Power your off-grid adventures, home backup systems, or RV setup with our Big Battery 12V collection, featuring rugged and reliable LiFePO₄ batteries from Rich Solar. Available in 100Ah and 200Ah capacities, these batteries offer a powerful combination of long lifespan, high efficiency, and safe, maintenance-free performance.
Whether you're running 12V lights and appliances, charging electronics, or building a full off-grid system, these deep cycle lithium batteries are built to deliver consistent power you can count on.
12V battery systems are the most common configuration for off-grid and mobile solar setups, thanks to their compatibility with RV appliances, marine systems, 12V inverters, and solar charge controllers. Lithium batteries take 12V systems to the next level by offering:
Higher usable capacity (deep discharges without damage)
Longer lifespan (up to 10X more cycles than lead-acid)
Lightweight and compact design
Faster charging and higher efficiency
Built-in safety features via integrated BMS
Whether you're upgrading from lead-acid or starting fresh, 12V lithium batteries from Rich Solar provide an ideal foundation for efficient and scalable energy storage.
The Rich Solar 100Ah 12V battery is a compact yet powerful energy storage solution ideal for smaller systems. It stores 1.28kWh of usable energy, perfect for powering basic appliances, lighting, and 12V electronics in RVs, boats, or tiny homes.
Capacity: 12.8V x 100Ah = 1,280Wh
Battery Chemistry: LiFePO₄ (Lithium Iron Phosphate)
Cycle Life: 4,000-6,000 cycles at 80% DOD
Weight: Approx. 25 lbs
Integrated Smart BMS for safety and performance
Maintenance-free and easy to install
Ideal for RVs, boats, backup power, and mobile solar setups
It’s a great choice for users who need reliable, daily-use power without adding much weight or space to their system.
Need more storage for longer runtimes or larger loads? The Rich Solar 200Ah 12V battery provides 2.56kWh of energy, making it ideal for powering refrigerators, power tools, fans, lights, and even small inverters for AC loads. With the same rugged build and LiFePO₄ chemistry as the 100Ah model, it offers greater autonomy and runtime for your system.
Capacity: 12.8V x 200Ah = 2,560Wh
Battery Chemistry: LiFePO₄
Long cycle life: 4,000-6,000 cycles at 80% depth of discharge
Built-in BMS with protections against overcharge, discharge, and short circuits
Heavy-duty casing for off-road or mobile use
Ideal for off-grid cabins, RV systems, solar trailers, and emergency power banks
The 200Ah model is great for users looking for high-capacity storage without stepping up to a 24V or 48V system.
RVs, camper vans, and trailers
Tiny homes and off-grid cabins
Boat and marine power systems
Solar-powered tool sheds, pumps, or lighting
Emergency power backup for small home loads
These batteries are especially valuable in setups that require lightweight, compact, and high-capacity storage without sacrificing reliability or safety.
