FAQ's

Q: Can I swap my AGM battery with this Custom Lithium unit?
A: Only if your charging setup supports lithium profiles. Chargers must offer compatible bulk (14.2–14.6V) and float (13.4–13.6V) voltages.

Q: What size DC-DC charger should I use?
A: All Victron and Redarc DC-DC chargers sold by us are lithium-compatible. A 40A charger is ideal for faster recharging, while 25A–30A options are slower but still effective.

Q: Are Custom Lithium batteries certified?
A: Yes. All batteries use IEC-62619 certified components and meet AS/NZS 3001 recommendations.
