About Us
At Battery King, we do one thing and we do it well: high-quality replacement batteries for e-bikes and e-scooters, delivered free across the UK. Whether your battery has finally worn out or you're after more range, we make it simple to find the right, certified battery for your ride and get back on the road with confidence.
Who we are
We're a UK-based supplier of premium lithium-ion batteries and chargers for electric bikes and scooters. We saw how frustrating and expensive it was for riders to replace a failing battery confusing specs, uncertified imports, and the temptation to scrap a perfectly good bike or scooter. So we built a store focused entirely on making battery replacement easy, safe and affordable.
What we do
We supply certified replacement batteries and chargers for a wide range of e-bikes and e-scooters, covering popular brands and the most common battery formats. From Hailong and Silverfish e-bike batteries to Xiaomi, Kugoo and Aovo scooter batteries, we help riders match the exact battery their machine needs.
