Product Overview
This stackable 20kWh lithium iron phosphate energy storage battery pack adopts premium aluminum-shell cells and optimized series-parallel architecture. It delivers dependable, long-cycle power output to meet high-energy demands across diverse use cases. Designed for home solar storage, off-grid power infrastructure, industrial emergency backup and heavy-duty outdoor machinery, this battery outperforms older battery types with reduced idle power draw, robust structural stability and accurate state-of-charge readouts. It reliably handles routine electricity supply and emergency energy reserve tasks.
Core Advantages
Industrial Grade A Aluminum Shell Cells
Built with brand-new LiFePO4 cells. The refined casing enables efficient thermal dissipation and strong anti-corrosion performance, extending the battery's service lifespan significantly.
Reliable Charging & Discharging
Supports 0.5C continuous operation with steady current output. It runs for extended periods without current fluctuation or overheating, guaranteeing uninterrupted power delivery.
Strong Surge Load Handling
Delivers 60A transient peak current for up to 3 seconds, accommodating the momentary high-power startup loads of many industrial and mechanical devices.
Low Standby Power Draw
Standby consumption stays under 10mA, slowing the natural self-discharge rate. The unit retains ample stored energy even after sitting idle for extended durations.
Accurate SOC Tracking
Integrated smart BMS monitors battery status in real time. SOC error is kept within 2%, providing precise readings of remaining battery capacity for easy status review.
Enhanced Safety Design
LiFePO4 chemistry delivers inherently stable properties with flame-retardant and explosion-resistant features. Multi-layer built-in protection supports long-duration continuous safe operation.
Application Scenarios
This large-capacity lithium battery pack works well for residential solar storage systems, standalone off-grid power stations, industrial UPS backup power, telecom base station power supplies, high-capacity portable outdoor power units, plus medium and large low-speed electric vehicles and construction machinery.
