18650 Battery Pack

Shenzhen Hysincere Battery Co., Ltd. designs and manufactures custom 18650 battery packs for B2B customers who need reliable, repeatable power in compact formats. Founded in Shenzhen in 2013 and recognized as a China National High-Tech Enterprise, Hysincere operates from its Shenzhen headquarters with production in Dongguan. We build 18650 packs from 1S1P up to 7S8P configurations, with PCM or BMS protection engineered in-house to match your application's voltage, capacity, discharge, and safety requirements.

Custom 18650 Pack Configurations from 1S1P to 7S8P

The 18650 format remains a benchmark in lithium-ion because it balances energy density, thermal behavior, and cost. Our engineering team configures cells in series and parallel to meet your target voltage and capacity — from single-cell 1S1P assemblies for compact devices to 7S8P packs for higher-voltage, higher-capacity systems. Each pack is defined by the application, not by a catalog number: cell selection, nickel strip or wire bonding, insulation, encapsulation, and connector choices all follow your mechanical and electrical constraints.

Because we control BMS design internally, protection thresholds, communication options, and cell balancing can be tuned to your duty cycle. Depending on the project, packs can include overcharge, over-discharge, over-current, short-circuit, and temperature protection, with optional Bluetooth or communication interfaces where the application calls for monitoring. Certificates are available upon request for management systems and product compliance.

Applications: E-bike, Robot, Medical, and Smart Home

Custom 18650 packs serve markets where size, weight, and cycle life matter:

• E-bikes and light electric vehicles — packs configured for stable discharge and vibration resistance.
• Robotics and automation — compact formats with predictable output for continuous duty.
• Medical and portable equipment — engineered for consistent performance and safety.
• Smart home and IoT devices — small-series and parallel builds for space-constrained enclosures.

Hysincere also manufactures LiFePO4 battery packs, sodium-ion batteries, and energy storage systems, alongside solid-state development. That range lets us recommend the right chemistry for your 18650 project — or propose an alternative when a different format or chemistry better serves the use case. Typical products across our portfolio include the LF12100-S-T50 (12.8V 100Ah, IP65, Bluetooth, ≥4500 cycles), the LN12100N-BL sodium-ion 12V 100Ah pack, the GF51105N-B 48V 105Ah golf cart battery, and the EF51200W-L wall-mounted storage unit.

OEM/ODM Partnership and Export Support

We work as an OEM/ODM partner: share your voltage, capacity, dimensions, connectors, and environmental requirements, and we will define the 18650 pack configuration and protection strategy around them. Applications we support include RV, marine, golf cart, home energy storage, industrial equipment, and lead-acid replacement.

Hysincere exports to Europe, the Americas, Australia, Japan, South Korea, and Southeast Asia. Whether you are developing a new product or replacing an existing 18650 pack, our team can support prototyping through volume production.
