Lead-acid chemistries including AGM, gel and flooded batteries are all supported.\u003c\/p\u003e\u003cp\u003eThe adaptive charge algorithm adjusts absorption time based on the previous discharge, cutting unnecessary gassing and helping battery life. Storage mode drops the voltage to a low maintenance level when a battery sits connected without cycling for long periods. The (1) designation refers to the unit's parallel output configuration, allowing two Skylla-TG 48\/25 units to be combined for higher charge current.\u003c\/p\u003e\u003ch2\u003eApplications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eOff-grid 48V battery banks needing high-current charging.\u003c\/li\u003e\n\u003cli\u003eMarine vessels with 48V house battery systems on shore power or generator supply.\u003c\/li\u003e\n\u003cli\u003eIndustrial and telecoms backup power installations.\u003c\/li\u003e\n\u003cli\u003eGenerator-fed charging where AC input quality is inconsistent.\u003c\/li\u003e\n\u003cli\u003eParallel charging with a second Skylla-TG 48\/25 unit for increased output.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWhat's in the box\u003c\/h2\u003e\u003cul\u003e\u003cli\u003e1x Victron Skylla-TG 48\/25(1) 230V battery charger\u003c\/li\u003e\u003c\/ul\u003e\u003ch2\u003eInstallation notes\u003c\/h2\u003e\u003cp\u003eInstall with a qualified electrician, in line with current wiring regulations (BS 7671 in the UK) and any applicable marine electrical standards.
