Yachu 5.12 kWh  51.2V 100Ah Lithium Battery

The 5.12 kWh Yachu 51.2V LiFePO₄ Lithium Battery is a high-efficiency energy storage solution designed for hybrid and off-grid solar systems. With a nominal voltage of 51.2V and 100Ah capacity, it delivers approximately 5.12 kWh of usable energy.

Built using Lithium Iron Phosphate (LiFePO₄) technology, this battery offers enhanced safety, long cycle life, and consistent discharge performance compared to conventional lead-acid batteries. It supports deep discharge operation while maintaining voltage stability for inverter-based system.

Technical Specifications

Cell Technology & BMS

The battery uses Lithium Iron Phosphate (LiFePO₄) prismatic cells in a 16-cell configuration at 51.2V nominal, with high thermal stability chemistry. The integrated Battery Management System (BMS) provides overcharge protection, over-discharge protection, short circuit and overcurrent protection, and temperature monitoring and cell balancing

Applications

The battery is suitable for homes (solar backup and night-time power), offices (computers, lighting, routers), clinics (essential medical device backup), farms (solar water systems and lighting), workshops, and light commercial setups such as shops and small enterprises

Key Features

Notable features include 5.12 kWh usable storage, long-lifespan LiFePO₄ chemistry, high depth of discharge capability, stable discharge voltage profile, parallel expansion capability, a compact wall-mounted design, and low maintenance requirements

Installation Notes

The battery should be installed indoors in a dry, ventilated area. Correct DC isolators and protection breakers are required, and the inverter must be configured to a lithium charging profile. Direct sunlight and moisture exposure should be avoided, and proper cable sizing is essential to handle current drama.

Compatibility

The battery is compatible with 48V hybrid solar inverters, off-grid inverter systems, MPPT charge controllers, solar panel arrays, and AC distribution panels
