Quick charge-time check
Enter the Ah to replace, charger output, nominal voltage route and battery chemistry. The estimate also shows approximate source-side current.
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.
Customer stories
Absolutely stellar service from Cameron at Solar 4 RVs. Initially had him quote up a solar system for my campervan back in June 2024 and then when I was ready to purchase in November 2024 he was able to give me the best prices for every product and so I went ahead with the order.
Also gave me some tips to commission the system once I installed the products. Stoked on the Victron gear. Thanks guys!
Purchased a 12v/15a battery charger in 2023. Had issues with it today (2025). Called their info number and explained. Instantly agreed to accept it as a warranty issue and dispatched a replacement without any problems. Extremely quick service and item dispatched express courier that same day. Outstanding customer service. Thank you.
Purchased a literal boat load of electronics from them for our vessel. It all works great and they did an amazing job setting up the panel. We have had the gear a few years now and still reach out when we need help. Great customer service!

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.
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.
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.
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.
Build a matched Enerdrive power system for your caravan, canopy or boat. Choose a pre-wired eSYSTEM or a B-TEC lithium bundle to simplify installation and keep every component working on the same platform. Order your Enerdrive setup today.
