Automotive-Grade Cells

Utilize our made LiFePO4 battery cell are Automotive -Grade, ensure superior quality and higher energy density, supporting 100% Depth of Discharge (DOD) and 100% State of Charge (SOC).

Long Lifespan and High Efficiency

Lithium Marine Battery are maintenance-free and cost-effective in the long run, boasting longer lifespans and higher efficiency.

Lightweight Design

Lithium battery packs are about two-thirds the size and one-third the weight of lead-acid batteries, making them easier to carry and perfect for outdoor camping and indoor installations.

Built-in Battery Management System (BMS)

LFP batteries have a significantly longer lifespan compared to lead-acid batteries. While lead-acid batteries typically last around 3-5 years, LFP batteries can last 10 years or more, depending on usage and maintenance.

Flexible Configuration (Max 4S4P)

Supports flexible series and parallel configurations, up to 4S4P, providing up to 40.96 kWh of energy.

Environmental Benefits

Unlike lead-acid batteries, which contain hazardous lead and can pollute if not disposed of properly, lithium batteries are produced in an eco-friendly manner without harmful emissions.
