Rechargeable Battery Set:
A battery kit includes 2 rechargeable battery packs, which can be seen in the photo, are arranged in an arc. When you open the case, you can put the two cables to the existing cable.
Depending on the year of construction, only 1 pack was used. If only 1 pack is required, please indicate this in the comments of your order. Then only € 100.00 will be charged. If you open both covers, you can see whether there is 1 battery pack in each cover (total of 2 battery packs) or only one battery pack in one cover.
