Please CONTACT US for availability and compatibility. There is free shipping on these batteries. This battery is larger diameter at the top but has the same exact mounting as its lower Ah counterparts for the Reention Dorado 505L mount. 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 that there are 2 different lengths of Dorado cases. This version of the battery is 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. The ID-21700 version also sits 5mm taller than the original dorado batteries (Plus/Max) so please check clearance of your bike’s top tube before buying. 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 are looking for a lower range version please see Reention Dorado 48V 20Ah MAX Battery or for 15.5″ version please see Reention Dorado 48V 20Ah Battery.
