    Off-grid lifestyles, including vanlife, solar-powered workshops, and mobile installations, require energy storage solutions that are reliable, safe, and long-lasting. This study evaluates the Hoolike 25.6V 100Ah LiFePO₄ battery in real-world usage through a collaboration with the YouTube channel La Virée d’Hector. The analysis focuses on technical performance, safety, and practical application in mobile environments.

1. Introduction

    The growing adoption of mobile living and off-grid energy solutions has increased the need for advanced battery technologies. Lithium iron phosphate (LiFePO₄) batteries are recognized for their safety, high energy density, and longevity. Through collaboration with La Virée d’Hector, we conducted a comprehensive evaluation of the Hoolike 25.6V 100Ah battery in a classic camper van setup, providing insights for enthusiasts and professionals alike.

2. Materials and Methods

2.1 Battery Specifications

  • Type: LiFePO₄

  • Nominal Voltage: 25.6 V

  • Capacity: 100 Ah (~2560 Wh, 2300 Wh usable)

  • Dimensions: 50.2 × 18.7 × 24.1 cm

  • Weight: 21 kg

  • Protection Rating: IP67 (dust-tight, temporary immersion in water)

  • Battery Management System (BMS): 100A, regulates overcharge, over-discharge, and temperature limits

2.2 Testing Procedure

The battery was evaluated using the following methods:

  1. Initial voltage check to ensure balanced cells and readiness for use.

  2. Comparison with 12V series setup to analyze voltage balance and installation efficiency.

  3. Installation in a camper van to verify compatibility, weight distribution, and physical fit.

  4. Performance tests during typical off-grid operation, including powering appliances and monitoring voltage stability.

  5. Multi-source charging assessment: dedicated charger, solar panels via MPPT controller, vehicle alternator with DC-DC charger, and generator.


3. Results

3.1 Installation and Space Efficiency

  • Compact dimensions and 21 kg weight allow flexible installation in side compartments, under seats, or storage areas.

  • Integrated BMS ensures automatic cell balancing, simplifying connection with inverters and reducing system complexity.

3.2 Safety Features

  • IP67 rating guarantees dust-proof and temporary water immersion protection.

  • LiFePO₄ chemistry reduces risks of thermal runaway, short-circuits, or explosions.

  • Terminal placement and optional fuse/circuit protection prevent accidental electrical contact.

3.3 Energy Performance

  • Usable energy: 2300 Wh

  • Maximum continuous current: 100A

  • Temperature range:

    • Charging: 0°C to 45°C

    • Discharging: -20°C to 60°C

  • Supports fast charging (<5 hours with compatible charger)

  • Supports series and parallel configurations for expanded capacity (up to 20.48 kWh total)

3.4 Comparison with 12V Series Batteries

Feature 12V Series Setup Hoolike 25.6V 100Ah
Voltage uniformity Poor Excellent
Cell balancing None Automatic via BMS
Installation complexity Medium Simple
Risk of premature aging High Low
Overall stability Variable Consistent

4. Discussion

    The collaboration with La Virée d’Hector demonstrates the practical advantages of a 24V LiFePO₄ monoblock system in off-grid applications. The simplified installation, integrated safety features, and high energy efficiency make this battery ideal for mobile and solar-powered setups. Compared to 12V series arrangements, the 25.6V 100Ah unit reduces losses, balances cells automatically, and provides stable power for high-consumption appliances.

5. Conclusion

    The Hoolike 25.6V 100Ah LiFePO₄ battery is a reliable solution for off-grid energy systems. Its advantages include:

  1. Safe and stable power delivery for mobile and stationary setups

  2. High capacity and energy efficiency suitable for demanding applications
