Monocrystalline fixed solar panels from 40W to 200W, MPPT solar charge controllers, water tank level sensors, USB and DC outlets, and rocker switches.

Pre-Wired eSYSTEM Boards and Canopy Power Systems

For a faster install, the eSYSTEM pre-wired boards combine AC and DC-DC chargers, MPPT solar inputs, a transfer inverter or inverter charger, and an ePRO PLUS or Simarine battery monitor on one board. 4WD and ute owners can choose the Explorer, Adventurer, Traveller, Journeyman and Voyager canopy systems in left, right or top mount layouts, many of which are bundled with B-TEC lithium batteries. Journeyman mounting kits are listed for 2022-on Next Gen Ranger and Amarok, with or without tub rails.

Sizing Your Inverter and Charging Setup

Start by matching the inverter to the appliances you plan to run. A 600W to 1000W unit suits laptops and small loads, a 2000W to 2600W model covers kettles and microwaves, and a 3000W/100A inverter/charger adds high-current mains charging. Our guide to sizing and choosing an inverter for your RV explains continuous ratings, surge loads and transfer switch features in more detail.

Compatibility Notes

Match the system voltage across the battery, chargers and inverter. 12V, 24V and 48V models are not interchangeable. The Journeyman universal mounting kits are left-hand specific, and canopy systems are sold in fixed mounting orientations, so check your canopy layout before ordering. The 4m IEC C19-C20 AC lead is designed for the transfer inverters. Replacement temperature sensors, remotes and the 70mm² cable kits are listed for specific ePOWER and ePRO models, so confirm the part suits your unit. For marine engines, AltMount serpentine pulley kits are listed for specific Yanmar 3JH and 4JH models.

Enerdrive states a 5 year warranty on its branded products, which offers added confidence for long-term touring and commercial use.
