      PP3 9V USB LITHIUM RECHARGEABLE BATTERIES

      Banggood (China) have PP3 9v/400 and 800  milliamp   RECCHARGEABLE LITHIUM batteries available ,that can be charged by a special mini USB cable (available from Bangood) from your lappy or PC.

      Bit dearer than the usual rechargeable types.  AlieExpress have them cheaper I noticed..not much cheaper.  USB cables  available  to charge 1, 2 3 or 4 batteries the same time from the one source.  Batteries indicate when charged and are fitted with the safety PCB.  Connections by the usual PP3 type.

      AlieExpress do not appear to have the charging cables.

      How about a link? banggood search gives 0 results for pp3 rechargeable lithium, and 9v rechargeable lithium.

      Clearly a special cable, since USB is 5 volts

      Thanks for the info Ross, I've been thinking about these. Only problem, signed up to the site and all those batteries are out of stock and some with no re-stock date. Tried AlieExpress but can't get anything but the home page to load.  Not a criticism just what I'm seeing right now.

      Their offer of 2 batteries is out of stock..Singles still available and there are two makes  to choose from.  However...I wanted a couple and had to buy them from AlieExpress at a priced pair AND  they were slightly cheaper.... 

       

      TRY THIS..

      Interesting, found a video of what is inside, two 3.7v cells, with a DC-DC converter to boost to close to 9v, although some people have measured these at 8.13 volts.
