Price
18650 batteries are commodity cells, and as a wholesaler, we understand how important price is to your bottom-line. As such, we offer international shipping directly from Asia to save money in higher quantities.

Quality guarantee
Battery Bro values long-term relationships with clients and encourage our clients to performance test cells against official manufacturer specification sheets.
In Asia, 18650 batteries are binned by quality into A, B, and lower bins. C-bin batteries are often recycled from battery packs. Lower bin batteries will underperform and may be dangerous.
We will only provide A Grade cells, unless specifically required to otherwise, for example, some clients may prefer Grade B Chinese cells for low-cost ESS projects. We can also confirm batch-date code, run testing (like impedance/voltage/capacity), and handle other IQC requirements.
Note: Loose cells are not authorized or intended to be used as stand-alone, removable, rechargeable power sources for e-cigarette or vaping devices, or to be handled directly by consumers in any manner. Clients who inquire about loose cells must intend to manufacture battery packs with proper outer casing, PCM/BMS, and protection functions and be able to provide documents to prove this.
