Question about Stx Electric SUP Pump incl. battery

A word of warning: the battery in this pump must be monitored regularly in the off-season. If the charge drops below a certain level, the battery will deteriorate and will no longer hold the charge. Unfortunately, we did not charge ours in the off-season and now the pump can no longer charge. Even a whole paddle. So don't hesitate to charge your pump every 1-2 months if it is not in use. if it is not used.
