Stackable High Voltage Lithium Battery

As a professional high quality Shangming Stackable High Voltage Lithium Battery manufacturer,we will offer you the best after-sale service.Stackable high-voltage (HV) lithium batteries use a modular architecture where individual battery modules (typically 2.5–5.12kWh each) are connected in series to achieve voltages ranging from 100V to 500V+. Unlike traditional 48V systems, HV batteries operate at 200V–400V DC, enabling greater charge/discharge power at lower current, which improves overall system efficiency and reduces cable sizing requirements.

These batteries can provide reliable power supply for various devices or systems. This stackable high-voltage lithium battery is designed in a modular way, making it easy to expand and maintain, with a capacity of up to 40.9 kilowatt-hours. Shangming offers you a stable and reliable high-voltage energy storage system using advanced lithium iron phosphate (LFP4) technology.

Stackable High Voltage Lithium Battery pack integrates advanced BMS with real-time monitoring, overcharge/over-discharge protection, and thermal management for enhanced safety and longevity. Modular stackable design allows flexible capacity expansion while maintaining uniform current distribution. All units comply with UN38.3, IEC62133, and RoHS standards.

Smart BMS & Full Protection Integrated Battery Management System (BMS)

Working Principle

Modular Series Connection Principle

Each independent lithium battery module has fixed standard voltage and capacity. Multiple modules are stacked and connected in series through built-in high-voltage communication and power terminals, so the total system voltage is increased by series connection, realizing high-voltage DC output easily.

Built-in BMS Balance Management

Every battery module is equipped with independent intelligent BMS system. Stackable High Voltage Lithium Battery monitors cell voltage, current, temperature and SOC in real time. Stackable High Voltage Lithium Battery performs active cell balancing automatically to keep consistent voltage among all stacked modules, avoid uneven charge and discharge.

Energy Storage & Power Conversion Matching

The  High Voltage Lithium Battery stores electric energy converted by solar panels or commercial power in lithium cells in DC form. The high-voltage direct current is transmitted to off-grid solar inverter, then converted into stable AC power for household and commercial loads. High voltage reduces working current and lowers line power loss.

Intelligent Charge & Discharge Control

During charging, BMS limits charging current and voltage to prevent overcharge; during discharging,  The  High Voltage Lithium Battery  cuts off output timely to avoid over-discharge. Stackable High Voltage Lithium Batteryalso has over-temperature, over-current, short-circuit and insulation protection to ensure safe operation.

Parallel Expansion & Energy Dispatching

Support multi-group high-voltage battery stacks parallel connection. The whole system realizes unified energy dispatching, flexible adjustment of total energy storage capacity and output power, adapting to different power consumption demands.
