Key Features
- 5000mAh High Capacity: Typical capacity of 5000mAh with a 4900mAh minimum rating, delivering extended runtime and consistent energy output across professional high-drain applications.
- Extreme 60A Continuous Discharge: Supports up to 40A continuous discharge without thermal cutoff and up to 60A continuous with 80°C surface temperature management for maximum sustained output.
- 180A Peak Pulse Capability: Handles pulse discharge currents up to 180A for 5 seconds at 25°C, providing exceptional headroom for high-demand burst applications.
- Low Internal Resistance: Initial AC impedance of ≤4mΩ at 1kHz minimizes voltage sag under heavy load for stable, efficient power delivery throughout the discharge cycle.
- Long Cycle Durability: Rated for up to 600 charge/discharge cycles with ≥60% capacity retention, delivering reliable long-term performance in demanding service environments.
Overview
The Ampace JP50 is a high-performance 21700 lithium-ion battery cell engineered for extreme high-drain applications where both sustained current capability and long service life are essential design requirements. Delivering a typical capacity of 5000mAh at a nominal voltage of 3.58V, the JP50 supports up to 40A continuous discharge without thermal cutoff and up to 60A continuous with 80°C surface temperature management — backed by a 180A pulse discharge capability for 5-second bursts. An initial AC internal resistance of ≤4mΩ ensures minimal voltage sag and efficient energy transfer under sustained high-current loads. With a wide operating temperature range of -20°C to 80°C for discharge and a rated cycle life of up to 600 cycles at ≥60% capacity retention, the JP50 is built for reliability across extended professional use. Its unprotected flat-top 21700 format is designed for integration into engineered battery pack assemblies equipped with appropriate Battery Management System protection and thermal management solutions.
