I have had several emails from Nevo Q50 owners here, asking if I had replacement batteries.
I have just added the original factory battery to our website at http://www.Prontowizard.com
For now, I have a small supply on hand. I will try and increase stock if there are sufficient orders.
These are factory original batteries (which are impossible to find) and are ready to plug in, no modifications required. We ship world-wide.
The battery purchase includes an instant .pdf download of our custom illustrated installation instructions which are quite significant as the unit requires dissasembly to change the battery.
Drop me an email if you have questions or any trouble with ordering since it is a newly-added product at our site.
