12V Lithium Battery Kits for Caravan, RV and 4WD Upgrades

A caravan lithium battery upgrade is one of the most effective ways to extend your time off-grid. This collection brings together two types of 12V lithium battery kits. The first is a range of twin pack Alpha IP67 Smart Bluetooth lithium batteries. The second is a pair of pre-wired lithium battery boxes that combine storage, charging and monitoring in a single unit.

Twin Pack Alpha IP67 Smart Bluetooth Lithium Batteries

Twin packs are available in 50Ah, 100Ah, 180Ah, 200Ah, 300Ah and 400Ah capacities. They suit shoppers building a larger house battery bank or replacing ageing lead-acid batteries in one step. Buying a matched pair from the same range simplifies installation where batteries are wired in parallel to increase usable capacity. Always follow the manufacturer's wiring guidance.

The IP67 rating gives a high level of protection against dust and water ingress. Bluetooth connectivity lets you check battery status from your phone without opening hatches or crawling under beds.

Pre-Wired Lithium Battery Boxes

The 100Ah and 180Ah pre-wired battery boxes integrate three key components with the lithium battery:

• Orion XS DC-DC charger: charges the house battery from your vehicle's alternator while driving.
• SmartSolar MPPT controller: regulates solar input so your panels can top up the battery at camp.
• SmartShunt battery monitor: tracks state of charge, current draw and consumption for accurate energy management.
• Pre-wired construction: reduces installation time and wiring errors compared with sourcing and connecting parts separately.

These lithium battery box kits are well suited to 4WD canopies, campervans and smaller caravans that need a compact, self-contained 12V system. For more complex fit-outs with inverters or larger distribution, compare our pre-wired Victron boards. If you already have a battery and only need charging, browse the charger kits collection.

Choosing the Right Battery Kit

Start with your daily energy use, available mounting space and payload limits. Then decide whether you need storage only or an all-in-one setup with built-in charging. To weigh capacity, weight and chemistry side by side, use our RV and caravan battery comparison tool.

Frequently Asked Questions

Should I buy a twin pack or a pre-wired battery box?

Choose a twin pack if your vehicle already has suitable charging and monitoring, or if you need high capacity. Choose a pre-wired box if you want alternator charging, solar regulation and monitoring included in one unit.

Can the pre-wired boxes charge from solar and my vehicle?

Yes. Each box includes an Orion XS DC-DC charger for alternator charging and a SmartSolar MPPT controller for solar input.

How do I check battery status?

The Alpha batteries offer Bluetooth monitoring. The pre-wired boxes also include a SmartShunt for detailed state-of-charge data.

Are these kits suitable for marine use?

The IP67-rated Alpha batteries resist dust and water ingress, which makes them a practical option for boats and other exposed installations.
