About Projecta

Projecta is a name most Australian workshops already have on a shelf somewhere.

That counts for something in a category where the buying decision is often made by whoever is doing the install. A charger from a range an auto electrician has fitted a hundred times is a charger the installer already knows how to set correctly, and one that gets diagnosed quickly if something is wrong three years later.

The DC to DC charging here does the job every dual battery setup needs. It takes whatever the alternator is putting out, which on a modern vehicle with a smart alternator is often less than a deep cycle battery needs, and turns it into a proper multi-stage charge at the voltage and profile the auxiliary bank actually wants.

Multi-stage is the part that matters. Bulk fills the battery fast, absorption tops it off carefully, float holds it there. A charger that pushes current until the voltage looks right does none of that, and a battery on one of those never quite fills and never lasts as long as it should.

Size the charger to the alternator first, because one rated above what the vehicle can supply will pull the starting battery down while it works. Then size it to the bank.

FAQs

Projecta FAQs

Who is Projecta and what is their history in the Australian 12V industry?

Projecta has been a leading name in Australian battery maintenance and power management since 1989. Operating from their headquarters in Victoria, they have focused on solving the complex challenges of delivering power to remote locations. Their reputation is built on engineering smart 12V systems that improve performance and extend battery life for 4WD, caravan, and marine travelers.

Today, they are recognized as a benchmark for sophisticated charging and power distribution solutions. By investing in local research and development, Projecta provides gear that is purpose built to handle the specific environmental tensions found across the country. This commitment to technical excellence has made them a trusted partner for both professional builders and off grid enthusiasts looking to improve their battery charging or install dual battery systems.

What makes Projecta's "intelligent" approach to battery management different?

Projecta uses an active management strategy that differentiates its gear from standard chargers that only provide a bulk power flow. Their engineering team develops multi stage algorithms that analyze the condition of your battery and adjust the current based on real time data. This response helps your battery receive the exact charge it needs to maintain peak health and longevity.

By focusing on the specific chemistry of your battery, these systems prevent common issues like heat build up or overcharging. This approach moves away from basic power delivery and toward a coordinated system that protects your investment in high value lithium or AGM storage.

Are Projecta chargers compatible with Lithium, AGM, and Gel batteries?

Yes, Projecta chargers are designed for compatibility with several battery chemistries including Lithium, AGM, Gel, and Calcium. They use selectable charging profiles that allow the unit to adjust its output to match the specific requirements of your battery bank. This versatility is a major advantage for travelers who might start with a traditional setup and plan to upgrade their power storage in the future.

The charger manages the voltage and current to provide a safe and efficient charge without the risk of overcharging or damaging sensitive internal cells. By using the correct profile for your Lithium Batteries or AGM Deep Cycle Batteries, you can maintain performance and extend the service life of your gear.

What are the benefits of the Projecta Intelli-Charge range for my battery health?

The Intelli Charge range improves battery health by using a sophisticated 8 stage charging process that does more than just top up the capacity. It actively analyzes and maintains the battery to help reverse the negative effects of deep discharge. This multi stage approach provides a tailored current at every phase of the cycle to keep your setup running efficiently.

By carefully managing the voltage, these chargers help prevent overheating while maximizing the total usable capacity of your cells. This is particularly beneficial for batteries that face heavy discharge during extended camping trips or those that have been sitting in storage between adventures. This level of maintenance keeps your power bank ready for the road and reduces the chance of unexpected failure. It is a practical way to protect your investment and maintain a functional off grid system.

How do Projecta DC-DC chargers manage alternator input in dual battery setups?

Projecta DC-DC chargers manage alternator input by converting the varied voltage from your vehicle into a steady, multi-stage charge for your auxiliary battery. This is particularly important for modern vehicles with smart alternators that often lower their output to save fuel, which can leave a secondary battery undercharged. The charger acts as a smart bridge that optimizes the current while you are driving to keep your power bank healthy.

By isolating the starter battery when the engine is off, these units prevent your vehicle from being unable to start. The 3-stage charging process makes sure your auxiliary battery reaches 100 percent capacity safely without the risk of overcharging or damage from voltage spikes.
