Swapped out the four heavy lead-acid blocks on my electric moped for this single 20Ah unit. The weight difference is incredible-handling is so much sharper, and the acceleration is noticeably punchier.
I use my e-scooter for daily commuting, and range anxiety was becoming an issue. Since installing the SDTYYP battery, I easily get double the range I used to. The built-in BMS gives me great peace of mind when charging indoors.
Brilliant battery with excellent power delivery. My only minor gripe is that the dimensions were a very tight squeeze for my specific custom frame, but once it was in, it performed flawlessly.
As an engineer, I appreciate the transparency of the specs. The continuous 30A discharge is exactly as advertised, and the build quality of the ABS casing is far superior to the cheaper imports I've tested previously.
I was looking at Unit Pack Power but decided to go with SDTYYP for the UK warranty and support. Very glad I did. The delivery was next-day, and the battery has completely revived my old electric bike.
Bought this to retrofit my 48V electric lawn mower project. It works perfectly and holds a charge for weeks in the shed. Deducted one star just because I had to buy the lithium charger separately, but otherwise a fantastic bit of kit.
Founded with a passion for electric mobility and practical power solutions, SDTYYP Battery UK was born out of frustration with the heavy, short-lived lead-acid batteries dominating the market. We saw riders and DIY repairers struggling with sluggish performance and constant replacements, and we knew there had to be a better way.
Our mission is simple: to provide high-discharge, rigorously tested 20Ah lithium batteries that transform the way you power your equipment. Whether you are reviving an electric moped, extending the range of a high-capacity e-scooter, or upgrading heavy-duty utility gear, our batteries are engineered for the demands of the British climate and roads.
Unlike generic imports, every SDTYYP battery features an advanced built-in Battery Management System (BMS) to protect against overcharging and short circuits. Backed by full UKCA and CE certifications, UN38.3 transport testing, and a dedicated UK support team, we deliver the peace of mind that brands like Unit Pack Power often overlook. Ride further, carry less weight, and power your journey with confidence.
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.
