Import 14.8v Lithium Ion Battery Pack — Buy in Bulk from Supplier in China

Joolee Battery (Shenzhen) Co., Ltd. supplies this 14.8V lithium ion battery pack from its base in Guangdong, China, a region central to global battery manufacturing. The pack operates at a nominal voltage of 14.8V, which corresponds to a 4-series (4S) lithium-ion cell configuration. The listing specifies a maximum charge voltage of 16.8V and a capacity range spanning from 100mAh to 50Ah, indicating the product line covers both small-scale electronics and substantial energy storage applications.

Lithium-ion cells in this voltage class typically use a lithium cobalt oxide (LiCoO2) or lithium nickel manganese cobalt oxide (NMC) chemistry, with a standard discharge cutoff around 10V to 12V to protect cell longevity. The supplier notes the pack includes built-in safety features, which in industry terms usually means an integrated battery management system (BMS) for overcharge, over-discharge, and short-circuit protection. Typical cycle life for such packs ranges from 500 to 1000 cycles at 80% depth of discharge, depending on the specific cell chemistry and operating temperature.

This 14.8V configuration is commonly sourced for use in portable medical devices, telecommunications backup systems, electric bicycles, and industrial robotics. Buyers in these sectors often require specific connector types, wire harness lengths, and custom BMS parameters, so confirming these details with Joolee Battery before placing an order is advisable. The supplier's location in Shenzhen provides access to established logistics corridors for international shipping, with FOB and CIF terms typically available for bulk orders.

Joolee Battery (Shenzhen) Co., Ltd. is located at No.165, 9Rd District, Dalang, Longhua, Shenzhen 518109, Guangdong, China. The company is listed as an 'imported' tier supplier on the platform, with a 'harbor' trust designation. The listing data shows a 0% response rate and an average response time of 0 hours, which means buyers should verify current communication responsiveness directly before initiating a sourcing inquiry.

The supplier's product listing focuses on lithium-ion battery packs, specifically a 14.8V model with a broad capacity range. The listing mentions that products come with certifications such as ISO and CE, but it does not provide specific certificate numbers or issuing bodies. A buyer would need to request copies of these certificates directly from Joolee Battery to confirm their validity and scope for their target market's regulatory requirements.
