12V LiFePO4 Lithium Batteries

12 volt lithium batteries are an excellent choice for powering RVs, off-grid systems, trolling motors, and various marine applications.  Their lightweight design and high energy density make them far superior to traditional lead-acid batteries, providing more power with less weight. This is particularly beneficial for RV enthusiasts looking to maximize storage space while maintaining efficiency.

Explore LiTime 12V Lithium Battery Capacities and Series

12V Lithium Batteries are the most common and fundamental configuration among Lithium Batteries, providing a versatile solution for a wide range of energy needs. LiTime 12V lithium batteries cover a broad capacity range from 6Ah to 560Ah, providing options for virtually any 12V application.

The lineup includes standard, Smart, ComFlex, Self-Heating, Xtra-Mini, Slim, TM, OBM, and Group series, designed to meet specific performance requirements.

  • 12V Small-capacity batteries (6–50Ah) are ideal for portable applications, RVs, trolling motors, and marine starting, including dedicated starting batteries.
  • 12V Mid-capacity batteries (65–200Ah) suit standard RV setups, off-grid solar systems, and light industrial equipment, often as deep-cycle units or dual-purpose batteries.
  • 12V High-capacity batteries (230–560Ah) are designed for larger off-grid solar installations, commercial, or industrial backup power, providing robust deep-cycle performance.

Smart and ComFlex models provide integrated monitoring and modular flexibility, while Self-Heating and Low-Temp variants ensure reliable operation in colder conditions.

Dual-purpose and high-capacity deep-cycle batteries allow users to select the best 12V battery for their specific energy needs, balancing starting power, continuous discharge, size, and specialized features.

System Integration and Flexible 12V Configurations

For optimal performance, LiTime 12V batteries work seamlessly with 12V LiFePO4 Battery Chargerssolar charge controllers, and compatible BMS units. These accessories ensure stable energy conversion, efficient charging cycles, and long-term battery safety for all types of 12V systems.

Users can create custom 12V lithium battery banks by connecting multiple units in series or parallel. Series connections allow you to increase system voltage to 24V, 36V, or 48V for higher-voltage applications, while parallel connections, such as connecting multiple 100Ah batteries, increase total capacity for extended runtime. Proper balancing and BMS support are essential to ensure safe operation and optimal performance.

This combination of versatile capacities, series options, and compatible accessories makes LiTime 12V lithium batteries ideal for RV power systems, trolling motors, marine starting applications, off-grid solar installations, and industrial backup power. Explore our full lineup to find the perfect 12V lithium battery solution for your application.
