This blog post is a detailed review of the Watt Cycle 314Ah Mini LiFePO4 batteries by a sailboat owner preparing for an Atlantic crossing. The author upgraded from a 440Ah AGM battery bank to a 628Ah LiFePO4 system using two Watt Cycle batteries in parallel.

This blog post explains the key differences between deep cycle and dual-purpose batteries, with a focus on their applications in motorhomes.

• Deep Cycle Batteries: These are designed to provide a steady, consistent power supply over long periods. They are ideal for running appliances like refrigerators, water pumps, and lights when you are off-grid. A key feature is their ability to be deeply discharged (down to 80-90% of their capacity) without being damaged.
• Dual-Purpose Batteries: Also known as cranking batteries, these are designed to deliver a powerful burst of energy to start an engine. While they can also power some accessories, they are essentially a compromise between a starter battery and a deep cycle battery.

The article recommends deep cycle batteries for those who spend a lot of time off-grid and have high power demands for their appliances. Dual-purpose batteries are better suited for shorter trips with frequent engine starts and lower power needs for accessories. The post also highlights the advantages of LiFePO4 (Lithium Iron Phosphate) batteries, which are lightweight, have a longer lifespan, and are maintenance-free compared to traditional lead-acid or AGM batteries.

Yes — many jurisdictions require navigation lights for night voyages; even where enforcement is light, lights are essential for visibility and avoiding collisions after dark.

Looking to power your motorhome off-grid with confidence? Discover how to design a dependable system using lithium batteries—from calculating power needs to wiring safely. This guide walks you through every step to build a lightweight, efficient, and long-lasting setup with WattCycle LiFePO4 batteries.

A comprehensive comparison between LiFePO4 and lead-acid battery, learn about the differences between LiFePO4 batteries and lead-acid batteries in terms of weight, size, cycle times, lifespan, monitoring, and maintenance.

Hi, I'm Paul Mooney - Admin from Self Built Campervans group on Facebook with 90,000 subscribed members. I have been camping and campervanning for approximately 20 years. I decided to build my own Self Built Campervan 5 years ago as factory-priced motorhomes and campervans are very expensive. We absolutely love the feeling of freedom it gives me and my family. I have travelled extensively throughout Europe and enjoyed every minute...

Gerold K., a long-time campervan user from Germany, planned to upgrade his new campervan's standard battery to a LiFePO4 battery this past January. He stated that his previous campervan used expensive starter batteries. However, after conducting research, he became convinced that WattCycle offers an attractive and cost-effective alternative to lead-acid batteries. In January, my wife and I were presented with our new motorhome - a Giottiline 322 - by the...

Bart C., a loyal customer from the Netherlands, had been searching for the ideal battery solution for his RV — a Carthago Chic C-line 6.2 XL QB — since late October 2024. While he acknowledged the strong market preference for S.B. batteries in the Netherlands, their premium pricing—over four times the cost of WattCycle's comparable offerings—gave him pause. Though initially hesitant, Bart ultimately chose WattCycle — a decision he now...
