I hope you're all doing well. Today, I've got some tough news to share about a product I've been testing for quite some time now. This one really stings because it's a product I had high hopes for, and I'm genuinely disappointed to say goodbye to my dual 100 amp hour DCS lithium batteries under the bonnet of my rig.

I have to admit, there were several aspects of these lithium batteries that I absolutely loved. First off, the super-fast charging and the high charge and discharge current were a game-changer for me. Not to mention the weight and space savings I enjoyed with these batteries under the bonnet. It allowed me to make the most out of the limited space in the back of my cruiser.

I also managed to prove some skeptics wrong when it came to starting off a lithium battery and even winching off it. However, there was always one looming question mark, and that was the longevity of these batteries. You see, lithium batteries, especially LiFePO4, aren't particularly well-suited for high-heat applications, and that's a concern in the harsh Australian outback.

Before I dive into the nitty-gritty details, I'd like to ask you for a favor. It's important to me that this update reaches as many fellow travelers as possible, so please help me out by sharing, liking, subscribing, and leaving a comment below. Your engagement will boost this video's visibility, allowing more people to learn from my experience.

Alright, let's get back to the batteries. A capacity test was long overdue, and I teamed up with Joe from JS Autoelectrics to get it done. To be honest, the results were nothing short of shocking. One of the batteries suffered a whopping 30% capacity loss, while the other wasn't far behind with a 22% reduction. These figures far exceeded the promised annual loss of just 5%, as claimed by DCS.

To give you a bit of background, Joe installed the initial set of DCS 100Ah marine batteries back in November 2019. They performed well initially, but their Bluetooth functionality had consistent bugs that went unresolved. After about a year, that initial capacity test revealed significant issues, and that's when we discovered the outdated passive balance technology was the culprit.

DCS assured me that their new active balance batteries would solve these problems, but installing the dual 130Ah battery system proved impractical due to size constraints. Eventually, in February 2021, Joe installed the latest version of the 100Ah marine batteries, but a BMS firmware recall marred their performance. DCS sent replacements with updated firmware in November 2021.

Fast forward to the present, and after a few trips, I noticed a drop in battery capacity. Joe conducted a capacity test, and the results left us shocked. One battery was at a mere 50% capacity, and the other was less than 80%. Considering my remote touring habits, a battery failure in the middle of nowhere is far from ideal.

To make matters worse, Joe's experience with a 75 amp hour DCS marine battery in his Prado was similarly disappointing, with a 30% capacity loss in less than two years, even though it had low current draw and wasn't charged by the alternator.

I must mention that JS Autoelectrics has completely stopped using DCS batteries in their installations, but that's another story. Back to my situation, I reached out to DCS with my findings, and the response was far from satisfactory. They suggested moisture ingress as the cause, but we found no evidence of that when we opened the battery with 50% capacity loss.

Then, DCS surprised me by saying that my 30,000 kilometers of driving over 16 months had subjected the batteries to six times the expected punishment. Apparently, DCS measures battery lifespan in kilometers, which doesn't bode well for those of us who drive and tour extensively.

Both batteries were sent back to DCS, and I'm yet to hear from them. This left me in a bit of a bind because I have a big trip coming up in just four weeks, and I suddenly find myself without any batteries. DCS didn't have any replacement batteries to offer, which left me scrambling. Thanks to Joe's help, I'm now switching back to lead-acid under the bonnet and adding a different lithium battery in the rear of the Land Cruiser.

I'll be documenting this new setup in an upcoming video, so stay tuned for that. Overall, I'm not thrilled with how DCS handled this situation, but sometimes, it is what it is. I don't have any issues continuing to use my 150 amp hour DCS battery in the camper trailer. I'll probably run a capacity test on that too at some point. The two 130 amp hour batteries in the back of my Hilux will continue to serve, but they won't be subjected to the engine heat, which might make a difference.

In conclusion, my three-year experiment with lithium under the bonnet has shown that it can work for certain applications, but the high cost in terms of diminished capacity isn't worth it for me. If you're willing to replace your batteries every three years and have the budget for it, then go for it. However, based on my experience and Joe's, it's not a worthwhile investment for the long haul.

It's disappointing because I loved so much about lithium under the bonnet, but you never know until you try. As always, I report back to you honestly, and at this stage, lithium doesn't seem suited for high-heat under bonnet applications.

If you're currently using DCS batteries under the bonnet, I strongly urge you to conduct a proper capacity test. Don't rely solely on the state of charge displayed on the app; that won't give you the full picture. Get those batteries tested by a professional or consider purchasing capacity tests from reliable sources like eBay.

Keep in mind that this is my experience and Joe's, so if you've had different results, please share them in the comments. However, I can't stress enough the importance of conducting a proper capacity test because simply saying the batteries are working fine won't cut it.

In the end, I'm going back to lead-acid under the bonnet and a reliable lithium battery in the rear of the cruiser. It's a setup I trust and should last me for a long time. But remember, this is just my personal opinion. I'd love to hear what you think in the comments below.

4wd Sand Driving Tutorial 4: Expert Tips from a 4WD Trainer | Ultimate Tutorial

13.06.2023
by Stefan Fischer

Hey, adventure seekers! Stefan Fischer here, bringing you into the thrilling world of sand driving. With 14 years of navigating deserts and beaches, from the vast Australian outback to the picturesque shores of Tasmania, I've collected a wealth of knowledge that I'm itching to share with you. Whether you're eyeing Fraser Island for your next getaway or planning to tackle the daunting Australian deserts, this guide will arm you with everything you need to know.

Vehicle Preparation: Your Sand-Ready Steed
First things first, let's talk about your ride. You might wonder, "Do I need a monster truck?" Nope, not at all. But a few tweaks can make a massive difference. A suspension setup tailored to your load, plus at least a two-inch lift, can give your vehicle the edge, improving approach, ramp-over, and departure angles significantly. And let's not forget about tyres. The right pressure and size are crucial for that elongated footprint we're after, offering better traction and a smoother ride over soft sand.

Essential Recovery Gear: Be Prepared
Even the most seasoned drivers can find themselves in a pickle. That's where your recovery kit comes into play. While I've rarely had to use mine, thanks to careful driving and preparation, it's peace of mind to have it onboard. Essentials include traction boards (like MaxTrax or ARB Tred Pro), a sturdy shovel, soft shackles (remember, no sharp edges!), and a reliable air compressor for tyre adjustments. And, although not everyone's cup of tea, a winch offers unparalleled control and safety in sticky situations.

Mastering the Sands: Driving Techniques
The real secret sauce to sand driving? It's all in the tyre pressure. Lowering it increases your tyre's footprint, giving you more traction without the need for a heavy foot on the accelerator. Speaking of which, throttle control is your best mate in the sands. It's about finding that sweet spot where you maintain momentum without digging yourself into a hole. And yes, automatic transmissions can be a blessing here, offering smooth transitions without sacrificing engine braking or control.

Choosing the Right Tyres: A Balancing Act
In the quest for the perfect sand tyre, I lean towards mud terrain tyres. They're the Swiss Army knife of tyres, offering solid performance across various terrains, from sand to mud and everything in between. Their robust construction means fewer punctures and more confidence in remote areas. And when it comes to tyre sizes, bigger often means better. Larger tyres not only improve clearance but also allow for lower pressures, enhancing your vehicle's ability to float over sand rather than plough through it.

Final Thoughts: Sand Driving Mastery
After 14 years of sand adventures, I've learned that success boils down to preparation, the right equipment, and technique. Remember, every trip is a chance to learn and improve. So, don your explorer's hat, prepare your vehicle, and embrace the sands. Adventure awaits!

And there you have it, folks—your comprehensive guide to mastering sand driving, courtesy of 14 years on and off the beaten track. If you've found this guide helpful, why not share it with your fellow adventurers? Together, we can tackle any terrain!

A little camping hack for controlling small things in the kitchen drawer is shared in Episode 5 of our Victorian High Country 4-wheel drive adventure. We swim in the crystal clear and freezing cold mountain creeks early in the morning in Episode 5 of our Victorian High Country 4wd drive adventure. Out of Butcher country, the legendary Dingo Hill climbs steeply with sharp switchbacks, sometimes rocky steps and loose graves. McMichaels and Kelly’s hut is visited, followed by a beautiful camp by the Dolodrook River. Here my drone makes contact with two Eagles, and I lose her somewhere in the trackless wilderness. This story does have a very unexpected happy ending, so watch till the end.
