That one lost the capacity when turned off and back on. This one remembers settings, capacities, also has several modes to discharge batteries. The early version had 2 dials and you had to adjust it often to pull 150 ish watts. This one has a constant power setting. Set it at 145 or so and it will pull that no matter what the voltage as the batteries drop. Wiring on the purple board units is a little strange. Look at the diagrams. All 4 terminals have to be attached. I do like the full color hi-res display. The 4 resistor purple board "said" color display. But it is definitely monochrome. It was returned if you can't tell. The full color unit actually had some instructions, which were a little criptic... But it was relatively easy to figure out. I do like the on off switch they added as well... Review: Does the job - I started making my own battery packs & rebuilding them too. This works well and connects to my phone for display… was a bit of learning to use it, but now I’m very happy with it! Great for smaller batteries! Will do bigger batteries just would take a while for results. ## Features - 2.4" Large Screen Battery Load Tester: Featuring a high-definition color screen, this electronic load tester provides clear and precise readings.

This works well and connects to my phone for display… was a bit of learning to use it, but now I’m very happy with it! Great for smaller batteries! Will do bigger batteries just would take a while for results. ### ⭐⭐⭐⭐ Nice unit but no power supply is included. *by U***N on June 23, 2025* Value for money: The unit requires power and no power supply is included so you can't use it "out of the box". You have to supply a 12V @1 amp power supply or provide a USB C power brick. A USB cable is included but no power brick. It's a very capable unit that measures everything you can think of. Fine print on the display is hard to read under some light conditions. I ran it at 12V @ 10 amps for an extended time with no issues. I wouldn't use it with power sources over about 50 volts do to the shock hazard from exposed traces. Overall I like it and would recommend it. ## Frequently Bought Together - MakerHawk Battery Load Tester - 150W 200V 25A USB Load Tester 4-Wire System Adjustable Constant Current Voltage Discharge Lithium Battery Capacity Tester Electronic Load Tester - FNIRSI USB Tester 4-28V 7A LCD USB A&C Voltage Current Power Tester Multimeter with App Software, Fast Charge Detection Trigger Capacity Ripple Measurement, PD2.0/PD3.0,QC2.0/QC3.0 - Treedix USB Cable Tester Board USB Cable Checker Data Wire with Acrylic Case Charging Test Data Line Type-C Micro Type A Type B --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/673563325-makerhawk-battery-load-tester-150w-200v-25a-usb-load-tester](https://www.desertcart.co.uk/products/673563325-makerhawk-battery-load-tester-150w-200v-25a-usb-load-tester) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-29*
