I finally upgraded my battery tester after popping the MOSFET on the old one — and the new MakerHawk Electronic Load Tester is a serious step up. In this video, I walk through how to use this DC electronic load tester properly, avoid blowing it up, and explain why it’s a must-have tool for battery testing, solar setups, and USB power analysis.
🔧 What I cover in this video:
🔌 What broke on my old unit (and how to avoid it)
🔌 Hands-on with the new color fan and LCD interface
🔌 Constant current, voltage, resistance, and power testing modes
🔌 Live demo pulling 10A from a LiFePO4 battery
🔌 USB testing with Type-C, micro USB, and barrel jacks
🔌 Discharge data logging & power consumption monitoring
🔌 Temperature protection, cutoff voltage, and calibration options
🔌 Real-world solar charge + discharge testing in parallel
🔌 Bonus tips on Ohm’s Law, power limits, and safe wiring!
Whether you’re testing QRP batteries, USB packs, or full-size 300Ah monsters, this tool gets it done — for under $60.
