The 48V ETPG48 481 1 50 forklift charger is a high-performance charging solution optimized for industrial applications. It supports 48V lithium and lead-acid batteries with adaptive current output (up to 50A peak) and employs smart CC-CV charging algorithms to prevent overcharging. Thermal management systems ensure stable operation at 25–40°C, while IP54-rated housing provides dust/water resistance for harsh warehouse environments.
How Much Do Different Forklift Batteries Weigh by Type?
What voltage range does this charger support?
Specialized for 48V battery systems, the ETPG48 operates at 42–58V input with ±1% voltage precision. It automatically adjusts for 14-cell LiFePO4 (44.8–58.8V) or 24-cell lead-acid (48V nominal) configurations.

The charger employs active voltage compensation to maintain stability during grid fluctuations. For lithium batteries, it terminates at 58.8V ±0.5V, while lead-acid profiles taper at 57.6V. Pro Tip: Use digital multimeters monthly to verify output—drifts >2% indicate required calibration.
How does thermal management work?
Dual temperature-controlled fans and aluminum heatsinks maintain components below 85°C. At 40°C ambient, it reduces current by 25% to prevent overheating—critical for multi-shift operations charging 500–800Ah battery banks daily.

Internally, NTC sensors monitor MOSFET and transformer temps every 15 seconds. A three-stage cooling protocol activates: 1) Fan speed increase (60°C), 2) Current throttling (75°C), 3) Emergency shutdown (90°C). Example: In a 35°C warehouse, 50A charging automatically drops to 38A after 90 minutes of continuous use.
| Thermal Stage | Action | Recovery Time |
|---|---|---|
| 60–75°C | Forced Air Cooling | Immediate |
| 75–90°C | Current Reduction | 15–30 mins |
What safety certifications does it have?
Certified to UL 1564 and IEC 60335-2-29 standards with 12 protective features including reverse polarity detection, short-circuit resilience (withstands 200A surges for 50ms), and isolation resistance >100MΩ.

FAQs
Yes, selectable AGM mode applies 14.4V/cell absorption with 3-hour float stage—avoid using lithium profiles on lead-acid as it causes sulfation.
What’s the warranty period?
3-year limited warranty covering power modules and control boards, excluding physical/water damage. Pro Tip: Register serial numbers online for expedited service claims.
