Designing the Wistiki with a hatch to replace battery and at the same time avoid all water infiltration has been a big challenge during the conception phase of the Wistiki.
The Wistiki has therefore been conceived to :
-be rain resistant
-resist a 50kg (11 Ib) load (when battery is loaded in the Wistiki)
Thus, the 100% French manufacturing of the Wistiki gives birth to a top quality product, resistant to everyday environmental conditions.
Note : the Wistiki does not resist to extended immersion in liquid.
