You may have seen some ads here for the product "Booster Battery" for the SONDORS eBikes.
We highly warn against these batteries they are really dangerous. Connecting two different batteries together may/will cause the weaker battery to drain first to the point where voltage becomes zero, at this point the battery will be damaged forever with no way to repair it. That may be fine for some of you but, here comes the dangerous part. The larger battery will continue to draw from the weaker battery which have already been exhausted and it will get extremly hot - a extremly hot and exhausted battery will explode and burst into flames. You are getting yourself and other lives in danger when you're connecting two batteries that are not the same voltage and amp hour. You might have been doing this with no negative effect yet but obviously you have not done long term testing. If it was this simple, someone would have done this along time ago.
Lithium batteries in general are extremly explosive and highly flammable especially when you are not utilizing it properly. Here's a video of what happens when lithium batteries get hot:

The purpose of this thread is to display the various parts of the Sondors Original electric bicycle. These diagrams are meant to annotate all parts on the Sondors Original ebike with an eye towards defining terms for the complete beginner. Have a suggestion for improvement? Post a question in the forum so all can see and contribute. This thread is a reference work that is closed to replies to keep it tidy.
Try clicking on an image and bring it up in a new window. These started out life as high resolution images and can be seen larger in their native format.
Here we point out common terms for the Sondors frame. These terms are common to all bicycles and ebikes, and you can use these terms in any discussion of cycling, anywhere.
Here we list the parts attached to the frame, above. We can't point to every single part but we have hit all of the highlights
Components - Rear
Zooming in on the back to label a few things not easily visible in the full bike view.
Components - Front
Zooming in on the front axle area to see some details on the brakes. More importantly, if someone wants to see your Sondors' nipples you don't necessarily need to call the police.
Components - Middle
Now you know the bottom bracket means two things depending on what you are pointing at. And the 'spindle' is the axle of the cranks, and hold on the crank arm via the crank bolt (which takes an 8mm hex key wrench that you should check every so often to ensure it is still at about 35 ft lbs of torque). Plus with this enlarged view we can see the 2-pieces that make up the PAS system a lot better.
