Hello all, I am planning to move my battery to a pannier position and as such need to extend the connector cable. I recently purchased an M12 4 Pin Extension cable but on receipt the actual 4 Pin Connector is too small to connect to my current cable. I have attached a very poor picture of the current connector which is approx (poor eyesight !) 12mm Diameter. Could you please advise what size / name of connector I need ?. Attached Pics are 1) the type of bottle battery I have and 2) the connector I want to extend.Also if anyone could advise of a company / linky to a firm that makes up these cables ?. Thanks for looking
