4.How do you ensure the quality of the battery packs?

We use brand-new Grade A cells for all battery packs. Each one is tested for voltage, internal resistance, and capacity before being shipped to you.  

Battery Warnings & Tips

Customers must follow these guidelines to ensure the safe and proper use of the cells:

 

1.Battery Management System (BMS):

   - Install a reliable BMS to monitor and protect each cell.  

   - Share details of the BMS, including design, features, settings, and data formats, with EVE for review and record-keeping.  

   - Maintain a data log of cell performance throughout its use for troubleshooting and quality responsibility. If no monitoring records are available, the manufacturer will not provide quality assurance.  

 

2.Waterproof and Dustproof Design:  

   - Ensure the battery pack is protected against water and dust as per national standards.  

   - EVE is not liable for damages like rust or corrosion caused by poor waterproof or dustproof measures.  

 

3.Mixing Cells:  

   - Do not combine different cell types in the same system. Mixing cells voids quality assurance.  

 

4.Voltage and Temperature Compliance:  

   - Ensure the BMS operates within safe voltage and temperature limits.  

 

5.Low-Temperature Charging:  

   - Do not charge cells at temperatures below 0℃ or below the specified safety limits. Failure to follow this guideline voids quality assurance. Poor heat dissipation design may also affect performance, which is not the manufacturer's responsibility.  

 

6.Voltage Protection:  

   - If the cell voltage exceeds the limit, the system must take protective actions.  

   - If the cell voltage drops to the cut-off level, recharge promptly to prevent over-discharge. Over-discharge and voltage violations are not covered by quality guarantees.  



#Safety Precautions

 

- Avoid Water Contact:  

  - Do not submerge the battery in water. Store it in a dry, cool place when not in use.  

 

- Prevent Overcharging:  

  - Overcharging can cause overheating or fire. Protect against repeated overcharging failures using hardware and software safeguards.  

 

- Charging Time:  

  - Set a reasonable time limit for charging to avoid overheating or thermal runaway. Faulty BMS management must be addressed during design.  

 

- Charge Regularly:  

  - Avoid over-discharge by keeping the voltage above 2.8V during regular use.  

 

- High-Temperature Use:  

  - Never use or store the battery in high-temperature conditions. Keep the temperature below 65℃ during normal operation. If exceeded, the BMS should shut down the system.  

 

- Use Proper Chargers:  

  - Always use a charger specifically designed for lithium-ion batteries.  

 

- Follow Polarity Labels:  

  - Connect the positive and negative terminals as labeled. Reversing connections is prohibited.  

 

- Prevent Short Circuits:  

  - Never use metal objects to directly connect the terminals. Short circuits can cause fires or serious injuries.  

 

- Avoid Metal Contact During Transport or Storage:  

  - Do not transport or store batteries with metal items like hairpins or jewelry.  

 

- Handle With Care:  

  - Do not drop, hit, step on, or bend the battery.  

  - Avoid puncturing the battery with nails or sharp objects.  

 

- Prevent Mechanical Stress:  

  - Protect the battery from impact, pressure, or shocks that could lead to internal damage, overheating, or fire.  

 

- Avoid Static Electricity and Magnetic Fields:  

  - Keep the battery away from areas with strong static or magnetic fields to prevent damage to safety mechanisms.  

 

- Secure Installation:  

  - Fix the battery firmly to a solid surface. Keep power cords properly secured to prevent sparks or damage.  

 

- Avoid Improper Materials:  

  - Do not use plastic for sealing or electrical connections, as it may overheat and cause failures.  

 

- Handling Leaks:  

  - If electrolyte leaks onto skin or clothing, wash the area immediately with water. If it contacts the eyes, nose, or mouth, rinse thoroughly and seek medical help right away.  

 

- Abnormal Behavior:

  - If the battery shows unusual signs like odor, heat, discoloration, deformation, or leaks, stop using it immediately and remove it from the device or charger.  

 

- No Unauthorized Disassembly:  

  - Do not disassemble the battery without written permission from the manufacturer.
