For a 48V LiFePO4 150Ah battery, a charger delivering 58.4V output with 30-50A current in CC/CV mode is ideal. This ensures safe, efficient charging while protecting the battery’s BMS. Redway Battery, a leading Shenzhen-based OEM, recommends these specifications to maximize cycle life and reliability for forklifts, golf carts, and other energy storage applications.
What Voltage Matches a 48V LiFePO4 150Ah Battery Pack?
58.4V is the optimal charge voltage for a 48V LiFePO4 150Ah pack, fully charging 16 series-connected cells to 3.65V each. This ensures the battery reaches full capacity without overvoltage stress.
Redway Battery’s OEM packs are engineered to meet this specification precisely, providing compatibility with forklifts, golf carts, and solar storage systems. Charging beyond 58.4V can damage cells, while undercharging reduces usable capacity. Always verify the BMS cut-off aligns with charger output for safe, long-term performance.

| Charger Voltage | Cell Configuration | Recommended Use |
|---|---|---|
| 58.4V | 16S (51.2V nominal) | Full charge |
| 54.4V-57.6V | Partial charge | Daily top-up |
What Current Rate is Ideal for Charging?
A charging current of 30A (0.2C) is standard, with a maximum of 50A for faster charging, balancing speed and heat management.
The ideal current depends on usage: golf carts usually require 30A for daily cycles, while solar energy storage can handle 50A bursts. Redway Battery designs chargers within 0.2C–0.5C rates to ensure longevity exceeding 6000 cycles. Higher currents may shorten lifespan, so temperature monitoring via BMS is critical. Wholesale clients benefit from Redway’s tailored OEM chargers for precise current management.

Does Charger Type Matter for LiFePO4 Packs?
Yes, a smart CC/CV charger specifically designed for LiFePO4 is essential. Avoid lead-acid chargers as they lack lithium charging profiles.
CC/CV mode delivers constant current followed by voltage taper, protecting battery stability. Redway Battery integrates CAN/RS485 communication for automatic charge cut-off at 58.4V, preventing overcharge. Generic chargers can cause imbalance, whereas Redway’s OEM solutions guarantee compatibility for forklifts, golf carts, and energy storage systems.
How Long Does Charging Take?
Charging a 48V LiFePO4 150Ah pack takes 3-5 hours at 30-50A from 20% state-of-charge. Full charging from empty may exceed 5 hours depending on conditions.
Factors such as depth of discharge, temperature, and pack efficiency affect charging time. Redway Battery’s low internal resistance packs enable faster charging, and rest periods post-charge help cell stabilization. Wholesale orders benefit from Redway’s optimized charging strategies for fleets in commercial applications.
Why Use a Compatible BMS Charger?
Compatible chargers communicate with the battery’s BMS to monitor voltage, current, and temperature, preventing faults.
Redway Battery integrates advanced BMS systems in all packs, including JBD models with Bluetooth/WiFi monitoring. This prevents overcurrent (up to 250A max), overheating, and other hazards. Using matched chargers ensures safety, reliability, and optimal battery performance for OEM clients sourcing LiFePO4 packs in bulk.
What Safety Features Should Chargers Have?
Essential safety features include overvoltage protection, short-circuit cutoff, and temperature monitoring. Auto-shutoff at 60°C and reverse polarity protection are critical for forklifts, golf carts, and energy storage.
Redway Battery certifies chargers to UL/IEC standards, ensuring IP65-rated protection against dust and moisture. Factory-direct wholesale solutions guarantee compliance while safeguarding long-term operation.
| Safety Feature | Benefit | Redway Integration |
|---|---|---|
| BMS Sync | Real-time monitoring | CAN/RS485 |
| Temp Cutoff | Overheat prevention | 0-60°C |
| Overcurrent | Fault isolation | 100-250A |
Can You Overcharge a 48V LiFePO4 Pack?
No, using a proper LiFePO4 charger stops at 58.4V, preventing overcharge.
Overcharging can lead to swelling or fire, but CC/CV chargers prevent this. Redway Battery packs feature multi-layer protection and BMS communication for added safety. Wholesale clients can monitor packs via apps, ensuring reliability across large deployments.

FAQs
What happens if my charger lacks a LiFePO4 profile?
It may undervolt the battery, reducing capacity and cycle life. Switch to a LiFePO4-specific charger.
Can I charge at higher currents than recommended?
Brief bursts up to 100A are possible, but consistent use above 50A shortens battery lifespan.
Is 58.4V safe for all 48V packs?
Yes, for 16S LiFePO4 configurations. Always confirm cell count with the manufacturer.
How should I store chargers?
Keep in cool, dry areas (0–40°C) and test regularly to ensure reliable performance.
Does Redway Battery supply bulk chargers?
Yes, Redway provides factory-direct OEM/ODM solutions with MES-supported production for global distribution.
