What affects my riding time on a single charge?

The riding time is heavily dependent on some key specific things such as: 

• Riders weight - the heavier the rider gets the more power it takes to keep him gliding on the water.
• Water currents or/and waves - Water currents and waves can decrease the total riding time on a single charge.
• Outside temperature - the batteries tend to discharge a bit faster when there's cold outside
• Unbalanced cells - if your battery has unbalanced cells, it will discharge faster than usual. If you see unbalanced cells error, it's recommended to place the battery on the charger until it's fully charged.
