Please CONTACT US for availability and pricing. 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 440L mount. Compatible with many brands like Surface604, Quietkat, iGo, 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 15.5″ tip to tail (called the 440L) where as the larger version is 18″ tip to tail (called the 505L). The 505L mounting system is not compatible as it is too long. 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 do have the 18″ version please see Reention Dorado 48V 20Ah MAX BatteryReention Dorado 48V 25Ah 21700 Battery. We also have the the Dorado Locking Mount and Key.
