Reliable Performance for the British Commute
The Eifduhp 48V 13Ah battery is engineered to be the ultimate replacement or spare for your electric bike.

Whether you are tackling urban hills or long-distance canal paths, the 13Ah capacity ensures you have the range to get there and back without range anxiety.
Advanced Safety & BMS Protection
Safety is at the core of our design. This battery features a sophisticated Battery Management System (BMS) that actively monitors every cell. It provides essential protection against over-charging, over-discharging, short circuits, and overheating. Encased in a high-impact, water-resistant housing, it is built to withstand the vibrations of the road and the occasional British downpour.

We've eliminated the guesswork of upgrading your battery. This kit comes complete with a dedicated 2A UK mains charger and a sturdy mounting baseplate. The baseplate easily attaches to standard water bottle bosses on your bike's downtube.

Customer Reviews
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.
Superb service. Had a question about the mounting bolts and the UK support team replied within an hour. The battery itself is top-notch.
