For Mark Burnett, extended off-grid camping became more challenging after moving to a new hybrid camper. His previous campers used propane refrigerators, and spending 10 to 14 days away from hookups was possible with conventional lead-acid batteries, whether solar was available or not. The new camper changed that balance. Its 12V refrigerator needed electricity around the clock, placing much more demand on the battery system. Even with four lead-acid batteries and 300 watts of solar panels, Mark found that the camper could run out of power in less than 10 days. Before the next extended trip, he decided to change the battery side of the system rather than immediately adding more solar. Why the 12V Refrigerator Changed His Off-Grid Power Needs A 12V refrigerator is convenient for camping, but unlike a propane refrigerator, it remains a continuous electrical load on the house battery system. For Mark, that difference became clear during longer stays away from shore power. His existing combination of four lead-acid batteries and 300W of solar could no longer provide the off-grid time he had been used to with earlier campers. Rather than accept shorter trips, Mark purchased two Vatrer 12V 300Ah lithium batteries. He installed one in a larger battery box and kept the second battery stored in the camper as backup. He left the existing 300W solar system unchanged. One 300Ah Lithium Battery Took Over the Job The first part of the trip provided a demanding test for the new setup. The weather was very hot, and there was very little sunshine during the first 48 hours. The 12V refrigerator continued running, while the battery supplied the camper without much help from the solar panels. After those first two days, the remaining battery capacity had dropped to around 40%. That still left Mark with usable energy while he waited for better solar conditions. The following nine days were mostly sunny. With the same 300W solar array he had been using before the battery upgrade, the system gradually recharged the Vatrer battery to more than 90% before the end of the trip. Throughout the trip, the refrigerator kept running. The Second Battery Stayed in Reserve Mark had brought two Vatrer 12V 300Ah lithium batteries because he was not yet sure how much capacity the new camper would need during a long off-grid stay. In practice, he never needed to put the second battery into service. The single 300Ah battery carried the camper through the low-sun period and then recovered as solar production improved. Keeping the second battery on board still gave Mark additional peace of mind, particularly if cloudy weather had lasted longer. He also recognized that battery capacity alone cannot replace charging indefinitely. With enough consecutive days of poor solar production, the system would eventually need another source of energy. But compared with the lead-acid setup he had been using before, he finished the trip with much more available capacity and flexibility. Keeping the Same 300W Solar Made the Difference Easy to See One of the clearest parts of Mark’s experience was that the solar system did not change during the battery upgrade. Before switching batteries, four lead-acid batteries paired with 300W of solar were not enough to keep the new 12V refrigerator running for the length of trip he wanted. After installing the Vatrer 12V 300Ah lithium battery, the same 300W solar array was able to recharge the battery once sunny weather returned. Mark is now considering increasing his solar capacity to around 500 watts, which could provide more charging margin during future off-grid trips. But the battery upgrade itself had already changed how long he could stay away from hookups with his existing solar setup. More Confidence for Extended Off-Grid Camping Mark began the trip unsure whether one 300Ah battery would be enough for a camper with a continuously running 12V refrigerator. By the end of the trip, the spare battery had remained unused. The Vatrer 12V 300Ah lithium battery carried the camper through two days of limited sunshine, continued powering the refrigerator, and recovered to above 90% with the help of the existing 300W solar system during the sunnier days that followed. For campers dealing with similar off-grid power demands, Mark’s experience shows how increasing usable battery capacity can change the balance between daily consumption and available solar charging, without requiring the entire electrical system to be redesigned at once.

For Charles Allen, race weekends mean more than getting kart #26 ready for the next session. His trailer also needs dependable electricity throughout the day for the equipment he uses in the paddock. Like many racing environments, portable gas generators are common around the pit area. They are familiar and easy to deploy, but they also bring fuel, exhaust, noise, and another engine that needs to keep running whenever power is required. After spending time around that setup, Charles began looking at whether a high-capacity lithium battery could handle more of those everyday electrical needs without depending so heavily on a generator. His solution was a Vatrer 12V 460Ah lithium battery. Why Charles Wanted Less Dependence on Gas Generators At a kart track, trailers often serve as mobile workspaces. Electrical equipment may stay on for hours while drivers wait between sessions, make adjustments, or work through delays in the schedule. For Charles, the bigger concern was how much generator use adds up across an entire paddock. One generator may not seem significant on its own, but race weekends can bring dozens of teams together, many running fuel-powered equipment at the same time. He wanted a setup that could provide the electricity he needed in the trailer without requiring a gas generator to run every time power was needed. That made battery storage a practical option rather than simply an environmental idea. A 12V 460Ah LiFePO4 Battery for the Race Trailer Charles built his trailer power setup around a Vatrer 12V 460Ah lithium battery. With 5.888kWh of stored energy, the battery gives him a substantial power reserve for use around the paddock. Instead of producing electricity on demand by burning fuel, the trailer can carry its energy with it and use that stored power throughout the race weekend. The battery also supports app-based monitoring, allowing Charles to check battery status without relying on guesswork. For a trailer that may be supplying equipment for much of the day, being able to see available power makes it easier to understand how the system is performing and when charging may be needed. The result is a quieter and simpler source of electricity for the trailer, with fewer of the day-to-day inconveniences that come with running a small combustion engine in the paddock. A Rainy Race Weekend Put the System to Work Charles shared one of his updates with Vatrer after an NHKA Kartmania weekend. Heavy rain affected Saturday's schedule, leaving the track quiet for much of the day. The race trailer, however, still needed to support the equipment inside it while Charles and the team waited for conditions to improve. According to Charles, the electrical equipment in the trailer continued working normally throughout the rainy day. That was an important part of the experience. The battery was not being tested for a few minutes in a garage. It was being used during a real race weekend, with changing weather, long periods in the paddock, and the same electrical needs Charles would normally have at the track. When racing resumed, the trailer power system was still ready to go. What Changed After Moving Away From Generator-First Power For Charles, the biggest change was how electricity fit into the race weekend. With stored battery power available in the trailer, there was less reason to treat a gas generator as the default answer every time equipment needed electricity. Power was already there when he needed it, without starting another engine and keeping it running nearby. That also changed how Charles thought about generator use across the paddock. After seeing the Vatrer battery work in his own setup, he began discussing the idea with other racers and visitors who were curious about the system. A Different Way to Power a Race Weekend For Charles, switching to battery-based trailer power was not about removing every generator from the track overnight. It was about reducing how often one needed to be used. His experience shows how a Vatrer 12V 460Ah lithium battery can fit naturally into a motorsport environment where electricity is needed for long periods but a running engine is not always necessary. For race trailer owners facing the same combination of generator noise, fuel use, exhaust, and repeated setup, a large LiFePO4 battery offers another way to keep power available throughout the day. After putting the system through real NHKA race weekends, Charles has continued using it as part of his normal trackside setup with electricity ready in the trailer before the next session even begins.

When Steve and his wife bought a manufactured home in a seasonal campground in Connecticut, a golf cart quickly became part of their daily routine. Around the campground, their 48V EZGO TXT, nicknamed “Pumpkin,” was used for simple but important trips going to the beach, picking up packages at the office, heading to the laundry room, and driving to dinner. Challenges with Lead-Acid Batteries Pumpkin originally ran on six 8V lead-acid batteries. Like many golf cart owners, Steve soon found that lead-acid power came with more maintenance than expected. The batteries needed regular distilled water refills, several fill points were hard to reach, and corrosion started building up around the battery terminals and cable connections. (Before) After a few seasons, the old lead-acid pack showed clear signs of aging. The cart struggled more on hills, the terminals continued to corrode, and the batteries seemed to need water more often. Replacing the pack with another set of lead-acid batteries was also expensive, with quotes ranging from about $1,800 to $2,485. Upgrading to a Vatrer Lithium Battery Instead of repeating the same maintenance cycle, Steve upgraded Pumpkin with a Vatrer 51.2V 105Ah lithium golf cart battery. For his EZGO TXT, the lithium battery replacement helped simplify the entire power system by replacing six separate lead-acid batteries with one cleaner, lower-maintenance battery setup. Professional Installation and Setup The installation was completed by Protek Autoworks in Somers, Connecticut. The team installed the Vatrer lithium battery, mounted the display screen where Steve could easily view it while driving, and organized the wiring for a clean, professional setup. Monitoring and Daily Use Benefits The display gives Steve a clear view of battery state of charge and estimated remaining runtime. Since most campground driving is done at partial throttle, Steve expects the battery may only need charging about once a month during regular use. The Vatrer package also helped make the 48V golf cart lithium battery conversion easier. Golf carts still need 12V power for accessories such as lights and the horn, so the included 48V to 12V converter supported those everyday functions without requiring Steve to source a separate converter. Charging and Remote Monitoring For charging, the battery comes with a 20A charger that can bring the battery back to full in a few hours. Steve can also use the app-based battery monitoring feature to check battery status remotely, which is especially useful for a seasonal campground cart that sits through the colder months. Why EZGO TXT Owners Are Switching to Lithium Long-term reliability was another reason this upgrade made sense. The Vatrer 51.2V 105Ah lithium golf cart battery is designed for up to 4000 cycles and a 10-year design life. For Steve’s campground driving routine, that means Pumpkin now has a power system built for many more seasons of use. Steve’s story shows why many golf cart owners are moving from lead-acid to lithium. If your EZGO TXT or 48V golf cart is dealing with weak hill performance, battery corrosion, frequent watering, or high lead-acid replacement costs, a Vatrer lithium golf cart battery upgrade can make the cart easier to maintain, easier to monitor, and more enjoyable to drive.
