    FAQ

    If your questions are not answered in the below list, please
    contact us. info@dgwushin.com
    • What is the typical lifespan of your Li-ion and LifePO4 battery?

      The lifespan is measured in cycles. Our standard LiFePO4 batteries provide 3,000 to 5,000 cycles at 80% Depth of Discharge (DoD) while retaining over 80% of their original capacity. With typical daily use, this translates to a service life of 5-10 years, far longer than lead-acid batteries. Li-ion (NMC/Cobalt-based): Typical lifespan of 1500 - 2000 cycles (approx. 2-5 years of daily use).

    • How do I check the battery's status and health?

      Many of our advanced battery packs come with a Bluetooth module that allows you to connect to the BMS via a smartphone app. This lets you monitor real-time data such as voltage, current, state of charge (SOC), temperature, and cycle count. For basic models, the voltage can be checked with a multimeter.

    • Do your battery packs include a Battery Management System (BMS)?

      Yes, absolutely. Every one of our LiFePO4 battery packs comes with an integrated smart BMS. It protects the battery by providing: Over-Charge Protection. Over-Discharge Protection. Over-Current Protection. Short-Circuit Protection. Temperature Protection. Cell Balancing.

    • Do you provide custom services?

      Yes, we are a professional factory and welcome custom inquiries. We can customize: Voltage and Capacity (Ah). Shape, size, and terminal type. BMS parameters and software branding. Please contact our sales team with your specific requirements.
