Quick Overview

The mounting bases for the Dorado batteries are the same, if the length is the same, then you can choose this battery as a spare battery. There are only two lengths for the Dorado cases, L1=458mm or 390mm, some people would like to measure the longest part of the battery, and get 505mm or 440mm to check which model you need to choose. 

There is a 5V USB output for the Dordado case which you can charge your mobile; 

The charging connector will be 5.5x2.1DC or 5.5x2.5DC connector as default; if your original battery uses the mini XLR 3 pin charging connector, you can choose the 3 pin connector for the batteries; normally for plastic chargers or charging current less than 4A, the default charging connector is 5.5x 2.1DC;

For the discharging connecttor, the default connector is 2 pin connector(female PLA0274 and male PLA0273); if your ebike runs larger current, it's better to use 6pin connectors(female PLA 0239 and male PLA 0238); Normally most of the ebikes for power less than 750W will use 2pin connectors.
