We design and install lithium battery systems for recreational and commercial vessels across Darwin. Not just battery swaps — we engineer the full system to work reliably in NT's heat, salt, and humidity.

What we install:

  • Enerdrive, Invicta, Delkor and Renogy lithium batteries
  • Victron inverter/chargers and battery monitors
  • DC-DC chargers and MPPT solar regulators
  • Battery management systems (BMS)
  • Shore power integration
  • Full system wiring to marine standards

Why lithium? Lithium batteries offer significantly more usable capacity, longer lifespan, faster charging, and lighter weight than AGM. For Darwin boats running fridges, electronics, and trolling motors, the difference is night and day.

We assess your vessel's power needs first — then design a system that actually works. No guesswork, no undersized installs.
