Victron LiFePO4 Battery 25.6V 100Ah NG | BAT524110620

The Victron LiFePO4 Battery 25.6V 100Ah NG is a lithium iron phosphate battery for off-grid, marine and backup power systems. Part of Victron's NG (New Generation) range, it holds 2.56kWh of usable energy at 25.6V nominal and is designed to work within Victron's managed BMS architecture rather than as a standalone lead-acid replacement.

Product overview

LiFePO4 cells tolerate deep cycling without the degradation seen in lead-acid alternatives, and don't need the same float maintenance regime. This 25.6V configuration suits 24V systems common in marine, vehicle and mid-scale off-grid installs.

A compatible Victron Battery Management System is required to manage over-charge, over-discharge and over-temperature protection. This is not a drop-in swap for lead-acid without the correct BMS and charger set-up, so installers should confirm compatibility before specifying it. At 18.5kg it's manageable for one person to fit in most cases; take care in confined or overhead mounting positions. Multiple units can be paralleled to expand capacity, following Victron's published guidance for the NG series.

Applications

Used in 24V off-grid solar storage, marine and narrowboat house banks, motorhome auxiliary power, and UPS or backup systems specifying lithium. Also used to expand existing Victron NG battery banks in parallel.

Installation notes

This battery must be installed with a compatible Victron BMS by a qualified installer experienced with lithium systems. Incorrect wiring or an absent BMS can damage cells or create a safety hazard. Marine installations should be mounted securely and ventilated per the vessel's electrical standards; grid-connected or PV installs in the UK should be checked by an MCS-accredited installer.
