Precautions for Using Triangle Pack Batteries

To ensure safety, maximize lifespan, and reduce after-sales issues, Triangle Pack Batteries should be handled, stored, and maintained properly throughout their lifecycle. Below are the key precautions B2B customers should follow:

 

  • Use the Correct Charger: Always use a charger compatible with your battery’s voltage and BMS. Over-voltage or under-voltage charging can damage cells and pose safety risks.

  • Avoid Deep Discharge: Regularly discharging below 2.5V/cell reduces cycle life. Recharge before full depletion for longer service.

  • Monitor Temperature: During charging and discharging, keep the battery within a safe operating temperature range (-20°C to 55°C). Avoid exposure to high heat or freezing environments.

  • Handle with Care: Do not puncture, crush, or drop the battery. Use padded packaging for shipping or storage.

  • Prevent Short Circuits: Avoid direct contact between terminals and conductive materials. Ensure connectors are clean, dry, and properly insulated.

  • Check for Physical Damage: Inspect for cracks, bulges, or broken terminals before installation or reuse. Damaged batteries should not be used.

  • Follow Proper Storage Conditions: If unused for a long period, store the battery at 50–70% charge in a dry, ventilated area. Avoid moisture and direct sunlight.

  • Use Protective Housing: When installed inside bike frames or bags, ensure the pack is secure, protected from vibration, and not compressed by other components.

  • Don’t Disassemble Without Authorization: Opening sealed battery packs without technical support may cause damage or void warranty.

  • Dispose Responsibly: Follow local regulations when recycling or disposing of lithium batteries. Do not burn or discard in regular trash.

 

By observing these precautions, e-bike brands and distributors can reduce risk, lower maintenance costs, and ensure safe use across their supply chain or service network.

How to Choose the Right Triangle Pack Battery?

Choosing the right Triangle Pack Battery is essential to ensure your e-bike project delivers optimal performance, safety, and range. Use the checklist below to make a well-informed decision tailored to your application:

  1. Define Your Application
    Understand your e-bike type and usage. Are you building an off-road, utility, or long-range commuter bike? Triangle packs are best suited for mid-drive, high-power, or integrated frame designs.

  2. Check Frame Space & Mounting Constraints
    Confirm your bike frame has enough internal triangle space to install the battery. Consider waterproof bag designs or customized mounting brackets.

  3. Select Voltage & Capacity
    Choose 36V / 48V / 52V depending on motor compatibility. Match your desired range with capacity options (typically 13Ah–30Ah).

  4. Choose Cell Type & Configuration
    Decide between 18650 or 21700 cells, and select brands (Samsung, LG, EVE) based on performance, cost, and life cycle.

  5. Assess BMS Functionality
    Does your project require basic protection or advanced features like Bluetooth, CAN/UART communication, or temperature sensors?

  6. Confirm Connector & Output Interface
    Ensure the discharge and charging connectors (XT60, Anderson, DC2.5, etc.) are compatible with your controller and charger systems.

  7. Understand Operating Conditions
    Will your battery be used in cold, hot, or wet environments? Select models with appropriate waterproofing (IP rating), insulation, and temperature tolerance.

  8. Estimate Expected Lifespan
    Look for high-quality BMS and premium cells if your project demands longer cycle life (600+ cycles at 80% DOD).

  9. Balance Budget and Customization Needs
    Custom layouts, branding, and packaging add value but affect cost. Define which features are essential and where flexibility is allowed.

By reviewing these key points, you’ll be able to choose a triangle battery pack that integrates seamlessly into your product—and supports your performance and market goals.
