Key Features
- 5000mAh High Capacity: Strong runtime in a cell that doesn't ask you to give up current capability to get it — the JP50 holds 5000mAh typical with a 4900mAh minimum floor.
- Extreme 60A Continuous Discharge: 40A continuous with no thermal cutoff, and up to 60A with 80°C temperature management — serious headroom for serious builds.
- 180A Peak Pulse Capability: Short on burst power? The JP50 handles up to 180A pulse discharge for 5 seconds, covering even the most aggressive current spikes your application can throw at it.
- Low Internal Resistance: ≤4mΩ AC impedance keeps voltage sag minimal under heavy load — tighter voltage means better performance where it counts.
- Long Cycle Durability: Up to 600 cycles at ≥60% capacity retention means the JP50 is built for the long haul, not just impressive spec sheet numbers.
Overview
The Ampace JP50 is a cell built for builders who need both capacity and current without compromise. At 5000mAh typical and 3.58V nominal, it delivers meaningful runtime — and then backs it up with 40A continuous discharge without any thermal cutoff, stepping up to 60A when your pack's thermal management is doing its job. The 180A pulse rating gives you a substantial buffer for the hard current spikes that come with motors, drivetrains, and high-power tools. An AC internal resistance of ≤4mΩ keeps voltage sag tight under load, and the wide discharge temperature range of -20°C to 80°C means it stays dependable across real-world conditions. With up to 600 rated cycles at ≥60% capacity, the JP50 is a cell you can build around for the long term. Use it in a properly designed pack with a BMS rated to match what this cell can deliver — it will reward you for the effort.
Applications / Uses
- E-bikes and electric vehicle packs where sustained current and long cycle life are both priorities
- FPV drones and RC vehicles demanding continuous and burst current for competitive performance
- Heavy-duty cordless power tools and industrial equipment requiring reliable 60A output
- Robotics and high-current automation builds that can't afford voltage sag mid-operation
- Custom high-performance battery packs, energy storage systems, and high-output flashlights
