CTS 666V 240Ah LiFePO4 Battery for Electric Bus, High Voltage EV Power Battery

Product Description

Bus LiFePO4 Battery | High-Voltage Propulsion for Electric Buses and Coaches

The global shift toward green public transportation and zero-emission fleets is accelerating the adoption of electric and hybrid propulsion systems for city buses, coaches, and commercial passenger vehicles. Today, a growing number of bus applications — including city buses, intercity coaches, shuttle buses, tour buses, and work buses — are transitioning to cleaner, quieter, and more efficient lithium battery power. With advanced automotive-grade engineering and strong OEM capabilities, CTS Battery provides customized high-voltage lithium battery solutions tailored to the specific energy and space requirements of each bus.

Our solutions are designed to deliver:

• Reliable propulsion power for long-distance routes

• High energy density with reduced weight

• Safe operation in harsh road and weather conditions

• Seamless integration with hybrid or fully electric drive systems

Whether you are building a new electric bus or upgrading an existing fleet to electric power, CTS helps you build a safe, high-performance, and future-ready bus power system.

The Advantages of Bus LiFePO4 Battery

Built for Harsh Road Environments

Buses face road vibration, dust, humidity, and long operating hours. Our high-voltage battery pack is engineered with IP67 waterproof and dustproof housing, stainless steel enclosure, and vibration-resistant construction to withstand the toughest conditions on the road.

Lightweight & High Energy Density

Up to 50% lighter than traditional lead-acid batteries, significantly improving vehicle efficiency and payload capacity. The 240Ah capacity provides extended driving range, while the compact modular design saves valuable onboard space.

Smart BMS with Advanced Protection

Built-in intelligent Battery Management System ensures:

• Overcharge / over-discharge protection

• Cell balancing and temperature control

• Short circuit and overcurrent protection

• Real-time SOC monitoring via CAN / RS485

Flexible Customization for Your Bus

We understand that every bus has unique power requirements. That's why we offer:

• Voltage options: 600V / 666V and custom

• Capacity customization: 200Ah — 300Ah

• Liquid cooling (standard) and liquid heating (optional)

• CAN / RS485 communication protocols

• IP67 / higher IP ratings upon request

• Size and structure tailored to bus layout

Seamless Integration with Hybrid/Electric Propulsion

The high-voltage system supports fast charging (up to 120kW CCS2) and integrates easily with bus inverters, motors, and energy management systems — perfect for both new builds and retrofits.
