Dji 4 battery manufacturers

Buyers must ensure the battery is a High-Density LiPo 4S with a capacity of 5870mAh and a voltage of 15.2V. It is critical to verify the presence of an Intelligent Battery Management System (BMS), which monitors cell status in real-time and provides over-charge/over-discharge protection. For B2B procurement, confirm the cycle life (typically 200+ cycles) and the discharge rate to ensure flight stability.

Due to the volatile nature of lithium batteries, products must have UN38.3 certification for safe transport. For market entry, ensure the batteries carry CE, FCC, and RoHS markings. Additionally, a valid MSDS (Material Safety Data Sheet) is mandatory for customs clearance and air freight compliance. Always request UL 2054 certification if importing into the North American market to ensure electrical safety.

Original batteries feature proprietary firmware that communicates directly with the DJI GO 4 app. When sourcing third-party alternatives, check for firmware compatibility to avoid 'non-genuine battery' warnings that can lock flight capabilities. Look for suppliers on Made-in-China.com who provide Grade A cells and offer a performance guarantee that matches the original 30-minute flight time.

Batteries should be stored at a 50% charge level in a cool, dry environment (22°C to 28°C). Ensure the inventory features an auto-discharge function that triggers after 10 days of inactivity to prevent swelling. For long-term warehousing, a monthly voltage check is recommended to prevent cells from entering a deep-discharge state, which can render the stock unsellable.

Lithium batteries are classified as Class 9 Dangerous Goods. You must use a freight forwarder experienced in DG (Dangerous Goods) shipping. While air freight is faster, it is highly regulated and expensive; sea freight (LCL/FCL) is more cost-effective for bulk orders but requires specialized packaging (UN-approved boxes) and fire-resistant labeling.

Utilize Secured Trading Services on Made-in-China.com to ensure payment is only released upon confirmation of delivery. Before placing a large order, conduct a factory audit or hire a third-party inspector to perform a Random Sampling Test, focusing on internal resistance and capacity consistency across different batches.

Focus negotiations on warranty terms and RMA (Return Merchandise Authorization) policies. Since batteries are consumables, negotiate a defective rate allowance (e.g., 1-2% replacement units) included in the initial shipment. For orders exceeding 500 units, aim for a 15-20% discount off the sample price and request customized branding/packaging if you are an OEM buyer.

Be aware of anti-dumping duties or specific tariffs on electronics (such as Section 301 tariffs for US buyers). Ensure the HS Code (typically 8507.60) is correctly declared to avoid customs delays or fines. Stay updated on export restrictions from the country of origin regarding dual-use technologies (civilian/military drones).
