Buy a freestyle wave board around 90 litres. For WA is the most versatile, and at your weight the 113 is the limiting factor in your progression, you can keep it for light wind.
Put very simply you dont need to discharge and recharge, just need to keep it charged. Keep in mind that when you put it on the charger it might detect more voltage and show 3 green flashes, but in reality the battery is not fully charged.
