Hello, There are 2 different models of this Ledlenser 14500 battery, the one for the MH3-MH4 and MH5 lamps, and the one for the P5R and P5R.2. These batteries differ by the "+" contact, which is raised for the MHx, and flat for the P5R. Which model do you sell, as the picture shows the MHx model, and the description says P5R? Thank you for your answer.
