1. Battery Capacity (mAh or Ah)

What does mAh mean?

Capacity measures the amount of energy a battery can store and deliver over time. It’s like the fuel tank of your car—it determines how long a device can operate before needing recharging. For example,

  • A battery with a capacity of 3000 mAh can deliver 3000 milliamperes (or 3ampere) of current for one hour before it needs recharging.
  • Similarly, a battery with 10000 mAh capacity can provide 10000 milliamperes (or 10amperes) of current for one hour.

When customizing lithium battery packs at Saphiion, we tailor capacities to suit your specific power requirements, whether for high-drain applications like power tools or long-duration needs in IoT devices.

2. Battery Voltage (V)

Voltage indicates the electrical potential difference between the positive and negative terminals of the battery. Just as different chemistry and appliances require different voltages, such as,

  • 3.2V for LiFePO4 battery;
  • 3.6V/3.7V for NMC lithium battery;
  • 5V for USB device;
  • 11.1V or 14.8V for medical device;
  • 12V/24V/48V for trolling motor and golf cart battery;
  • 24V/36V/48V/52V for electric bike battery;
  • 60V/72V for electric scooters battery;

Therefore, selecting the right voltage is crucial for compatibility and performance. At Saphiion, we specialize in designing 18650 21700 custom lithium battery packs with precise voltage outputs, ensuring seamless integration into your systems without compromising on efficiency or safety.

3. Battery Chemistry and Configuration

Lithium-ion batteries come in various chemistries (e.g., NMC battery, LFP battery) and configurations (e.g., cylindrical battery, prismatic battery). Each type offers unique characteristics in terms of energy density, lifespan, and safety profile. For instance,

  • NMC (Nickel Manganese Cobalt) batteries offer high energy density suitable for electric bicycles, electric vehicles;
  • While LFP batteries(Lithium Iron Phosphate, LiFePO4) prioritize safety and longevity, ideal for home energy storage;
  • Cylindricalbattery, such as 14500 battery, 18500 battery, 18650 battery, 21700 battery, 26650 battery, 32650 battery, 4680 battery…etc;

Saphiion’s expertise lies in recommending the optimal chemistry and configuration tailored to your application’s requirements, ensuring maximum performance and reliability.

4. Discharge Rate (C-Rate)

Discharge rate indicates how quickly a battery discharges its stored energy relative to its total capacity. It is often expressed as a multiple of the battery’s capacity (C-rate). For example,

  • A battery with a 1C discharge rate can fully discharge in one hour;
  • While a 2C discharge rate means it can discharge in 30 minutes.

Understanding discharge rates is crucial for selecting batteries that can sustain peak power demands without voltage drop or overheating. At Saphiion, we design custom lithium battery solutions with optimized discharge rates to ensure consistent performance and reliability under varying load conditions.

5. Discharge Current (A)

Discharge current refers to the rate at which electrical energy is drawn from the battery during use. It is typically measured in amperes (A). Higher discharge currents are required for devices with high power demands, such as electric vehicles or power tools. When designing your custom battery packs, Saphiion ensures that the discharge current capabilities match the operational needs of your application to maintain efficiency and longevity.

6. Cycle Life and Durability

Cycle life refers to the number of charge-discharge cycles a battery can endure before its capacity significantly diminishes. This is critical for applications requiring long-term reliability and minimal maintenance.

Saphiion’s custom lithium battery solutions are engineered for durability, featuring advanced materials and manufacturing techniques that extend cycle life and reduce operational and replacement costs over the battery’s lifespan. Whether it’s for consumer electronics or industrial equipment, our lithium batteries are designed to withstand rigorous use and deliver consistent performance.

7. Safety Features

Safety is paramount in custom lithium battery pack design. Saphiion integrates multiple safety features to mitigate risks associated with overcharging, short circuits, and thermal runaway. These include:

  • Battery Management System (BMS): Monitors and controls battery parameters to prevent overcharging and over-discharging.
  • Thermal Management: Ensures batteries operate within safe temperature ranges to prevent overheating and potential hazards.
  • Cell Balancing: Equalizes charge levels among individual cells to optimize performance and prolong battery life.
