Varstrom 52V 20Ah Ebike Battery Review: Is It Worth It for Your Electric Bike?

The Varstrom 52V 20Ah battery is a powerful replacement or upgrade battery for people who already have an electric bike or are building one from a kit. With 1040 watt-hours of energy storage, this battery can take you much farther than smaller batteries. It works with motors from 500 watts up to 1500 watts, which means it fits many different e-bike setups. The battery has a lock built in to stop people from stealing it, and little LED lights that tell you when you need to charge it. It comes with everything you need including the charger and mounting bracket that attaches to your bike's water bottle holes.

This battery is perfect for people who want to make their e-bike go farther between charges or who are building their own e-bike from a conversion kit. If you ride to work every day or take long weekend rides, the big 1040Wh capacity means you won't run out of power as quickly. The price of $330 is really good compared to other batteries this big - you're getting a lot of power for your money. It will last about 5 years and can be charged over 1000 times, so you won't need to replace it for a long time. The battery has special safety features with dual protection systems and fuses on each cell to keep you safe.

However, remember this is only a battery - you can't ride it by itself. You need to already have an e-bike or buy a motor kit separately to make a complete electric bike. The battery is also pretty large at about 14.5 inches long, so it might not fit smaller bike frames. You only get 30 days to return it if something goes wrong, which is less time than some other companies give you. The battery uses an XT60 plug, so you'll need to make sure your motor kit uses the same type of plug or get an adapter. If you're looking for a complete ready-to-ride e-bike, this isn't what you want - but if you need a strong, long-lasting battery for your existing bike or DIY project, this is a solid choice.
