Abstract

    When it comes to power solutions, durability is just as important as capacity.
In this remarkable field test, Hungarian creator MikRobi takes the Hoolike 25.6V 100Ah LiFePO₄ battery through extreme trials — from powering high-wattage appliances to full water immersion.

1: First Impressions & Setup (0:00–2:41)

    The video opens dramatically — the Hoolike battery undergoes a water splash scene within seconds. Then, MikRobi gives a short introduction to the brand and specifications:

• Model: 25.6V 100Ah LiFePO₄

• Key features: Smart BMS, Bluetooth function, waterproof casing

    By 2:20, the setup includes a wattmeter and shunt, providing precise real-time measurement of current flow, voltage, and energy use — a professional approach to validate real data.

2: Documentation & Build Quality (2:42–3:14)

    Next, MikRobi shows the outer casing and user manual — both emphasize safe installation, BMS management, and waterproof structure.
    The casing appears solid, with reinforced sealing edges and industrial-grade connectors, hinting at a strong resistance to external moisture or vibration.

3: Real Power Tests — From Fans to Grinders (3:15–8:24)

    Practical testing starts with fans, wattmeters, and current displays, showing smooth operation with stable current and low ripple.
    Then, the experiment escalates — a grinder test pushes the power draw significantly higher. Despite the surge load, the voltage remains consistent, proving excellent discharge stability.

    Although a minor irregularity occurs (as noted by the reviewer), the system continues functioning — demonstrating that the BMS protection reacts efficiently to anomalies, ensuring both safety and longevity.

4: Heavy-Duty Test — 3kW Load Challenge (8:25–13:57)

    This segment is the real highlight.
MikRobi connects a radiator and heater, testing whether the Hoolike 25.6V battery can handle up to 3,000 watts of power.

The outcome is impressive:
✅ The system delivers strong and consistent output.
✅ Temperature remains controlled under continuous load.
✅ Voltage drop is minimal, confirming high current endurance.

    The reviewer then connects a washing machine and heat radiator simultaneously, monitoring internal temperature changes. Even after minutes of operation, the battery maintains safe temperature limits, showing that Hoolike’s thermal management and BMS synchronization are functioning perfectly.

5: Durability in Action — Grinder and Metal Tests (13:58–15:47)

    To further test real-world performance, MikRobi uses an angle grinder to cut screws, simulating mechanical vibrations and high transient current draw.
The battery performs flawlessly, providing steady power without triggering protection shutdowns — an excellent indicator of robust current delivery and surge resistance.

6: The Waterproof Test (15:48–21:14)

    Now for the most dramatic phase — the full waterproof test.
    The battery is sprayed and submerged, then carefully inspected for signs of water ingress. After immersion, MikRobi opens the casing — the interior remains almost completely dry, proving the design’s integrity.

    He measures the post-test voltage with a multimeter — still stable and within normal range.
    One small internal component shows slight exposure to moisture, but the core battery and BMS remain undamaged.
Result: Waterproofing success under real conditions.

🧠 Step 7: Technical Analysis & Takeaways (21:14–22:48)

In conclusion, MikRobi summarizes the results with practical insights:

• No significant internal water damage despite direct exposure.

• BMS operated effectively under multiple load types.

• Safe, consistent voltage delivery even during high-load or wet conditions.

• Mechanical and electrical integrity maintained.

    This experiment proves that Hoolike’s LiFePO₄ batteries can withstand tough, real-world environments — combining power, safety, and resilience.

Key Technical Insights

    The focus of this test lies in structural protection and current endurance.
Unlike standard lithium batteries, the Hoolike 25.6V 100Ah LiFePO₄ integrates:

🔸 Sealed casing with IP67-rated waterproofing
🔸 High-efficiency BMS for balanced discharge and temperature control
🔸 Stable internal resistance, ensuring performance even under load surges

These features make it ideal for:

• Outdoor energy systems

• Marine or RV applications

• Workshops and backup power setups

Conclusion — Strength Beyond Specs

    Through extreme testing — from grinders to water immersion — this review shows that Hoolike batteries are built for resilience.
    They are not just about energy; they represent trustworthy, real-world endurance.

    For those seeking a reliable LiFePO₄ power source that can survive both storms and heavy workdays, Hoolike delivers.
