GoFurther Battery Box & iTECH100 Lithium Battery FAQs

How does the GoFurther Battery Box handle extreme temperatures during operation, particularly in outdoor camping scenarios?

The GoFurther Battery Box is made to tackle the harshest Australian conditions. From dusty outback tracks to humid coastal campsites, you’ll have the power you need wherever the road takes you.

It comes packed full of rugged components that are made to manage heat, dust, and vibration. That means it keeps stable performance in temperatures ranging all the way from freezing cold to peak summer. Plus, an integrated BMS and DCDC smart charger, is always keeping an eye on the operating temperature to protect the battery from heat stress.

What considerations should be made when selecting the optional Quick Release Mounting Bracket for different 4WD models?

The Quick Release Mounting Bracket is designed to fit any vehicle. From canopy trays to SUVs, you get safe, stable mounting every single time.

When thinking about placement, make sure there’s proper ventilation and secure mounting points that will handle vibration. Remember; you can always quickly remove the power station for recharging or repositioning if you need to.

Can the iTECH100 Lithium Battery be safely charged using solar panels with higher output than 300W?

Yes, it can. Connect your iTECH100 Lithium Battery with iTechworld’s advanced DCDC25 smart charger and automatically regulated input voltage. That means higher-output panels can safely be used for rapid charging. Whether you’re running portable solar blankets or roof-mounted panels, the system uses only what it needs

What are the benefits of using the plug-and-play setup of the GoFurther Battery Box compared to traditional dual-battery systems?

Traditional dual-battery setups might take hours of wiring and guesswork. The GoFurther Battery Box removes any installation stress thanks to its plug-and-play design. Pre-engineered wiring looms, fuse protection, and standard Anderson connections mean you can be adventure-ready in no time. It’s a complete, self-contained power hub built with 100% usable capacity, rapid charging, and all-in-one simplicity.

How does the built-in 50A auto-reset circuit breaker protect the system against voltage surges during a road trip?

The 50A auto-reset circuit breaker shields your gear from overloads or sudden voltage spikes. If a fault occurs, the breaker instantly cuts power to stop any damage to your system and connected devices. This makes sure every trip is as safe as can be.

Can the GoFurther Battery Box be integrated into an existing 4WD electrical setup without major modifications?

Absolutely. The GoFurther Battery Box slots into any iTechworld setup. All you have to do is connect it up to your existing alternator, solar, or mains input using standard Anderson plugs. No complex rewiring or specialist installation required.

What is the process for connecting additional batteries in parallel with the existing iTECH100 to increase capacity?

Expanding your power system has never been simpler. Link up additional iTECH100 batteries in parallel using equal-length cables and quality connectors. Plus, a built-in Bluetooth-enabled BMS automatically distributes power evenly for an easy way to double or triple your storage capacity for those longer off-grid journeys.

Are there specific types of inverters that work best with the 175A Anderson connector on the GoFurther Battery Box?

Yes, the 175A Anderson connector is engineered for high-output pure sine wave inverters up to 2000W. With this, you can ruin even the most demanding appliances like microwaves, coffee machines, or portable air conditioners.

How does the LED voltmeter display on the GoFurther Battery Box function in low-light conditions?

The LED voltmeter is bright, backlit, and always easy to read. You get an instant snapshot of your battery’s voltage so you always know what’s going on. No torch or external lighting needed.

How does the DCDC25 Charger manage power distribution when multiple devices are connected simultaneously?

The iTECHDCDC25 charger allocates current between charging your battery and powering connected accessories. This smart power management makes for stable voltage with no overloads, all while making sure your charge times stay as quick as possible.

What are the advantages of the Raptor Skin feature on the optional solar blanket, especially in rugged environments?

The Raptor Skin coating is engineered and tested in Australia’s harshest conditions. It’s built to handle UV, water, and abrasions from sand and debris, or any of the general wear and tear that comes with remote touring. Then there’s iTechworld’s high-efficiency solar cells that keep your charging reliable wherever you camp.

How does the BMS operational temperature range of the iTECH100 affect its performance in cold weather camping trips?

The iTECH100’s intelligent BMS monitors and adjusts performance as temperatures change. In cold conditions, it limits current to prevent overcharge or freezing damage, while in heat it reduces stress on the cells. Whether you’re planning for alpine mornings to desert afternoons, you’ll have power you can count on.

We are introducing our latest lithium battery, the iTECH100. A massive 100 Amps of high-performance usable DC power coupled with a custom iTechworld Battery Management System (BMS) which ensures iTechworld's lithium batteries will outperform and outlast all others on the market.

100% of the iTECH100's 100 amp capacity is usable. The internal BMS allows a peak draw of 250 amps Peak power output to a peak draw of up to 250 amps with a sustained output of 175 amps for 5 minutes, and 150 amps continuously. The iTECH100's internal BMS controls cell balancing, over and under-voltage protection, short circuit protection, thermal protection, and has over-discharge protection (safe mode).

The iTECH100 100Ah Lithium battery is the equivalent to 200Ah in lead-acid batteries (based on the standard depth of discharge of the iTECH100 (100%) and lead-acid battery (50%).

To help address the heavyweight common with traditional battery storage, the iTECH100 weighs only 13kg, which is under 1/3rd the weight of an equivalent AGM or Lead Acid battery, which usually weighs more than 60kg each.

The iTECH100 will charge up to 5x faster than lead-acid batteries. The iTECH100 can charge from just about all existing chargers with no extensive modifications required to existing systems.

The iTECH100 can cycle up to 4000 times at 50% depth of discharge. A lead-acid equivalent can cycle up to 500 times at a 50% depth of discharge. The iTECH100 has little to no self-discharge rate(≤2%), the battery can sit for long periods and will not go flat.

Designed and developed in Australia for use with caravans, camper trailers, motor homes, 4WD, boats, yachts, trucks and everything in-between. The iTECH100 will operate flawlessly in extreme heat and will handle heavy vibrations usually associated with corrugated roads.
