It connects the batteries during charging and keeps them isolated when discharging, greatly reducing the risk of a flat starter battery.\u003c\/p\u003e\n\u003cp\u003eUnlike a mechanical relay, the Charge Mate Pro limits the charge current to the second battery to 40 A, so the primary battery is always charged with priority. It is unidirectional and blocks the return current under all circumstances, even when the secondary battery sits at a higher voltage, which also prevents power dips on the onboard network. A typical marine use is linking a bow thruster battery to a service battery so the bow battery stays charged.\u003c\/p\u003e\n\u003cp\u003eThe unit suits charging from AGM or GEL starter batteries to AGM, GEL or lithium service batteries, has a very low voltage drop of max 0.2 V and LED status indication. The IP65 electronics sit in a corrosion-resistant casing with aluminium heat sinks. An optional bypass switch enables an emergency start function. For a lithium starter battery, use part 83304004.\u003c\/p\u003e","brand":"Mastervolt","offers":[{"title":"Default Title","offer_id":56282449936724,"sku":"83304002","price":295.38,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0941\/9702\/3060\/files\/M83304002.jpg?v=1782766735","url":"https:\/\/hme.sprechen.dev\/products\/mastervolt-charge-mate-pro-40-split-charge-relay-12v-24v-40a","provider":"Hudson Marine Electronics","version":"1.0","type":"link"}
