Latest company case about  12V LiFePO₄ Battery Powers Off‑Grid RV Adventure

Client: Recreational Vehicle (RV) Owner – Alberta, Canada
Application: Off-grid camping power supply
Product Used: 12V 200Ah LiFePO₄ Battery Pack
System Specs: 2.56 kWh usable capacity, paired with 200W solar panel & 1.5 kW inverter

Background

The client is a full-time van-life traveler exploring Canada’s remote areas with no access to grid power. They required a lightweight, safe, and long-lasting power source for daily essentials, including:

  • LED lighting

  • Laptop and phone charging

  • 12V fridge and water pump

  • Occasional use of a small induction cooker

After using AGM lead-acid batteries for years, they wanted a solution that offered:

  • Longer cycle life

  • Faster charging

  • No maintenance

  • More usable capacity (deep discharge)

Our Solution

We supplied a 12V 200Ah LiFePO₄ Battery Pack, which replaced two bulky AGM batteries and offered:

  • 2.56 kWh usable energy

  • >6000 cycles @ 80% DOD

  • Built-in Battery Management System (BMS) with low-temp cut-off and overcharge protection

  • Compatible with standard 12V inverters and solar charge controllers

  • Compact size and only ~24kg, making it easy to install under a seat

Performance & Results

  • ✅ Runs 12V appliances for 2–3 days without solar input

  • ✅ Charges in 4–6 hours via solar on sunny days

  • ✅ Saved ~40% weight vs previous lead-acid setup

  • ✅ Reduced charging time by 50%

  • ✅ No maintenance or acid leaks during travel

  • ✅ Estimated 10+ years of reliable power

Client Feedback

"This battery totally changed how we camp. It’s light, lasts forever, and I don’t worry about checking water levels or losing power at night. Even in sub-zero temperatures it worked flawlessly with the built-in protection."
