Description

Our 12V 120Ah LiFePO4 Battery (Group 31) is a premium lithium power solution engineered for demanding applications. As an innovative lithium battery manufacturer, we deliver OEM-ready energy storage systems that combine high capacity, extended lifespan, and robust safety features for commercial users.

Key Features

1536Wh Energy Density: Lithium iron phosphate chemistry provides 120Ah capacity (12.8V) with 100% usable discharge capacity, outperforming lead-acid equivalents by 300% cycle efficiency.
Military-Grade Durability: 6,000+ cycles at 80% DoD with <2% annual capacity loss, engineered for 10+ year service life in marine/RV applications. Smart BMS Protection: 15-layer safety system prevents overcharge (¡Ü14.6V), deep discharge (¡Ý10V), and thermal runaway (-20¡ãC to 65¡ãC operational range).
Space-Optimized Design: Compact Group 31 footprint (330¡Á172¡Á215mm) with 13.5kg weight simplifies retrofitting in existing equipment racks.

Product Description

This OEM-focused lithium battery delivers 150A continuous/300A peak current for marine thrusters, RV inverters, and solar storage systems. The modular architecture supports parallel connections up to 4S4P configurations for 48V/480Ah systems. Proprietary cell balancing technology maintains <50mV voltage differential across 4000+ cycles, while IP67-rated casing withstands saltwater corrosion and vibration impacts. As a certified lithium battery manufacturer, we offer white-label customization including: - Bluetooth-enabled BMS with SOC monitoring - Terminal types (M8/M10 studs or SAE posts) - Heated battery options (-35¡ãC charging capability)

Why Choose Our OEM Lithium Solutions?

UN38.3 Certified Safety: Full compliance with lithium battery transportation requirements
Flexible Scalability: Stackable design supports 12V-48V systems without voltage drop
Zero Maintenance Operation: Eliminate acid leaks and water refills common in lead-acid alternatives

What Applications Suit the 12V 120Ah Lithium Battery?

Ideal for:
– Trolling motor power systems (5+ hours runtime @ 30A draw)
– Off-grid solar storage (3.5kWh daily output with 80% efficiency)
– Emergency backup systems (72h UPS runtime for 500W loads)

How Does This Compare to Traditional Batteries?

Our lithium battery provides 5X faster charging (0-100% in 4 hours @ 30A) versus 8+ hours for AGM equivalents. The 90% depth of discharge capability triples usable capacity compared to lead-acid’s 50% limit, while requiring 60% less space and weight.
