Samsung 30T 21700 3000mAh 35A Battery

When your application requires high current without overheating or severe voltage drop, the Samsung 30T delivers. Unlike standard high-capacity cells that struggle under load, the 30T is a "Power Cell" designed to maintain stability even when pushed to its 35A limit.

Why Choose the Samsung 30T?

Extreme Output Capability: With a massive 35A Max Continuous Discharge, this battery is built to drive high-torque motors and demanding electronics. Whether you are building a custom battery pack for an electric skateboard or powering industrial tools, the 30T ensures your device receives the current it needs to perform at peak efficiency.

Superior Thermal Management: The 21700 form factor offers a significant advantage over older 18650 cells. The larger surface area and advanced internal chemistry allow the 30T to run cooler under heavy loads, extending the lifespan of the cell and the safety of your device.

 

Battery Safety Notice

Your safety is our priority. These are high-performance unprotected cells.

  • Never carry loose batteries in your pocket with keys or change (use a plastic case).
  • Always inspect your battery wraps for tears before use.
  • Do not exceed the CDR (Continuous Discharge Rating) of the battery.

AWESOME BATTERIES... HIGHLY RECOMMEND THEM!

Tihs is actually my first time using 21700 batteries, but I just recently bought a SMOK FORTIS which can use both the 18650 battereis and the 21700, so after reading reviews and the claims of a longer lasting charge, I decided to buy 2 of the SAMSUNG 30T 21700 3000MAH 35A BATTERIES... I'm so glad that I did and holy cow, they really last a long time between charges. Highly recomment them.
