Camper Trailer Power Solutions

Camper Trailer Power Solutions

Save serious weight (40–80kg), get faster charging, and get greater usable battery capacity for your camper trailer with lithium battery solutions from Revolution Power.

Off-Grid Essentials — 100–200Ah Lithium Systems

Looking to save weight and upgrade your camper trailer to lithium? Our 100Ah and 200Ah 12V lithium batteries are the most popular choice for hard-floor and soft-floor camper trailers.

The weight saving alone is a game-changer — a 100Ah lithium battery weighs approximately 12–14kg versus 28–32kg for an equivalent AGM. On a camper trailer where every kilogram affects tow vehicle handling and fuel economy, that matters.

Typical Camper Trailer Setup

• 12V 100Ah Revolution Power lithium
• Victron Orion-Tr Smart 12/12-30A DC-DC charger (charges from tow vehicle while driving)
• 200W folding or fixed solar panel + Victron SmartSolar MPPT 75/15
• Victron BMV-712 battery monitor
• Victron Blue Smart IP65 charger for shore power

This setup comfortably runs a 40L compressor fridge, LED lighting, device charging, and a water pump for a week without solar input — and indefinitely with good solar conditions.

Hard-Floor & Off-Road Trailers

Larger off-road campers with full kitchens, showers, and hot water systems benefit from a higher-capacity system:

• 200Ah+ battery bank
• 400W solar
• Victron MultiPlus-II for 240V appliance capability
• Full Victron monitoring via Cerbo GX

Why Not Just Use AGM?

AGM batteries are heavy, deliver only 50% of their rated capacity before damage, and take significantly longer to recharge. On a camper trailer where weight and charge speed are critical, lithium simply outperforms on every metric that matters for touring.

Frequently Asked Questions

What's the best battery setup for a compact camper trailer?

For most hard-floor and soft-floor camper trailers: a single Revolution Power 12V 100Ah LiFePO4 with a 200W folding or fixed solar panel and a 20–30A MPPT controller. This runs a 45L fridge, LED lighting, phone charging, and a fan comfortably for 2–3 people.

Can I charge the camper battery while towing?

Yes — using a Victron Orion-Tr Smart DC-DC charger. Connect it between the tow vehicle's battery and the camper's lithium battery via the trailer plug. It charges at up to 30A while driving and automatically disconnects when the ignition is off.

How do I stop the tow vehicle battery from discharging into the camper overnight?

The Victron Orion-Tr Smart DC-DC charger handles this automatically. It detects engine start/stop and only passes current when the alternator is running. When you switch off the vehicle, charging stops.

Is 100Ah enough for a long weekend?

For a 3-night trip with a 45L fridge, lights, and device charging: 100Ah is usually sufficient with 200W solar. In heavy overcast, you'll use 50–60Ah overnight and the solar replaces that during the day.

What's the difference between the Low Draw and High Draw battery variants?

Low Draw (50A continuous) suits fridges, lights, pumps, and standard camper loads. High Draw (200A continuous) is needed for electric winches, high-power inverters, or trolling motors. Most camper trailer setups are fine with Low Draw.
