Ampace JP50 21700 Cell – 5000mAh 60A – High-Power Lithium-Ion Battery - Check availability
Continuous discharge: 40A
The Ampace JP50 21700 5000mAh is a high-power lithium-ion cell engineered for very low internal resistance, strong current delivery, and stable thermal performance in demanding battery pack applications.
With a 5000mAh mean capacity, 4900mAh minimum capacity, 3.58V nominal voltage, and up to 60A continuous discharge capability with 80°C thermal cutoff, this cell is well suited for high-performance battery packs, e-bikes, power tools, robotics, drones, EV systems, and other engineered high-current applications.
This cell uses a flat top 21700 format and is intended for properly designed battery packs with BMS protection and thermal management. It is best suited for users who need both strong runtime and serious power output in a modern high-drain cylindrical cell.

⚠️ Safety Warning for Lithium-Ion Battery Usage
Customers should understand proper lithium-ion battery handling before use. These cells can present fire, burn, or explosion hazards if short-circuited, overcharged, physically damaged, overheated, or used outside manufacturer specifications. Always charge on a fire-resistant surface and never leave charging batteries unattended.
By purchasing or using this battery, the user assumes responsibility for correct handling, pack integration, charging, thermal control, and protection. This cell is best used in a protected battery pack with an appropriate BMS/PCB and temperature management. Only use chargers and charging methods designed for this battery type, and never mix old and new cells in the same pack.
Important Usage Guidelines:
- Not for Use in E-Cigarettes or Similar Devices
- Must Be Used in a Protected Pack
- Use Thermal Management for High-Current Operation
- Spot Weld Only – Do Not Solder Directly
- Store in Fireproof Container
- Inspect Before Use
- Follow Manufacturer Specs Strictly
Orders ship from Florida when inventory is available. Lithium-ion cells require proper handling, protected packs, correct chargers, and safe storage. Do not solder directly to battery terminals.

Wow, these cells are great!
I purchased some of these tabless cells to try on my 1S 3" HD Toothpick drone build, and, albeit a bit heavy for 1S, it flies pretty well. Not a freestyle monster, but an endurance beast with decent send. These cells shrug off the demands of a BETAFPV Matrix HD AIO flight controller/12A ESC and some 1202.5 11000KV motors. I'm getting 15+ minutes of speedy flight time from a single cell trying not to go below 3.2V, and about 20+ minutes cruising. Love these cells and will definitely buy more when time comes, only from DIY500AMP, who are terrific!
