CTS 400V 50Ah NMC Waterproof Lithium Battery System with BMS and Liquid Cooling for Electric Car Manufacture

Headquartered in Hunan, China, CTS specializes in customized high-voltage NMC lithium batteries, delivering complete power battery solutions for electric vehicles, construction machinery, AGV robots and electric marine equipment. Our standard 400V 50Ah NMC battery pack supports full customization on voltage, capacity and dimensions for new energy vehicle assembly and fuel-to-electric conversion projects. Equipped with brand-new Grade A NMC cells, vehicle-grade smart BMS, standard liquid cooling pipeline design, optional winter heating system, active balance and remote cloud monitoring. We provide one-stop OEM & ODM services, and all battery packs can be supplied with complete automotive safety certifications.

High-quality brand-new Grade A NMC cells with outstanding energy density and stable high-power output. Great cycle performance with a 10-year design lifespan for vehicles. Consistent driving range, much lower replacement cost compared with lead-acid batteries. Every single cell comes with traceable QR code for full quality tracking.

Self-developed battery management system for vehicle applications. Passive balance is standard, while active balance is available for upgrade. Compatible with CAN/RS485 communication protocols. Multiple protection functions including overcharge, overdischarge, overcurrent, short circuit, over-temperature and thermal runaway, fully meeting global automotive safety standards to monitor every cell string precisely.

Comes with built-in liquid cooling pipelines. Optional air cooling, PI film heating and silicone film heating components. Automatic preheating under low temperatures and intelligent heat dissipation at high loads. Ensures consistent power delivery under all climate conditions worldwide.

Integrated metal housing with reliable sealing structure. Equipped with MSD manual service disconnect and explosion-proof valve. Pre-drilled mounting holes support direct chassis installation without massive frame modification. Resists road impact, moisture and dust, ideal for off-road vehicles and construction machinery under harsh working conditions.

CAN / RS485 communication ports are reserved to connect with vehicle central control panels. Real-time data including SOC, cell voltage, temperature and fault codes can be displayed. Cloud remote monitoring is supported to simplify equipment operation maintenance and after-sales service.

Voltage, capacity, dimensions, high-voltage connectors and communication protocols can be customized on demand. Optional fast charging kits, Bluetooth monitoring APP and GPS anti-theft modules, compatible with mainstream global charging standards. Suitable for passenger cars, off-road UTV/ATV, construction machinery, AGVs, electric boats and special electric equipment.

Lightweight structure optimized via CAE (Computer Aided Engineering) simulation to improve the energy density of battery systems. Standard cell modules support high-voltage platforms ranging from 200V to 1000V, helping vehicle and equipment manufacturers shorten new product development cycles and accelerate project implementation.

We cooperate with professional power battery labs to conduct full reliability tests, including temperature cycling, vibration, water spray, dust resistance, EMC electromagnetic compatibility and abuse safety tests. Every battery pack undergoes aging testing before delivery to guarantee long-term operational stability.

Free of heavy metals and corrosive electrolyte. Zero daily maintenance and zero emissions during operation. Compliant with global new energy environmental regulations, helping equipment manufacturers cut compliance costs and realize electrification upgrading from fuel-powered machinery.
