This 12V 150Ah lithium-ion battery pack is a high-capacity, deep-cycle energy storage solution suitable for off-grid solar systems, home backup power, RVs, marine applications, and other energy storage applications. The battery uses high-quality lithium iron phosphate (LiFePO₄) cells, providing stable power output, long cycle life, and excellent safety performance.

Compared to traditional lead-acid batteries, lithium iron phosphate batteries offer longer lifespan, higher usable capacity, lighter weight, faster charging speeds, and virtually maintenance-free operation. An integrated battery management system (BMS) continuously monitors battery status and provides multiple protection functions to ensure reliability in daily use.

• Deep-cycle design for frequent charge and discharge operation
• LiFePO₄ chemistry for excellent thermal and chemical stability
• Long cycle life compared with conventional lead-acid batteries
• Built-in BMS for comprehensive battery protection
• High usable energy for daily solar energy storage
• Low self-discharge during long-term storage
• Lightweight and compact compared with equivalent lead-acid batteries
• Maintenance-free operation

• Off-grid cabins and tiny houses with daily cycling loads
• RV and van conversions running fridges, lights and water pumps
• Rooftop solar arrays with self-consumption and time-shift needs
• Backup for freezers, medical equipment and home offices
• Boat house banks and dock-side charging stations
• Telecom shelters and remote monitoring nodes

We provide comprehensive service and technical support for deep-cycle lithium battery packs, helping customers select, customize, test, and deploy reliable battery solutions for different applications. From initial battery design to mass production, our engineering and sales teams provide professional support throughout the project.

We help customers select the appropriate lithium battery based on:

• Required voltage and capacity
• Continuous and peak discharge current
• Charging requirements
• Available installation space
• Operating temperature
• Application load and duty cycle
• Required cycle life
• BMS and communication requirements

Our technical team provides support for Battery Management System (BMS) configuration and battery protection requirements. Depending on the application, BMS functions can include overcharge, over-discharge, overcurrent, short-circuit, temperature protection, and cell balancing.

Communication functions can also be integrated when required for applications involving monitoring, control, or system integration.

Our support does not end after shipment. We provide ongoing technical assistance for battery installation, charging, operation, troubleshooting, and application-related questions.

Customers can contact our technical team for assistance with:

• Battery charging issues
• Abnormal voltage or current
• Battery communication
• Installation questions
