Lithium LiFePO4 Batteries

Lithium LiFePO4 batteries and the components that manage them give an RV or off-grid system more usable capacity and faster charging than lead-acid. This collection covers the Victron LiFePO4 NG battery, the Victron Lithium SuperPack drop-in 12.8V and 25.6V batteries, the Victron Smart BMS 12-200 with alternator charging, and smaller pieces like the smallBMS, VE.Bus BMS, and Cyrix battery combiners needed to wire a lithium bank safely.

A lithium bank needs a battery management system sized to your charge sources, so check whether your setup calls for the compact smallBMS, the VE.Bus BMS for MultiPlus systems, or the Smart BMS 12-200 for alternator charging before you order. Ships from Upland, California, with eligible returns subject to our Refund Policy.

How big a lithium battery does my RV need?

Most travel trailers do well with 100Ah to 200Ah at 12V; running an inverter for a microwave or AC pushes that to 280Ah or more. See 100Ah vs 200Ah vs 280Ah, or use the RV solar and battery calculator.

Do I need a new converter or charger for lithium?

Often, yes: many older RV converters never reach full lithium charge voltage. See what has to change for lithium.

Can lithium batteries be charged below freezing?

Standard LiFePO4 batteries must not be charged below about 32°F. For winter camping, choose a self-heating battery, such as LiTime's LiHeat models, or keep the battery inside the heated space.
