Hello, after I always found the battery charging quite cumbersome (decompose the seat bench, connect the charger), I now enjoyed this part and added it yesterday: www.louis.de/…/index.php?… Just connect to the battery and attach the socket somewhere on the mopped (with me on the frame, below the seat bench, freely accessible), is easy, the result convinced. Now I have an external access to the battery, can recharge quickly and on board power a It’s on sale at Aunt Louise’s.
