Only the best, authentic, wholesale 18650 battery.

Why did we create Battery Bro?

A warning about counterfeit 18650 battery suppliers: A significant number of all lithium ion batteries for sale are fake and potentially dangerous, even from well-known sources. Battery Bro solves this problem by providing only verified, tested, and authentic, lithium-ion batteries direct from reputable manufacturers. We found a need for safe, high-quality, wholesale lithium-ion batteries, and that's what we are here to provide.

What is Battery Bro?

  • An American team based in Hong Kong and California, USA.
  • Wholesaler of only authentic, tested, Grade A cells.
  • Focused on honesty, and transparency.
  • Provides custom engineering for battery packs & capacity to supply large 100,000+ cell orders worldwide.

Battery Bro only stocks authentic li-ion 18650 batteries that are safe for use in:

  • Electric vehicles
  • Laptops
  • E-cigarettes, Vaporizers, & MODs
  • Flashlights, R/C Cars, Power Tools
  • And more...

All batteries are verified and tested and guaranteed genuine before shipping.

II. Only GRADE A cells

  • Grade A: Batteries perform to manufacturer specifications.
  • Grade B: Batteries under-perform or have other defects.
  • Grade C: Batteries are used, repackaged, salvaged, or damaged.

Manufacturers bin their batteries. The A bin is reserved and difficult to obtain. Battery Bro only cells Grade A cells. Many online suppliers, especially those in China, sell Grade B cells or lower and do not tell their customers.

    "The batteries are excellent. Exactly the quality I would expect from a major player like Samsung. The battery case is of excellent quality, and the microfiber cloth is a very nice touch."
