Reliance RH60 21700 Cell – 6000mAh – High-Energy / Hybrid Lithium-Ion Battery - Check availability
Continuous discharge: 30A
The Reliance RH60 21700 6000mAh is a high-energy / hybrid lithium-ion cell built for applications that need long runtime with stronger discharge capability than a typical energy cell.
With 6000mAh nominal capacity (5850mAh minimum), 3.60V nominal voltage, and up to 30A continuous discharge with 80°C temperature cut-off in the latest F3 specification, this cell is well suited for e-bike packs, power tools, garden tools, portable energy storage, robotics, and other long-range battery builds.
Reliance positions the RH60 as a 21700 high-energy cell with wide operating temperature capability and tabless design advantages. It is best used in properly engineered battery packs or host devices with suitable protection and temperature monitoring.

⚠️ 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 RH60 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. Cell temperature should be monitored during charge and discharge.
Important Usage Guidelines:
- Use in a Properly Protected Battery Pack / Host Device
- 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
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!
