New! Upgrade to the Samsung 25R Deluxe Pack
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.

II. Only GRADE A cells
- Grade A: Batteries perform to manufacturer specifications.
