⚠️ 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, punctured, 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, temperature management, and protection. This cell is best used in a properly designed battery pack with appropriate BMS/PCB protection. 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
- Use in a Properly Protected Pack
- Spot Weld Only – Do Not Solder Directly
- Monitor Temperature During Charging and Discharge
- Inspect Wrap and Insulator Ring 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!
