LiFePO4 Battery

Also known as: LFP battery, lithium iron phosphate, lithium leisure battery

Lithium iron phosphate — the lithium chemistry used in modern leisure batteries, prized for long cycle life, full usable capacity and thermal safety.

LiFePO4 (lithium iron phosphate, sometimes 'LFP') is the lithium chemistry that has become the default for campervan leisure batteries. Compared with lead-acid it delivers almost all of its rated capacity (vs ~50% usable for lead-acid), weighs far less per usable kWh, and lasts thousands of cycles.

Real figures from the UK market show the scale: a Fogstar Drift 12V 105Ah is rated for 3,500+ cycles at 80% depth of discharge with a 10-year warranty, and weighs about 10 kg. The trade-off is cold: most LiFePO4 cells must not be charged below freezing, so winter vans use a self-heating model or keep the battery in the heated habitation space. A built-in BMS (battery management system) protects against over-charge, over-discharge and imbalance.
