⚠️ Safety Warning for Lithium-Ion Battery Usage
This cell is a rechargeable lithium-ion battery. Mishandling, short-circuiting, overheating, overcharging, puncture, crushing, or physical damage can cause fire, burns, or serious injury.
The Samsung 30Q should be used in a properly engineered battery pack or host device with over-charge, over-discharge, over-current, over-heat, and short-circuit protection. Charge with a CC/CV charger only, and monitor temperature during charge and discharge.
Important Usage Guidelines:
- Use in a Properly Protected Battery Pack / Host Device
- Charge with a Correct CC/CV Lithium-Ion Charger
- Monitor Temperature During Charge and Discharge
- Spot Weld Only – Do Not Solder Directly
- Do Not Use if Wrap or Insulator Is Damaged
- Prevent Shorts – Keep Away from Loose Metal Objects
- Do Not Overcharge, Over-Discharge, Crush, Puncture, or Burn

Let customers speak for us
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!
