ABS Cell Holders for Lithium Battery Packs
Discover the significant advantages of using ABS cell holders over traditional adhesive bonding or cable tie methods in lithium battery pack assembly.
Safety and Reliability
This represents the most critical advantage of cell holders.
- Superior Insulation: The holder itself is an insulating material, effectively isolating each cell's metal casing.
- Mechanical Strength and Stability: The frame provides robust mechanical support, securely anchoring cells in their designated positions.
- Thermal Management Support: Precision bracket design creates uniform gaps between cells, forming effective heat dissipation channels.
- Preventing Thermal Runaway Propagation: Optimized spacing design slows the spread of thermal runaway from a single cell to adjacent cells.
- Consistent Pressure Distribution: Through structural design, the frame applies uniform constraint force to cells.
Production Efficiency and Manufacturability
ABS cell holders streamline the battery assembly process.
- Modular and Standardized Design: The frame enables battery assembly like "building blocks," achieving modularity.
- Streamlined Assembly Process: Cells can be quickly and accurately inserted into the bracket's slots.
- Automation-Friendly: The bracket's regular structure is highly suitable for robotic gripping, positioning, and assembly.
- Reduced Precision Requirements: Simplifies production processes and reduces dimensional precision requirements for cell suppliers.
Maintenance and Recyclability
ABS cell holders offer significant advantages throughout the battery lifecycle.
- Easy Disassembly and Repair: Units assembled with brackets can be relatively easily disassembled and replaced.
- Environmental Sustainability and Recyclability: At end-of-life, cells can be readily separated from plastic frames for individual recycling.
- Cost-Effective Maintenance: Reduces the need for complete battery pack replacement when only a few cells fail.
- Compliance with Environmental Standards: Meets increasing regulatory requirements for battery recyclability.
Structural Performance and Lightweighting
ABS cell holders enhance the overall performance of battery packs.
- Enhanced Structural Integrity: The assembled cell modules function as robust structural components.
- Achieving Lightweight Design: High-performance engineering plastic brackets significantly reduce battery pack weight.
- Improved Energy Density: Lighter weight contributes to higher energy density and extended range.
- Vibration and Impact Resistance: Meets rigorous testing standards for automotive applications.
Consistency Assurance
ABS cell holders ensure uniform performance across the battery pack.
- Maintaining Consistent Cell Spacing: Ensures uniform thermal conditions around each cell.
- Extended Battery Lifespan: Consistent operating temperatures help maintain overall battery pack health.
- Precise Component Alignment: Provides accurate positioning for busbars and connection points.
- Uniform Electrical Performance: Consistent physical arrangement contributes to stable electrical characteristics.
Enhanced Safety
ABS cell holders provide superior electrical insulation and mechanical stability, significantly reducing the risk of short circuits and thermal runaway events.
Streamlined Production
The modular design allows for faster, more automated assembly processes, reducing production time and costs while improving consistency.
Easy Maintenance
Individual cells can be replaced without discarding the entire battery pack, extending product lifespan and reducing waste.
Environmental Benefits
ABS holders facilitate recycling by allowing easy separation of battery components, supporting circular economy principles.

Key Features and Advantages
Ultra-High Energy Density
The 50G cell achieves a capacity of 5000mAh, ranking among the highest in the 21700 format. Its energy density is exceptionally high (typically exceeding 700Wh/L), meaning it stores more electrical energy within the same volume. This makes it ideal for applications demanding stringent endurance requirements.
Superior Discharge Performance
Maximum continuous discharge current reaches 9.8A, far exceeding typical high-capacity cells (usually around 5A). This enables the 50G to serve not only low-rate devices but also effectively balance capacity and power demands, making it suitable for equipment requiring instantaneous or sustained high-power output.
Low Internal Resistance
An internal resistance of ≤18.5mΩ ensures minimal voltage drop and heat generation during high-current discharge, enhancing discharge efficiency and safety.
Additional Information
Applications
Electric vehicles, power tools, energy storage systems, high-end flashlights, and portable electronic devices requiring high capacity and power.
Safety Features
Includes overcharge protection, over-discharge protection, short circuit protection, and thermal protection mechanisms.
Operating Temperature
Charge: 0°C to 45°C; Discharge: -20°C to 60°C (optimal performance between 15°C and 35°C).
Battery Management System
Core Protection Functions
Overcharge Protection
If any cell voltage exceeds safe maximum threshold, the charger is permanently disconnected.
Example: 4.25V ± 25mV
Overdischarge Protection
If any cell voltage falls below safe minimum threshold, the load is disconnected.
Example: 2.8V ± 50mV
Overcurrent Protection
Discharge is interrupted when current continuously exceeds predefined limit.
Short-circuit Protection
Operates within microseconds to disconnect the circuit in event of a dead short.
Overtemperature Protection
Operation is halted if battery or BMS temperature exceeds safe upper limit.
Under-Temperature Protection
Charging at low temperatures is prohibited to prevent lithium plating.

Charger Protection Features
Advanced safety mechanisms for reliable charging
Overvoltage Protection (OVP)
Normal
Function: If the charger's internal voltage control system fails and the output voltage abnormally rises above a safe threshold (e.g., over 60V), the charger immediately shuts off the output.
Overcurrent Protection (OCP)
Normal
Function: If the output current exceeds the set maximum limit (e.g., 11A-12A) due to some reason (e.g., an internal battery short), the charger automatically reduces the current or shuts off the output.
Short Circuit Protection (SCP)
Normal
Function: If the positive and negative output terminals are accidentally short-circuited, the charger instantly shuts off the output within milliseconds without causing damage. After the short circuit is eliminated, a restart is usually required to resume operation.
Overtemperature Protection (OTP)
Normal
Function: The charger has an internal temperature sensor. If the internal temperature exceeds a safe limit (e.g., 85°C) due to excessive ambient temperature or fan failure, the charger automatically reduces the charging power or stops charging until the temperature returns to normal.
Reverse Polarity Protection
Normal
Function: If the user accidentally inserts the charger with the positive and negative terminals reversed, the charger will not operate without causing damage.
Auto Power Off / Charging Indicator
Charging
Function: This isn't a simple physical power-off. Instead, when the charging current drops to a certain value (e.g., 0.5A, called the "cut-off current"), the battery is deemed fully charged and the output is automatically switched to a slight trickle or completely shut down, with the indicator light turning from red to green.
