The Bluetooth speaker lithium battery supplied by Sum Electronics Technology Co., Ltd. is a 3.7V lithium-ion cell with a capacity of 500mAh and physical dimensions of 6.5mm x 24mm x 43mm, designed for compact portable audio devices. It uses LiCoO2 and Li-NMC cathode chemistry with a maximum momentary discharge current of 15C and operates within a temperature range of -40°C to 80°C. The cell includes an integrated protection circuit to prevent overcharge, over-discharge, and short-circuit conditions.
This battery is built to industry-standard IEC62133 and UN38.3 safety requirements for transport and use in consumer electronics. The cell chemistry supports approximately 500 charge cycles while retaining at least 80% of its original capacity. Typical packaging for these cells is in dry, static-free environments with individual insulation to prevent cell-to-cell contact during shipment. The supplier does not list any proprietary cell chemistry beyond standard lithium-ion formulations, and the product is not marketed as a high-capacity or fast-charge variant.
These batteries are primarily sourced by OEM manufacturers of wireless speakers, portable audio devices, and compact medical instrumentation in Europe and China. Buyers typically order in bulk for integration into finished products. Trade terms are not specified in the listing, but standard packaging is in blister packs or bulk trays. Buyers should confirm minimum order quantities and lead times directly with the supplier, as these are not disclosed.

Before placing an order, verify the exact cell chemistry, discharge curve, and protection circuit specifications with Sum Electronics. Confirm the batch-to-batch consistency of capacity and internal resistance, as these can vary between production runs. Request a sample for performance testing under your device’s load conditions. Do not assume compatibility with existing designs unless the dimensions and electrical profile match exactly.
Lead time and Incoterms are not disclosed in the listing. Buyers must confirm whether shipments are FOB Guangzhou or EXW from Guangdong, and whether payment is via T/T, LC, or other terms. Standard lead time for bulk orders is typically 2-4 weeks, but this can extend during Chinese holidays. Always request a signed packing list and certificate of origin to clear customs.
For quality assurance, request a sample batch and perform voltage consistency checks, internal resistance measurements, and cycle life tests. Inspect packaging for signs of moisture exposure or physical damage. Ensure each shipment includes a batch traceability label and MSDS documentation. Retain samples for future reference in case of field failures or warranty claims.
