🔋 High Energy Density — 269.8Wh/kg

The Samsung INR18650-35E stands out for its impressive 269.8Wh/kg energy density, providing powerful energy storage in a lightweight design. This makes it perfect for applications that require maximum runtime without compromising on size or efficiency — from e-bikes to portable power tools.

This high energy-to-weight ratio enhances performance and extends range, making it a top-tier choice for high-efficiency battery systems.

⚙️ 3500mAh High Capacity for Extended Endurance

With a nominal capacity of 3500mAh, the Samsung 35E provides extended operation times for devices that require long-lasting, stable output. Whether powering an electric scooter, cordless drill, or backup power system, this cell offers reliable, sustained energy that reduces downtime and charging frequency.

📉 Smooth 3.6V Discharge Platform for Consistent Power

The 3.6V nominal voltage delivers a flatter, more linear discharge curve than typical 3.7V Li-ion cells.
✅ Reduced voltage fluctuation
✅ Improved equipment stability
✅ Smoother, more predictable performance across the discharge cycle

This makes the Samsung 35E ideal for precision-driven devices that demand consistent voltage behavior to protect sensitive components and deliver uniform output throughout operation.

🔁 Long Cycle Life & Reliable Durability

Built for endurance, the Samsung 35E maintains over 60% of its initial capacity after 500 cycles.
Even under frequent charge–discharge conditions, the cell continues to deliver stable power with minimal degradation — making it a durable and economical option for long-term use in e-mobility and industrial tools.

⚡ 8A Continuous Discharge — Ready for Higher Current Loads

The 35E supports continuous discharge up to 8A, striking the perfect balance between capacity and power. This allows it to operate reliably in devices with moderate to high current draw, such as:

• 🚴‍♀️ Electric bicycles (E-bikes)

• 🛴 Electric scooters

• 🔧 Cordless power tools

• 🔦 High-performance flashlights

Its low internal resistance ensures minimal heat buildup and superior energy efficiency during operation.

🌡️ Excellent Consistency for Battery Pack Assembly

The Samsung 35E’s tight parameter consistency in voltage, resistance, and capacity ensures seamless performance in multi-cell packs. It’s a popular choice for battery engineers building series-parallel configurations for e-bike and scooter packs, ensuring stable operation, even load distribution, and reduced balancing requirements.
