Thereby, both the main power cable sizes as well as the available battery capacity is important. It is the actual delivered voltage at the thruster when it is running, after the voltage drop both in the batteries as well as through the cables, main switch and fuse, that decides the actual power of the electric motor and thereby the possible thrust. So, getting this right will be important for your product satisfaction. It is also important to remember that different types of batteries have different capabilities and specialties, and what is important for thrusters is the cranking capacity, the batteries ability to deliver a high current for a shorter period of time.\u003c\/p\u003e\u003cp\u003eOur Part # SIDSM15112N | Side-Power (Sleipner) Part # SM15112N\u003c\/p\u003e","brand":"Sleipner","offers":[{"title":"Default Title","offer_id":49349044142386,"sku":"SIDSM15112N","price":2143.35,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0879\/4908\/2930\/files\/SIDSM15112N.jpg?v=1735913980"}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0879\/4908\/2930\/collections\/SIDSM10112N.jpg?v=1793121594","url":"https:\/\/www.mauripro.com\/collections\/owners-manuals-sleipner-voltage-conversion-box-10112a.oembed","provider":"MAURIPRO Sailing","version":"1.0","type":"link"}
