A traction (battery with deep cycle) or a semi-traction battery.
Preferably a gel or AGM battery, can also be an acid battery, but it is not advisable for it to tip over in the boat. Ideally of “marine” type = enclosed battery, with no risk of electrolyte or acid gel leakage when tipped over.
Recommended battery capacity is 65-75 Ah, this capacity is enough for a run time of about 2 hours at maximum power or about 5 hours at speed level 3.
Charger
The charger should allow switching between Gel, AGM, and normal batteries or be equipped with a microprocessor for automatic control of the charging cycle depending on the battery type.
