Engineered for premium performance and intelligent control, this 52V 50AH lithium-ion battery is built with a 14S10P configuration of 140 original Samsung 21700 50G cells, ensuring exceptional capacity and long-term reliability. Encased in a robust metal shell, it features a built-in power level display for at-a-glance status checks.

At its core is an advanced smart BMS with Bluetooth connectivity, allowing for real-time monitoring of key parameters and remote control over charge and discharge functions via a dedicated mobile app. The battery is further protected by excellent waterproofing and comprehensive safety features.

To complete the package, a 58.8V 10A fast smart charger is included for rapid and convenient recharging. This battery system represents a perfect fusion of high power, smart technology, and robust safety.

The heart of our 52V 50AH battery pack is built entirely with genuine Samsung 21700-50G high-performance power cells. Renowned for their impressive 5,000mAh capacity and high energy density, these cells are the foundation for the pack's extended runtime and superior capacity.

Furthermore, the 50G cell's robust 9.8A continuous discharge rating ensures stable and powerful performance, even during high-demand applications.

By integrating these industry-leading cells, we guarantee that your device will benefit from longer operational times, dependable power delivery, and the proven safety and consistency of the Samsung brand, giving you ultimate peace of mind.

Our 52V 50Ah lithium battery is equipped with an intelligent Bluetooth BMS. This BMS (Battery Management System) serves as the core "brain" and safety guardian of the battery, ensuring safe, efficient, and long-lasting operation through real-time monitoring and intelligent control.

The key core safety protection features are as follows:

⚡ Short Circuit Protection

When a short circuit is detected at the output, the BMS cuts off the circuit within an extremely short time (microsecond level).

🔋 Overcharge Protection

The BMS monitors the voltage of each cell in real time. If the voltage of any cell reaches the set maximum safety threshold, the BMS immediately cuts off the charging circuit to stop charging.

📉 Over-discharge Protection

The BMS monitors the voltage of each cell in real time. If the voltage of any cell drops below the set minimum safety threshold, the BMS cuts off the discharge circuit to stop power output.

⚡ Overcurrent Discharge Protection

The BMS continuously monitors the discharge current. If the current exceeds the set safety limit, the BMS triggers protection and cuts off the discharge.

🔌 Overcurrent Charge Protection

The BMS monitors the charging current. If the charging current exceeds the charger's rated value or the battery's acceptable range, the BMS cuts off the charging circuit to protect the battery from high-current charging damage, extend battery life, and prevent overheating of both the charger and the battery.

⚖️ Active Cell Voltage Balancing

The BMS actively balances the cells by discharging or transferring energy from cells with higher voltage, ensuring the voltage of each cell tends to be consistent. This maximizes the usable capacity of the battery pack and significantly extends its overall lifespan.

This 52V 50Ah intelligent Bluetooth BMS not only provides multiple, rock-solid hardware safety protections—including overcharge, over-discharge, overcurrent, short circuit, and temperature protection—but also significantly optimizes battery lifespan through its cell balancing technology.

More importantly, its Bluetooth communication function transforms the battery from a "black box" into a transparent, interactive smart device. Via a dedicated APP, it allows you to monitor real-time data, receive fault warnings, and log historical data, truly putting you in full command of your battery's health and enabling safe, efficient, and intelligent energy management.

📊 Real-time Data Monitoring (via Bluetooth APP)

🔋 Total Voltage: Approx. 52V - 58.8V

📈 State of Charge (SOC): Accurate remaining battery percentage

⚡ Current: Real-time charging and discharging current

🌡️ Temperature: The core temperature inside the battery

🔄 Cycle Count: Complete charge-discharge cycles

🔍 Individual Cell Voltages: Voltage of each cell string

❤️ State of Health (SOH): Battery aging degree indicator

🚨 Fault Records & Alarms

The BMS records all historical protection events that have been triggered (such as over-voltage, overcurrent, over-temperature, etc.). When an abnormality occurs, the APP actively pushes alarm notifications.

⚙️ Parameter Settings & Access Management

Technicians or advanced users can use the APP to calibrate or adjust certain protection parameters (such as capacity, protection thresholds, etc.). Access passwords can also potentially be set to prevent unauthorized modifications.

For the high-capacity 52V 50Ah lithium battery, the metal shell is the core of its safety architecture. It is not just a "container" for the battery cells, but also a "guardian" that ensures stable power output under various demanding applications, providing you with reliable and long-lasting power assurance.

🛡️ Ultimate Protection Against Physical Impact

💥 Impact and Crush Resistance

It effectively resists impacts, drops, and crushing encountered in daily use. Working in synergy with internal shock-absorbing foam, it absorbs and dissipates significant impact force, fundamentally preventing internal short circuits caused by cell deformation and eliminating safety hazards.

📍 Superior Puncture Resistance

Compared to plastic materials, the metal shell offers much stronger resistance to sharp objects like nails and gravel, significantly reducing the risk of thermal runaway triggered by shell rupture.

🏗️ Stable Foundation, Ensuring Internal Integrity

The internal structure of a high-capacity battery pack is complex and precise. The metal shell provides a solid structural frame, ensuring the battery cells, BMS, and other components remain securely in place despite continuous vehicle vibration. This prevents connection point loosening and component wear, guaranteeing long-term operational reliability.

🌊 Robust Barrier for Environmental Isolation

🔒 Comprehensive Sealing

Combined with internal sealants, it effectively blocks the ingress of rainwater, moisture, and dust, easily withstanding harsh weather and wash-down environments, thereby protecting the internal circuitry and cells from corrosion and short circuits.

🧪 Corrosion Resistance

It also offers better resistance to corrosive substances like salt spray and chemicals, ensuring the battery's long-term durability in complex environments.

❄️ Efficient Heat Dissipation for Stable Performance

The excellent thermal conductivity of metal makes the shell a natural "heat sink." It rapidly draws out and evenly dissipates the heat generated during battery operation, preventing localized hot spots. This ensures performance stability during high-power discharge and effectively extends the battery's cycle life.

The high-definition power display equipped on our 52V 50Ah lithium battery is far more than a simple indicator light.

It is a direct and transparent information interface between you and your battery.

It translates the internal status of the battery into clear, precise data at a glance, providing you with an unprecedented sense of control and peace of mind.

Precise Power, Eliminate Range Anxiety

The display clearly shows the remaining battery level in real-time via a percentage (%) or voltage reading.

This allows you to precisely assess the achievable range for each trip, just like checking your phone's battery, enabling you to plan your journey and charging schedule effectively.

It effectively eliminates the "range anxiety" caused by the vague estimates of traditional indicator lights, making every journey more confident and relaxed.

Real-time Monitoring, Master Operational Status

During charging and discharging, the screen displays key parameters like current voltage and current in real-time.

You can directly observe whether charging is proceeding normally or if the battery is operating stably under high-power discharge.

This transparent monitoring transforms you from a passive user into an active manager of your battery.

Convenient Self-check, Enhanced User Experience

With a simple button press, you can instantly read all the information without any additional tools.

This "what you see is what you get" interaction greatly simplifies daily maintenance and status checks, making battery management and upkeep simpler and more intuitive than ever before.

This intelligently designed fast charger, meticulously crafted for 52V 50Ah lithium battery systems, is an all-in-one "Battery Energy Manager" that combines efficiency, safety, and intelligence.
