Product Description

Introducing the versatile 12V400Ah Lithium Battery, expertly engineered for Trailer, Camper, Boat, and RV applications. Experience unparalleled power and longevity with our cutting-edge technology.

The 12V lithium-ion battery pack is designed to excel in three primary applications:

1. High-Capacity Power Supply: This application focuses on providing substantial electric power for trailers, camper vans, motor homes, and boats, ensuring a reliable energy source for your adventures.

2. Lead Acid Battery Replacement: Perfect as a modern substitute for traditional lead-acid batteries in vehicles like electric tricycles, low-speed electric cars/trucks, golf carts, sanitation trucks, sweepers, scrubbers, and armgates.

3. Renewable Energy Storage: Ideal for storing electricity generated from solar panels or windmills, offering an efficient and eco-friendly energy solution.

High Energy Density and Light Weight: Compared to lead-acid batteries, our 12V lithium batteries are significantly more compact and offer deeper discharge capabilities. This results in the storage of more electrical energy within a smaller and lighter unit, which is perfect for trailer campers, boats, and other electric vehicles, extending their range and power supply duration.

Long Cycle Life: Our lithium batteries boast an impressive long cycle life, capable of handling over 4000 charge and discharge cycles without significant performance degradation. This durability is crucial for trailers, campers, RVs, and boats used over long periods and frequently recharged.

Fast Charging Capability: These lithium batteries support rapid charging speeds, which is particularly beneficial for quickly recharging trailers and boats while docked. This minimizes downtime and maximizes the efficiency of your electric vehicles.

Intelligent Management System: Equipped with advanced intelligent battery management systems, our batteries can monitor their status, optimize charging and discharging processes, and offer remote monitoring and management. This ensures safe operation, extends battery life, and enhances overall system performance.

High Adaptability: Due to their lightweight and compact design, these 12V batteries with small to medium capacities can flexibly replace most lead-acid batteries, providing a versatile power solution.

We manufacture energy storage battery packs in various capacities, including 12V50Ah, 12V80Ah, 12V100Ah, 12V150Ah, 12V200Ah, 12V300Ah, 12V400Ah, and 12V500Ah. These packs can also be combined in parallel and series to meet diverse energy needs.

FAQ

What is the regular lead time after I place my order?
We are a dedicated factory specializing in make-to-order products. Typically, sample orders take around 15-20 days to process, while batch orders require approximately 25-30 days, depending on order quantities and capacities. We can expedite lead times if necessary.

What are your trade terms and payment terms?
We welcome most standard trade terms, including EXW, FOB, CIF, and DDU.
We generally require a minimum of 30% advance payment to begin your order, with the remaining 70% due upon your acceptance of the finished products and prior to delivery. Irrevocable L/C at sight is also accepted.

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

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

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

Can your batteries be used in series?
Most of our batteries are not designed to be used separately. However, we offer 12V small battery modules that can be used in series or parallel configurations to replace old lead-acid batteries. Please inquire in advance.

Do your batteries have a thermal management system?
Most of our batteries feature a thermal management system controlled by the BMS (Battery Management System). This system prevents battery usage if the temperature is too high or too low. Please inquire in advance.

Do you provide OEM or ODM?
Yes, we offer both OEM and ODM services.

How many years will your battery last?
Lithium Iron Phosphate (LiFePO4) batteries can be cycled between 2000 and 5000 times. With daily cycling and an 80% Depth of Discharge (DoD), you can expect 5 to 10 years of battery life.

How do I install your batteries?
All of our batteries come with free ring terminals for easy connection to your inverter, cart, or busbar system.

Can I leave your batteries outside?
No. Our batteries are not marine-rated or weatherproof. Exposure to sun or rain can damage the batteries, and such damage is not covered under warranty.
