FAQ for Headlamp & Flashlight Batteries
A: Absolutely. We use high-discharge-rate cells and a robust BMS specifically designed to handle the very high current draw (often 3A or more) required for a light’s “turbo” or maximum brightness mode.
A: Yes, this is a very popular feature we specialize in. We can create a self-contained, protected battery pack with an integrated USB-C charging circuit, making the end-product more convenient for the user.
A: For a new custom design, our MOQ typically starts at 20,000 to 50,000 units, depending on the complexity of the pack and its electronics.
A: Our intelligent BMS includes multiple temperature sensors. If the battery’s temperature exceeds a safe limit (either from the LED’s heat or from high-current discharge), the BMS will automatically reduce the power or shut down to prevent damage, ensuring user safety.
A: We can design the battery pack with a fully sealed, ultrasonically welded housing and waterproof seals around any ports or contacts. This allows our pack to be a key component in your light’s overall IP (e.g., IPX8) waterproof rating.
A: After the design is finalized, the lead time for the first batch of functional prototypes, especially those with integrated charging, is generally 6-8 weeks.
A: A custom LiPo pack allows for much greater design freedom. It can be made in a flat, rectangular, or custom shape to create a more ergonomic and compact light, and can have charging and protection circuitry integrated directly into the pack.
A: Yes, we can integrate a simple multi-level LED indicator directly on the pack, or a smart BMS that communicates with your light’s main processor for a more detailed status display.
A: Yes. We manage the entire certification process to ensure your battery pack meets all required standards for your target markets, including CE, UL 2054, IEC 62133, and UN38.3.
A: Please provide your light’s power requirements (max Lumens and corresponding Amps), target runtime at various brightness levels, dimensional constraints, any IP rating or durability requirements, and your estimated annual volume.
