does anyone know what type of battery pack this is (lead, li-?) and where it came from?
there are 9cells and 19cell in series setup. each cell is 7.5v as it - the actual voltage is unknown. 9cells x 7.5v = 67.5v and the 19cells x 7.5v = 142.5V. cells has this qr code and they are serialized - no qr codes are the same. no other p/n to identify it. it's about 70lbs and thinking of lay it on top of the scooter to extend some range. it works out to be 7s4p @48v once re-configured. also what the typical price range for this whole unit or individual cell - once it is identified of course? thanks
side note: i don't' have a picture here but some of the terminals are corroded like the car battery terminals. is this say something about the condition of the pack?
