{"id":419,"count":163,"description":"A battery charger connected to the 220 V mains supply is the charging source that ensures the battery bank is fully charged when the sun and the alternator are not enough. Whether in a campervan, on a boat, in an off-grid installation or as a backup system, it is the component that prevents a couple of cloudy days from leaving you without power.\n\nWhich charger do I need?\nTwo decisions: voltage and amperage.\nThe <strong>tension<\/strong> Your bank\u2019s brand: <a href=\"\/en\/product-category\/battery-chargers\/12-v-battery-charger\/\">12V<\/a> in motorhome and recreational boating, <a href=\"\/en\/product-category\/battery-chargers\/battery-charger-24-v\/\">24V<\/a> in motorhomes and medium-sized facilities, <a href=\"\/en\/product-category\/battery-chargers\/48-v-battery-charger\/\">48V<\/a> in a detached house.\nThe <strong>amperage<\/strong> It is calculated as between 10 and 20 % of the battery pack\u2019s capacity. For 200 Ah, this is between 20 and 40 A. With lithium, you can go higher without any problem as it can handle high currents; with lead-acid, it\u2019s best not to exceed this limit.\n\nCharging from the alternator: a mains charger won\u2019t do\nIf you want to charge whilst driving, what you need is a <a href=\"\/en\/product-category\/battery-chargers\/converters\/\">DC-DC converter or booster<\/a>, not a 220 V charger. The booster raises the alternator\u2019s voltage to the level required by the service battery and limits the current to prevent damage to the alternator \u2013 something that is essential for lithium battery packs and the smart alternators fitted to almost all vehicles since 2015.\n\nThe charging profile matters more than the brand\nLithium, AGM, gel and open-lead batteries require different absorption and float voltages. Charging with the wrong profile won\u2019t cause any immediate damage, but it leaves the battery undercharged and significantly shortens its lifespan.\nAll the chargers we supply allow you to select the profile, and the Blue Smart range from <a href=\"\/en\/brand\/victron\/\">Victron<\/a> It is controlled via a mobile phone using Bluetooth, with a temperature sensor to adjust the voltage between winter and summer.\n\nDegree of protection depending on use\nIn vehicles or boats, there is vibration, humidity and salt: that\u2019s where the IP65 and IP67 models come in. For a fixed installation inside a cupboard, an IP22 is sufficient and more economical.\nIf your setup combines the mains, an alternator and solar panels, all three power sources can be connected to the same power bank provided they share the same load profile.
