Xiseny 48V10.4ah Folding Electric Bike Battery Review: Does It Deliver Safe, Long-Lasting Power?

This Xiseny product is a replacement battery for electric bikes, not a complete bike you can ride. It's like buying a new battery for your phone or laptop when the old one wears out. The battery holds 499 watt-hours of power, which is okay but not amazing. It weighs 7.7 pounds and can work with bike motors from 200 watts up to 1000 watts, making it fit many different bike brands like ESKUTE, Jasion, and Heybike. The battery has smart safety features that protect it from charging too much, running out completely, or getting hurt by power surges. It can be charged and used 1000 times before it starts to lose power, and even then it still keeps 78% of its strength.

This battery is best for people who already own an electric bike and need a new battery because their old one died or doesn't hold a charge anymore. It works well if you have one of the brands mentioned and need the exact size and plug type that matches. The price of $175 is reasonable for a replacement battery with these features. The company says they'll answer questions within 24 hours if you need help. The battery is approved by safety groups in Europe (CE and ROHS certifications) and has passed short circuit and capacity tests.

However, you should know this battery only has 2 reviews and a 3-star rating, which means not many people have bought it yet and the few who did gave it average marks. You must check that your bike needs this exact size (430mm long, 100mm wide, 40mm tall) and uses a 5-pin plug before ordering, or it won't fit. The 499 watt-hours means you'll get a medium amount of riding distance, not super long trips. If you need a replacement battery and your bike matches these specs, this could work. But if you're looking for a complete electric bike to ride, you need to look at actual bikes instead of just battery parts.
