Product Overview: Why Choose JSK 32140 LiFePO4 15Ah Battery?

The JSK 32140 LiFePO4 15Ah battery is a game-changer in the lithium battery industry, featuring advanced Lithium Iron Phosphate (LiFePO4) chemistry — widely recognized as the safest and most durable lithium battery technology available today. This cylindrical cell (32mm diameter × 140mm length) delivers a nominal voltage of 3.2V, true 15Ah capacity (minimum 14.5Ah), and a 15A continuous discharge current (1C rate), providing the perfect balance of power, energy density, and longevity for your critical applications.

What sets this JSK LiFePO4 battery apart from other lithium-ion technologies:

• Unrivaled Safety: LiFePO4 chemistry is inherently stable, with no thermal runaway risk, even under extreme conditions like overcharge, short circuit, or physical impact

• Ultra-Long Cycle Life: 3000+ deep cycles (80% DOD) — 3-5 times longer than traditional lead-acid batteries and 2-3 times longer than standard lithium-ion batteries

• Flat Discharge Curve: Maintains consistent 3.2V voltage throughout 90% of discharge, ensuring stable performance for your devices

• Wide Temperature Range: Operates reliably from -20°C to 60°C, making it ideal for outdoor applications in harsh weather conditions common in EU/US regions

• Eco-Friendly: 100% recyclable, non-toxic, and free from heavy metals like lead, cadmium, or mercury

Key Features & Benefits

Core Performance & Quality Assurance

• 100% Authentic JSK Grade A Cells: Directly sourced from JSK with full traceability — each cell undergoes strict quality control tests (capacity, voltage, internal resistance, safety) before leaving the factory

• True 15Ah Capacity: Nominal 15Ah (minimum 14.5Ah) at 0.2C discharge rate, ensuring consistent energy delivery for your applications

• 15A Continuous Discharge: 1C discharge rate (15A) with 30A pulse discharge capability, providing enough power for electric vehicle motors and high-demand storage systems

• Low Internal Resistance: 1.8–2.5mΩ ultra-low impedance for efficient energy transfer and minimal heat generation during charging/discharging

• No Memory Effect: Can be charged at any time without reducing battery capacity, making it user-friendly for all applications.

•
