Bought this to replace a failing Unit Pack Power unit. The Eifduhp feels much sturdier and the range on my daily commute has improved significantly. The included baseplate was a doddle to fit.
Excellent value for money. I use my bike for food delivery and needed a reliable second battery. This lasts my whole shift and charges perfectly overnight.
Great battery, solid build. It's a bit heavier than my old 10Ah one, but the extra miles make it worth the weight. Fast delivery to Bristol too.
Finally, a seller that provides clear compatibility info. I was worried about the connectors, but the description was spot on. Highly recommend for any DIY e-bike builder.
As a daily commuter, safety is my priority. Knowing this has a proper BMS and UK certification gives me peace of mind while charging in my hallway.
Good performance so far. The lock is a bit stiff at first, but after a bit of use, it's fine. Much better range than the stock battery that came with my bike.
Founded by a team of electric vehicle enthusiasts in the heart of the UK, Eifduhp Power was born from a simple frustration: the lack of reliable, affordable replacement batteries for the growing community of British e-bike commuters and leisure riders. We understood that a battery isn't just a component; it's the heart of your journey, whether you're navigating the hills of the Peak District or the busy streets of London.
At Eifduhp, safety is our non-negotiable priority. Every battery we supply undergoes rigorous quality control and is equipped with an advanced Battery Management System (BMS) to protect against overcharging, overheating, and short circuits. We don't just sell batteries; we provide the peace of mind that comes with UK-based technical support and a comprehensive warranty.
Our mission is to extend the life of your electric bike. By offering complete kits that include the charger and mounting baseplate, we make the upgrade or replacement process seamless for everyone from delivery riders to weekend adventurers. We are committed to powering a greener Britain, one charge at a time.
Our products are designed and supported in the UK, ensuring superior quality and fast tracked delivery from our British warehouse. We offer free UK delivery on all orders, eco-friendly packaging to reduce carbon footprint, and warm, direct customer service. Every order is backed by a generous 30-day returns policy under the UK Consumer Rights Act 2015 — you are always protected.
