Product Description

12V400Ah Lithium Battery for Trailer, Camper, Boat, and RV

The 12V lithium-ion battery pack serves three major applications:

For the first application, the battery is typically of large capacity, ideal for supplying electric power in trailers, camper vans, motor homes, boats, and more. This high capacity ensures reliable and sustained power supply for extended journeys.

For the second application, the battery replaces conventional lead-acid batteries in various electric vehicles such as electric tricycles, low-speed cars/trucks, golf carts, sanitation trucks, sweepers, scrubbers, arm gates, and more. This substitution enhances performance, longevity, and efficiency.

For the third application, the battery is used for storing energy generated by solar panels or wind turbines, offering a sustainable and efficient solution for renewable energy storage.

High Energy Density and Light Weight: Compared to lead-acid batteries, 12V lithium batteries are significantly more compact and have deeper discharge capabilities. They can store more electrical energy within a smaller, lighter package. For trailer campers, trailers, boats, and other electric vehicles, this means they can provide sufficient power for a longer range or extended power supply time.

Long Cycle Life: Lithium batteries are renowned for their long cycle life, capable of enduring over 4000 charge and discharge cycles with minimal performance degradation. This durability is crucial for trailers, campers, RVs, and boats that are used extensively and frequently recharged.

Fast Charging Capability: Lithium batteries support fast charging speeds, making them ideal for quickly recharging trailers and boats while docked. This feature minimizes downtime and enhances the operational efficiency of boats and trailers.

Intelligent Management System: These batteries come equipped with advanced battery management systems that monitor battery status, optimize charging and discharging processes, and offer remote monitoring and management capabilities. This ensures safe operation, extends battery life, and enhances overall system performance.

Highly Adaptable: Thanks to their light weight and compact size, these 12V batteries with small to medium capacities can flexibly replace most lead-acid batteries, providing a versatile and efficient power solution.

We produce a variety of energy storage battery packs with different capacities. Available options include 12V50Ah, 12V80Ah, 12V100Ah, 12V150Ah, 12V200Ah, 12V300Ah, 12V400Ah, and 12V500Ah. These batteries can also be used in parallel or series configurations for even greater flexibility and power.

What shipping methods do you offer?
Given that lithium-ion batteries are classified as Class 9 Dangerous Goods, we strongly recommend shipping all batteries by sea freight.

Do you offer a warranty, and if so, for how long?
Yes, we provide a three-year warranty for all our battery packs. However, buyers can request an extended warranty period before placing orders. Please inquire about the 'Terms and Conditions Of the Warranty' before ordering.

What are the application fields of your battery packs?
Our Li-ion battery packs cater to a wide range of applications, including electric vehicles (4-wheeled and 3-wheeled trucks, sweepers, cars, forklifts, golf carts, sight-seeing buses, monorails, ATVs, UTVs, tricycles, motorcycles, toy cars, etc.), solar energy storage, electric equipment (floor scrubbers, lifting platforms, small excavators, tractors, pallet stackers, grass cutters, small cranes, garbage tanks, arm gates, etc.), outdoor portable power supplies, construction equipment power supply, streetlight power packs, boat power packs, camper power packs, and more.
As a customization-oriented Li-ion battery manufacturer, we welcome customizations for various applications.
