Power!
Premium 12.8V lithium iron phosphate batteries manufactured to our specification and individually tested in the UK. Engineered for canal boats, marine vessels, campervans, and off-grid living with built-in Bluetooth monitoring.
Lithium Iron Phosphate represents the pinnacle of battery technology for marine and off-grid applications. Here's how it compares.
Whether you're cruising the canals, wild camping, or living off-grid, DS4A batteries deliver reliable power when and where you need it.
Use 100% of your capacity without damage. Lead-acid can only safely use 50%, meaning you need twice the battery bank.
Charge at up to 200A. Get back to full charge faster from solar, alternator, or shore power.
Built-in heating system activates automatically below +5°C for safe cold weather charging. Discharge from -20°C to +60°C â perfect for UK winters.
LiFePO4 is the safest lithium chemistry â superior thermal and chemical stability with tested protection against short circuit, overcharge, and over-discharge.
Our dedicated Android app lets you monitor voltage, current, temperature, and state of charge in real-time via Bluetooth.
Connect multiple batteries in parallel to increase capacity. Easily scale your system as needs grow.
50% lighter than lead-acid equivalents. Crucial weight savings for boats and mobile applications.
Manufactured to our specification by a leading global supplier. Every battery individually tested and QC'd in the UK.
