What is a 48V Lithium Battery?
A 48V lithium battery is a rechargeable power source that delivers 48 volts of electricity. It’s commonly built with LiFePO4 (Lithium Iron Phosphate) chemistry, known for its stability, safety, and long cycle life.
Unlike lead-acid batteries, which are heavy and degrade quickly, 48V lithium batteries are lightweight, fast-charging, and highly efficient.

Common Uses of 48V Lithium Batteries
- Golf Carts – smoother rides with longer runtime
- Solar Storage Systems – dependable renewable energy backup
- Electric Vehicles (EVs & E-bikes) – sustainable, high-power mobility
- Industrial Use – forklifts, pallet jacks, and server rack batteries
- Home Energy Backup – UPS and off-grid storage
Why Choose a 48V energy storage solution ?
Here’s why 48V lithium is replacing outdated battery types:
- Higher Efficiency – Delivers consistent voltage without performance drop.
- Lightweight Design – Easier to transport and install compared to lead-acid.
- Longer Lifespan – Up to 5x more cycles than traditional batteries.
- Fast Charging – Charges in a fraction of the time.
- Low Maintenance – No need for water refilling or acid checks.
Sisway Battery’s 48V solutions are built with advanced BMS (Battery Management System) for maximum safety and performance.
Battery Lifespan: What to Expect from 48V Systems
- Cycle Life: 2000–5000 charge cycles (5–10 years depending on usage)
- Lead-Acid Comparison: Only 300–500 cycles (2–3 years)
- Factors Affecting Longevity:
- (1) Charging practices
- (2) Operating temperature
- (3) Depth of discharge
A well-maintained Sisway 48V lithium battery can last up to a decade, making it a cost-effective investment.
Charging Your 48V System
- Charging Time: Typically, 3–5 hours for a full charge
- Best Practice: Use a lithium-compatible charger with BMS support
- Safety Tips:
- (1) Avoid overcharging
- (2) Charge at room temperature
- (3) Use manufacturer-recommended chargers
How Much Does a 48V Lithium Battery Cost?
The price depends on capacity (Ah) and application:
- Golf Cart Batteries (48V, 100Ah–200Ah): $900 – $2,000
- Solar Storage (48V rack batteries): $1,200 – $4,000
- Industrial (forklifts, pallet jacks): $2,500+
While upfront costs are higher than lead-acid, the total cost of ownership (TCO) is lower due to longer lifespan and reduced maintenance.
Key Features to Look for in a 48V LiFePO4 pack
Before buying, check for:
- Battery Capacity (Ah rating) – Determines runtime
- Built-in BMS – Protects against overcharge, discharge, and short circuit
- Warranty – At least 3–5 years for reliable performance
- Certifications – UL, CE, ISO for safety compliance
Sisway Battery offers certified 48V lithium batteries with strong warranties and long-lasting performance.
