Tired of running out of power quickly in your compact RV or off-grid cabin? It’s time to upgrade and say goodbye to capacity anxiety. Redodo, a leading lithium iron phosphate (LiFePO4) battery brand focusing on outdoor energy solutions, launches its latest innovation——the Redodo 12V 165Ah Bluetooth LiFePO4 Battery, which is designed for users who need more capacity in small RVs and limited space.

The high-performance battery delivers an impressive 165Ah of capacity within the compact Group 31 size. On the other hand, this battery offers 2112W high power, making it one of the highest-performing Group 31 batteries on the market in both capacity and output power.

Max. 165Ah Capacity in Group 31 Size

Breaking the boundaries of traditional Group 31 batteries, the Redodo 12V 165Ah Group 31 LiFePO4 battery delivers 65% more capacity without increasing size. This innovation provides extra 65% longer runtime for appliances, setting a new standard for capacity in the Group 31 category.

2112W Market-Leading High Power

Engineered for demanding applications, the 12V 165Ah lithium battery ensures stable and efficient energy output. Compared to other 12V high-capacity batteries equipped with 120A-150A BMS, the Redodo’s battery features an industry-leading 165A BMS to reach a 2112W high power, effortlessly handling high-power loads like air conditioners, microwaves, and coffee makers. 

Additionally, the upgraded BMS can support up to 20+ protections against overcharge, over-discharge, over-current, short circuit, high & low-temp. The extra auto-recovery after overload protection in 30s, salt-spray resistance, and moisture-proof ensure all-round safety in harsh outdoor environments.

Smart Bluetooth Monitoring

With built-in Bluetooth 5.0 technology, the smart battery allows users to track voltage, capacity, state of charge (SOC), and charge/discharge status in real-time through their mobile phone. No more guessing and capacity anxiety—monitor your battery’s health and power levels remotely, and enjoy stress-free power management wherever you are.

Customized Structural Design

Whether in its internal components or external structure, this battery consistently maintains robust and reliable performance. Constructed with automotive-grade prismatic LiFePO4 cells, this 165Ah Group 31 battery features customized metal structure design for enhanced heat dissipation and cell fixation, preventing thermal expansion and ensuring stable performance under heavy loads. Additionally, the IP65-rated casing offers superior protection against water, dust for marine and outdoor conditions. 

One Pack Replaces 3*12V 100Ah Lead-Acid

At a 1C discharge rate, the 12V 165Ah LiFePO4 battery provides more energy as three 12V 100Ah lead-acid batteries, yet it is significantly lighter, more compact, and has a more consistent discharge performance.

• Drop-in Group 31 battery replacement—measuring 13 x 6.77 x 8.5 inches (330 x 172 x 216 mm) of the standard Group 31 dimensions, easy to fit into a wide range of RVs battery compartments.

• 82% lighter—eliminating excess weight for better fuel efficiency in RVs and boats.

• Saving 66% space—freeing up valuable storage in scenes where space is limited.

• Zero maintenance—more eco-friendly and sustainable energy, no environmental pollution, no more dealing with water refills, acid leaks, or corrosion.

• Longer lifespan—the cycle life is 3 times longer than lead-acid alternatives, with up to 15,000 cycles and 10-years lifespan.

Fast Charging in 4.2 Hours 

Unlike lead-acid batteries that require up to 10 hours to recharge, the Redodo 12V 165Ah lithium battery supports ultra-fast charging in just 4.2 hours when paired with Redodo 12V 40A LiFePO4 charger. The rapid charging ensures continuous power for longer trips. It can also be charged by solar panels, alternators, and generators for flexible power supply.

Smarter Choice than 200Ah Battery Models

While slightly lower in capacity than a 200Ah lithium battery, the 165Ah model is 48% smaller, 26% lighter, and 16% more affordable. By optimizing energy density and weight distribution, it provides a cost-effective alternative without compromising performance. It is ideal for space-conscious users seeking high-capacity energy storage at a more accessible price point.

Long-Lasting Power in Compact RVs & Off-Grid Cabins

Designed with limited space in mind, this battery fits perfectly into compact RV battery compartments and off-grid cabins where every inch counts. Despite its Group 31 size, it delivers a massive 165Ah capacity and 2112Wh of continuous energy, maximizing energy storage without sacrificing space.

This high energy density battery unlocks more freedom in tight spaces, so you can focus on what matters most—exploring farther, staying longer, and enjoying every moment before your next recharge.
