Step up your campervan conversion with the LB400-HD Lithium Iron Phosphate battery. Lighter, tougher, and built to outlast lead acid, this 400Ah unit delivers serious power for off-grid van life. Whether you’re running a big inverter or stacking appliances, it keeps the energy flowing without weighing you down.

Benefits:
• Power hungry gear with a solid 300A discharge.
• Built-in Current Shunt for accurate state of charge tracking.
• Outlasts AGM batteries with up to double the lifespan.
• Perfect for campervan conversion projects needing high capacity.
• Saves weight compared to bulky lead acid setups.

Features:
This 400Ah LiFePO4 battery is designed for demanding off-grid setups where reliability counts. It packs a hefty 300A continuous discharge, enough to comfortably run a 3000W inverter for cooking gear, fridges, or work tools. A built-in Current Shunt gives you precise State of Charge monitoring so you always know how much juice is left. When it’s time to park up for a while, the integrated Battery Switch lets you isolate the system for safe storage. Plus, Communication Ports allow seamless integration with other devices for smarter energy management. Compared to premium AGM batteries, you’ll get double the lifespan and significantly reduced weight, making this a practical choice for serious van builds.

People are asking

Why choose a 400Ah lithium battery for a campervan?

A 400Ah lithium battery provides a large usable capacity — roughly 400-480Ah of actual usable energy at 100% depth of discharge, compared to about 200Ah usable from a 400Ah lead-acid battery. This enables multiple days of off-grid use running a fridge, lighting, laptop, and other appliances without solar input.

Is the Projecta 400Ah battery compatible with the PM335C charger?

Yes. The Projecta PM335C Intelli-RV Gen II system is designed to work with Projecta lithium batteries and includes lithium charge profiles. This makes them a natural pairing for a fully integrated Projecta power system in a campervan build.

How long does the Projecta 400Ah lithium battery last?

LiFePO4 lithium batteries are rated for 2000-3000+ charge cycles, significantly longer than lead-acid batteries at 300-500 cycles. With typical campervan use of 1-3 cycles per week, a lithium battery should last 15-30+ years of service life before significant capacity degradation.
