Reliable 60V Power for EV Builds

The SMALL DEN 60V 18650 or 21700 Lithium Battery Pack is a compact, high-output Li-ion solution for electric motorcycles, tricycles, scooters, and DIY electric projects. Each pack includes a built-in BMS for protection and safer operation under normal use.

Choose the capacity that matches your range needs—10Ah to 30Ah—while keeping a consistent 60V platform.

Key Features

• Multiple capacity options: 10Ah / 12Ah / 15Ah / 18Ah / 21Ah / 24Ah / 27Ah / 30Ah

• 18650 or 21700 Li-ion cells  (depends on the build)

• Built-in BMS protection

• 30A continuous discharge (rated)

• Up to 60A max discharge

• 67.2V charge voltage (60V nominal system)

Technical Specifications

Charger selection:

• <15Ah: 67.2V 3A charger

• ≥15Ah: 67.2V 5A charger

Note (important):  “Voltage: Peak – 60V, working – 67.2V”. Typically it’s 60V nominal and 67.2V full charge. I formatted it the correct way above to avoid confusing customers.
