    The C discharge rating is a measure of how quickly a battery can safely discharge as a multiple of the battery's capacity. For example, a 5Ah battery with 1C rating means that it can be discharged at 5A, a 5Ah battery with 3C rating can discharge at 15A. The C rating is the maximum safe discharge rate of the battery. Exceeding the C rating can lead to reduced battery life, overheating, damage and even a fire risk.

    Voltage

    Battery voltage refers to the potential difference between the positive and negative terminal, it directly influences the performance of your electrical system, usually higher the better. However do ensure that your device is compatible with your current voltage selection.

    Amp-Hours

    Amp-hours (Ah) is a unit to measure the capacity of a battery. Picture Ah as the "fuel tank" of a battery, representing its ability to store energy. A higher Ah rating indicates a larger fuel tank and a greater amount of energy storage. This means that a battery with a higher Ah rating can power a device for a longer duration.

    Manufacturing Location

    The quality and cost of workmanship are different around the world, manufacturing at our chinese facility is cheap but comes with caveats for example slightly lackluster knowledge handling high discharge 18650 and 21700 packs 150a and above. Manufacturing at our singapore facility comes with a cost but with increased customer transparency, better workmanship handling high discharge 18650 and 21700 packs.

    For those tranny fans who like her work and insist on buying her battery.
    We will forward your order to her accordingly, battery will be built at her place, and will either be delivered to you, or collection will be arranged at her place at 1 tampines north drive 1

    Your cell selection is allocated for our dogeTune singapore facility only
    since there is only so few in inventory that manufacturing in our chinese facility will take too much flexibility away from us to serve our customers in a timely manner, and also wont add any effeciency or any significant cost savings into the process

    Discharge Port

    The discharge port is where the battery releases its stored energy to power connected devices. A high-quality discharge port ensures efficient energy transfer and safe operation, reducing the risk of voltage drops or interruptions. The right port will support your device's required current, ensuring optimal performance and longevity. It's crucial to choose a port compatible with your equipment to prevent potential damages and maintain the safety standards of your electrical system.

    Charging Port

    The charging port is the gateway to replenishing your battery's energy reserves. An effective charging port ensures a secure connection, swift energy transfer, and a reduced risk of overheating during the charging process. It's essential to ensure compatibility between the charger's plug and the battery's charging port to guarantee a proper charge cycle, enhancing battery life and performance. Remember, a good match between charger and port will prolong the battery's lifespan and maintain safety.

    ⚠️Warning⚠️ Fire/Explosion Short Circuit Risk

    Proceed with caution, This is the worst charging port on the planet, If you insist, we will make you an GX16-3 to xt90 adaptor instead of connecting the GX16-3 port to the battery directly

    Capacity Grading

    Capacity Grading is a crucial process to ensure uniformity and consistency in the performance of individual battery cells. This process groups cells based on minute differences in milliampere-hours (mAh) to ensure that batteries in the same pack have very similar capacities. Lower mAh range gradings lead to more precise matches, reducing the chance of future complications due to mismatched capacities, like imbalanced discharging or premature wear.

    50mAh range: This is our standard range
    ensuring a good balance of performance and value. This is also the range our cells are initially controlled to upon arrival from our suppliers.

    25mAh range: A premium grading that offers a tighter capacity match
    reducing potential issues in the long run. This option requires additional testing on our part to ensure that every cell meets this stringent criterion, hence a nominal fee will be charged to cover the added labor and equipment time. Choosing this grading can be especially beneficial for high-performance applications where every detail matters.
