Custom 48V Lithium Battery Manufacturer

In medium-to-high power industrial and power-driven equipment, 48V is commonly used as a core power platform to support higher loads, longer runtime, and more complex operating environments. As electrification and automation advance, higher requirements are placed on continuous output capability and system stability.
LARGE specializes in custom 48V lithium battery development, providing integrated solutions from cell matching and structural design to BMS system integration. Each system is engineered based on load characteristics and operating environments to ensure stable and reliable performance under high load, frequent start-stop, and wide temperature conditions.

48V Lithium Battery Engineering Capabilities

LARGE provides full-process services from concept to mass production:

  • Load profile matching (continuous/peak current, startup surge)
  • Mechanical design (anti-vibration, waterproofing, thermal dissipation or heating)
  • Smart BMS development (communication protocols, protection thresholds, balancing strategy)
  • Prototyping, validation testing, and mass production delivery
  • Certification support (UL / CE / CB / UN38.3, etc.)
  • Reliability testing (vibration, thermal cycling, and safety validation)

48V Lithium ion Battery FAQs

Can 48V lithium batteries be customized?

Yes, they can be customized in capacity, structure, discharge rate, BMS functions, and communication protocols based on application needs.

Thermal management is controlled through BMS monitoring, temperature sensors, and optional cooling or heating designs to prevent overheating and ensure safe operation.

Yes, most 48V golf carts can be upgraded to lithium batteries, but the BMS, charger, and discharge compatibility must be properly matched.

Typically 500–1500 cycles depending on chemistry and usage, which equals about 3–8 years in normal industrial applications.

Usually 13S for NMC/NCA (48V nominal) or 16S for LiFePO4 (51.2V nominal), depending on battery chemistry.

The price varies based on capacity, BMS, and customization requirements. Higher capacity and industrial-grade systems cost significantly more.

Lithium batteries should not be jump-started like lead-acid systems. If protection is triggered, the BMS must be reset or reactivated safely.
