SUPER EMPOWER 12V 100Ah LiFePO4 Battery – Compact Group 24 Drop-In

The SUPER EMPOWER 12V 100Ah LiFePO4 battery is a straightforward drop-in replacement for your RV’s existing Group 24 lead-acid battery. It weighs just 21.6 pounds—about half of what you’d expect from an equivalent AGM—and fits perfectly into standard battery boxes without any modifications. The integrated 100A BMS protects against overcharge, over-discharge, overcurrent, and short circuits, giving you peace of mind while you’re on the road.

One standout feature is its cycle life: you can expect up to 5,000 cycles at 100% depth of discharge, and an impressive 15,000 cycles at 60% DOD. That means this battery could easily serve you for over a decade if you treat it well. Charging is straightforward with a dedicated LiFePO4 charger, solar panels set to lithium mode, or a DC-DC charger. Just remember that charging is disabled below 32°F (0°C) due to low-temperature protection, so keep that in mind if you camp in cold climates.

GRNOE 2-Pack 12V 100Ah LiFePO4 Batteries – Expandable DIY System

The GRNOE 2-pack offers two 12V 100Ah lithium batteries weighing just 21.9 pounds each—50% lighter than lead-acid. They fit BCI Group 24 battery boxes, making them a simple drop-in for most RVs. Each battery has its own 100A BMS with dustproof, moisture-proof, and salt-spray resistance for durability in tough environments. What sets GRNOE apart is the expandability: you can connect up to 4 in series and 4 in parallel to build a 51.2V 400Ah system (20.48kWh) for serious off-grid setups.

The cycle life is rated at up to 15,000 cycles at 60% DOD, which translates to over 10 years of daily use. The BMS protects against overcharge, over-discharge, overcurrent, overvoltage, and short circuits. Starting with this 2-pack gives you 200Ah of capacity right away, and you can add more batteries later as your energy needs grow. It’s an ideal entry point for DIY solar systems, RV off-grid builds, or marine applications where you want room to expand without replacing equipment.

• 【2× POWER, 15,000 CYCLES – LASTS 10X LONGER】 Double your capacity with two Grade A+ LiFePO4 batteries. Each 12.8V 100Ah unit offers up to 15,000 cycles @60% DOD — 10X longer lifespan than lead-acid. That’s over 10 years of reliable, maintenance-free energy for RVs, boats, solar homes, and more.
• 【DUAL 100A SMART BMS & FULL SAFETY PROTECTION】 Each battery includes a 100A BMS that protects against overcharge, over-discharge, overcurrent, overvoltage, and short circuit. Plus, with dustproof, moisture-proof, and salt-spray resistance, they’re built to perform in tough and wet conditions.
• 【FLEXIBLE 4S4P EXPANSION – BUILD UP TO 20.48kWh】 Start with two, expand up to 4 in series and 4 in parallel for 51.2V 400Ah (20.48kWh). Great for growing power needs—whether it’s for off-grid living, backup systems, or energy-hungry devices.
• 【LIGHTWEIGHT & GROUP 24 SIZE – EASY DROP-IN】 Each battery weighs just 21.9 lb—50% lighter than lead-acid—and fits BCI Group 24 battery boxes. Easy to install in RVs, campers, boats, and any space-limited setup.
• 【MULTI-PURPOSE ENERGY – RUNS EVERYTHING YOU NEED】 Use the pair across solar setups, trolling motors, marine systems, RVs, travel trailers, emergency backup, and DIY power builds. Power a CPAP up to 84h, a fridge for 34h, or light up your off-grid cabin with confidence.
• 【Certified Safety, Smart Use Tips & 5-Year Peace of Mind】 Certified by UN38.3, IEC, CE, UL, and RoHS for top-level safety and reliability. Important reminders: · Not for engine starting or high-current surge applications · Do not submerge the battery in water · Avoid overloading beyond rated capacity Now upgraded with a 5-year warranty and 10-year repair service — feel free to contact us directly via Amazon if you have any issues.
• 【First Use & Charging Notice】 1.To protect battery health, some units may ship in 0V protection mode. Use a 14.6V LiFePO₄ activation charger to wake it up before charging (e.g., 14.6V 8A charger with 0V function). 2.Avoid using 12V chargers, standard lead-acid chargers, or automotive chargers. Chargers with repair, pulse, or desulfation modes designed for lead-acid batteries may interfere with the LiFePO₄ BMS and trigger early protection shutdown.
• 3.Before connecting batteries in series, ensure each battery is fully charged and the voltage difference does not exceed 0.2V (fully charged ≥14V). 4.To maintain battery health, charge at least once every 2–3 months if not in use. 5.When connecting multiple batteries, use the same model and age; for best balance, fully charge each battery individually before series connection. ✅ Using a LiFePO₄-compatible charger helps extend battery life and ensures reliable, safe performance.

Buyer’s Guide: What to Consider

Choosing the right lithium battery for your RV can feel overwhelming with so many options. Here are the key factors to consider before you buy—they’ll help you match a battery to your specific camping style, power needs, and budget.

• Capacity (Ah) and Your Energy Needs: Amp-hours (Ah) tells you how much energy the battery can store. For a small RV with basic lights and a fridge, 100Ah might be enough. For running air conditioners or multiple days off-grid, look at 200Ah or more. Calculate your daily watt-hour usage and divide by 12V to get the minimum Ah you need.
• Battery Management System (BMS): A good BMS protects against overcharging, deep discharging, overcurrent, and temperature extremes. A 100A BMS is standard for most 100Ah batteries, but if you plan to run high-draw appliances, look for a 200A or 300A BMS. Some advanced BMS units also offer cell balancing and low-temperature cut-off.
• Temperature Protection and Self-Heating: Lithium batteries can be damaged if charged below freezing. Many batteries include low-temperature charging protection that stops charging below 32°F. If you camp in cold climates, consider a battery with self-heating technology, which warms the cells before allowing charging, so you can use it year-round.
• Weight and Size (Form Factor): Lithium batteries are typically 50-70% lighter than lead-acid. Look for Group 24, Group 31, or custom sizes that fit your battery box. Lighter batteries are easier to install and reduce overall RV weight, saving fuel. Compact models also free up space for other gear.
• Cycle Life and Longevity: Cycle life is the number of charge/discharge cycles before capacity degrades significantly. High-quality LiFePO4 cells can deliver 4,000 to 15,000 cycles depending on depth of discharge. A battery rated for 5,000 cycles at 100% DOD will last over a decade with daily use. Lower DOD (e.g., 60%) extends cycle life dramatically.
• Expandability (Series/Parallel Connections): Most 12V lithium batteries can be connected in series (to increase voltage) or parallel (to increase capacity). If you plan to expand your system later, choose a battery that supports up to 4 in series and 4 in parallel. This gives you flexibility to grow from 12V to 48V or from 100Ah to 400Ah without buying all-new components.
• Smart Features (Bluetooth and App Monitoring): Built-in Bluetooth lets you check battery voltage, current, temperature, and state of charge from your phone. This is handy when the battery is tucked away in a compartment. Some apps also send alerts for abnormal conditions. If you like to track your power usage, look for a battery with a companion app.

Conclusion

Upgrading to lithium is one of the best investments you can make for your RV. You’ll enjoy lighter weight, faster charging, longer cycle life, and more usable capacity compared to lead-acid. Whether you’re a weekend boondocker or a full-time traveler, there’s a lithium battery that fits your setup perfectly.

For most RVers, the SUPER EMPOWER 2-pack offers unbeatable value for a dual-battery bank, while the VATRER POWER 460Ah with self-heating is the top choice for cold-weather adventurers.
