Please CONTACT US for compatibility. There is free shipping on these batteries. This battery is a larger diameter at the top but has the same exact mounting as its lower Ah counterparts. Compatible with many brands like Surface604, iGo, Rad Power, Pace. Gio, Biktrix, e-Joe, Volt Bike, Samson, Juiced, Rize, NCM Moscow, Smartmotion, FLX, and many more. There should be no need to change anything with your current mounting system if you do have a compatible bike.


Note: There are 2 different lengths of Dorado cases. This version of the battery is closer to 18″ tip to tail (called the 505L) where as the smaller version is 15.5″ tip to tail (called the 440L). The 440L mounting system is not compatible as it is too short. If you have viewed the images below and are still unsure of if this battery is compatible with your E-bike, please CONTACT US as we are happy to help! If you want a bit more range see the Reention Dorado 48V 25Ah 21700 Battery or for the shorter Reention Dorado 48V 20Ah 21700 Battery 15.5″ version may be what you’re looking for.
