At 18650.UK, we’re constantly expanding the boundaries of what customers expect from a wholesale battery supplier. We understand how much of a struggle it can be to get cells at a reasonable cost and speed and the frustrating balance between paying over the odds or waiting. With 18650 UK wholesale, you dont have to worry about either. Simply fill out the registration form below and we’ll sort the rest!

We keep stock of all of the most popular 18650 batteries in our UK warehouse, ready for same day shipping on orders placed before 2pm Monday-Friday and they’re delivered the next working day. We too were once very small, and so our minimum wholesale battery order quantity is just 20 cells.

Cell Sourcing

At 18650.UK, our wholesale service goes beyond just what we have on the shelf.

We have fantastic suppliers based strategically around the world, able to source almost any cell, in any size, button or flat top! This includes but isn’t limited to 10440, 14500, 14650, 16340, 17500, 17670, 18350, 18500, 18650, 18700, 26650, 20700, 21700, and 32650 cells and associated chargers. We can also source the components required to build battery packs (spacers, nickel weld strips etc).

Due to the nature of the lithium cell market this isn’t always particularly fast, but the price breaks available for doing so often outweigh this so for those who can forecast their needs, the increase in margin can often be significant. Our average lead time for non stock cells (but available at our suppliers) is around 10 days.

Something bespoke? 

With a network of best in class manufacturers around the world, we can have battery packs manufactured to your spec. If you cant find the pack size or series/parallel configuration your need or if you need it built to a specific shape, we can help. Drop us an email to discuss options on custom battery packs.

A few things to note when purchasing from us;

Our “cells only” option come in wholesale crates of 50 (Sony) or 100 (Samsung, LG) and are not individually packaged or “retail ready”. When ordering less than 100, we break these cases down into custom made smaller, double wall secure boxes. Many of our wholesale customers already have their own branded cases, however we can supply very inexpensive dual 18650 clear cases with your order if required. We do also offer a Retail Ready service with full compliance marking, packaged in a dual or single 18650 cases and inside our custom plain white cardboard box with printed safety information.

MSDS – We hold Material Safety Data Sheets for all of the cells we retail/wholesale. If you need these, please let us know. We supply them at no cost either via email, or in hard copy with your order.
