Building an off-grid electrical system from scratch is an intimidating project. If you are outfitting a camper van, upgrading an RV, or setting up a remote cabin, you quickly realize that buying a battery is just the first step. You then have to spend hours researching charge controllers, matching inverter wattages, and praying that the components you buy from five different brands will actually communicate with each other without frying your system.
The ExpertPower 12V 100Ah LiFePO4 Kit takes the overwhelming guesswork out of custom solar setups. Instead of forcing you to become an electrical engineer overnight, this bundle packages the core essentials—a premium lithium iron phosphate battery, a pure sine wave inverter, an MPPT solar charge controller, and an AC charger—into one cohesive, pre-matched system.
Transitioning to lithium power is a massive upgrade in terms of weight reduction and usable energy, but compatibility is where most DIYers stumble. By engineering these components to work together seamlessly, ExpertPower aims to provide a plug-and-play foundation for reliable off-grid power. Let’s look closely at how this kit performs in real-world scenarios and whether it delivers on its promise of stress-free electricity.
Key Features & Specifications
A solid off-grid system is only as strong as its weakest link. Fortunately, ExpertPower hasn’t cut corners on the core hardware. Here are the defining specifications of this bundled kit:
- Core Battery: 12V 100Ah Lithium Iron Phosphate (LiFePO4) featuring a built-in Battery Management System (BMS).
- Inverter: Pure Sine Wave Inverter (ensures safe power for sensitive electronics like laptops and CPAP machines).
- Solar Controller: High-efficiency MPPT (Maximum Power Point Tracking) charge controller for optimal solar harvesting.
- AC-DC Charger: Dedicated smart charger for rapid topping up via shore power or a gas generator.
- Lifespan: Rated for 2,500 to 7,000 charge cycles, vastly outperforming traditional lead-acid batteries.
- Weight: The 100Ah battery weighs merely 22.6 pounds—about a third of an equivalent AGM battery.
Real-World Performance & Daily Utility
The heart of this system is the 100Ah LiFePO4 battery, and its real-world performance is fundamentally different from the heavy lead-acid batteries you might be used to. With old-school batteries, you can only safely use about 50% of the capacity before risking permanent damage. This lithium battery allows you to utilize nearly 100% of its stored power, giving you effectively double the usable runtime for your appliances.
In a typical camper van scenario, a 100Ah capacity is the golden standard for weekend warriors. It provides more than enough juice to run a 12V chest refrigerator continuously, keep your interior LED puck lights shining all night, run a roof vent fan, and charge two smartphones and a laptop without dipping into dangerous voltage levels.
The inclusion of a Pure Sine Wave inverter is a critical detail. Cheaper “modified” sine wave inverters can cause microwaves to buzz loudly, power tools to run hot, and delicate computer chargers to fail. The ExpertPower inverter produces grid-quality electricity, meaning you can plug in your expensive camera chargers or a CPAP machine with absolute confidence that the power delivery is smooth and clean.
Design & Build Quality
ExpertPower has built a strong reputation in the energy storage market, and the build quality of this kit reflects that. The battery itself is housed in a rugged, sealed ABS plastic casing. While it isn’t waterproof, it is highly resilient against the typical vibrations and bumps associated with driving a rigid suspension RV down a washboard dirt road.
The internal Battery Management System (BMS) is the unsung hero of this setup. It works silently in the background to protect your investment from the most common battery killers: overcharging, deep discharging, overloading, and short circuits. If you accidentally leave a heavy appliance running, the BMS will step in and shut the battery down before permanent cell damage occurs.
The MPPT solar charge controller features an aluminum heatsink backing to dissipate heat efficiently without the need for noisy cooling fans. It is a highly robust unit that extracts every possible watt from your solar panels, which is especially noticeable on cloudy days when every drop of power counts.
Ease of Use & Installation
The primary reason to invest in this specific bundle is to bypass the headache of component matching. When you buy these pieces individually, you often spend hours reading forum posts to figure out if your charge controller is safely calibrated for your specific lithium chemistry. Because this is a matched ecosystem, that friction is completely removed.
Installation still requires basic 12V electrical knowledge—you will need to source your own properly gauged copper wires, fuses, and crimp connectors to tie everything together safely. However, the heavy lifting of system design has been done for you. The AC charger is precisely tuned to the voltage requirements of the ExpertPower LiFePO4 cells, ensuring a fast, safe charge when you plug into a campsite pedestal.
What Makes It Stand Out?
What truly separates this kit from the competition is the sheer value of the bundled ecosystem. Sourcing an MPPT controller, a pure sine wave inverter, and a lithium-specific AC charger separately can easily eclipse the cost of the battery itself. Having them packaged together ensures you aren’t bottlenecking your premium lithium battery with subpar, generic charging components.
Furthermore, the sheer weight savings cannot be overstated. Replacing a 65-pound lead-acid battery with a 22-pound lithium unit makes maneuvering the battery into tight RV compartments or boat hulls dramatically easier on your lower back.

Who This Solar Kit Is Best For
The ExpertPower 12V 100Ah LiFePO4 Kit is the perfect starting point for van lifers, RV owners, and marine enthusiasts who want to build a reliable off-grid system without getting bogged down in electrical engineering. If you are upgrading from an old, dying lead-acid setup and want the longevity and depth-of-discharge benefits of lithium, this bundle provides the exact hardware you need.
It is also a fantastic choice for emergency home backup preparations. Mounting this system to a hand truck or a garage wall gives you a silent, fume-free alternative to a gas generator, allowing you to keep your fridge running and your phones charged during unexpected power grid failures.
Final Thoughts
Transitioning to lithium power is the single best upgrade you can make to an off-grid rig, but piecing a system together component by component can quickly turn into a frustrating puzzle. The ExpertPower LiFePO4 Kit expertly solves this problem by delivering a matched, high-performance ecosystem straight to your door.
From the safety of the built-in Battery Management System to the clean power output of the pure sine wave inverter, every piece of this bundle is geared toward reliability. While you still need to handle the physical wiring, knowing that your charge controller and inverter are perfectly dialed in for your battery provides immense peace of mind. If you are ready to cut the cord and enjoy consistent, worry-free power wherever you park, this cohesive kit is an outstanding investment.
