## Overview

The Battery Capacity Tester 150W is a high-performance DC electronic load tester featuring four dynamic operating modes (constant current, voltage, power, and resistance). Equipped with a sharp 2.4-inch color screen and intelligent safety protections, it delivers reliable, real-time data monitoring. Its dual temperature measurement and smart cooling fan ensure durability and accuracy during demanding battery and charger tests, making it an essential tool for professionals seeking precise and safe power diagnostics.

## Description

Product Description Product parameter Test voltage: 2~200V Working current: 0.2~20A discharge power: voltage * current <150 W (The actual working current is limited by the maximum power, please adjust according to the law of energy saving) Built-in over-current, over-temperature, over-power safety protection function, if the protection interface pops up, please note that after the parameter adjustment, it should be adjusted to the maximum power before discharging , You can slowly adjust the preset value during start-up and discharge to adjust it to the maximum discharge power Four operating modes 1. Constant current operation (CC) 2. Constant resistance operation (CR) 3. Constant power operation (CP) 4. Constant voltage operation (CV) Three protection settings 1. Overload protection 2. Overcurrent protection 3. High temperature protection Product List 1. DL24 color display Bluetooth digital control curve version with Tesr x1 2.DC12V 1A power supply x1 3.USB data cable1 4. Temperature probe x1 5. Red and black single wire alligator clip wire x1

Review: I'd never used one of these devices before but I was working on a project that involves sending DC power over coax cabling and needed something to act as an adjustable load for my testing. This unit did exactly what I needed it to. The menus were fairly easy to figure out, and I liked that it gives you the flexibility to program a constant (or timed) voltage load, amperage load, or power (wattage) load. The screen is nice and bright and easy to read and the fan for dissipating heat during testing is reasonably quiet. I'm going to create a 3D printed enclosure for the circuit board since I'm not a fan of it being exposed but otherwise I have no reservations about recommending this model to anyone shopping around for a new DC load tester.
Review: I really like these load testers- very helpful in assessing batteries ACTUAL performance. There is an accessory that I’ve seen in use but cannot locate for sale that is a daughter board kind of arrangement that has common smaller battery sockets (AA, 18650, etc.) that would round this out perfectly. In any case, highly recommended.

## Features

- 4 operating modes: CC-constant current operation; CV-constant voltage operation; CW-constant power operation; CR-constant resistance operation. There are three intelligent safety protections in the discharge detection process, which can monitor the discharge tube status in real time, which is safe and reliable. An external wired NTC thermometer can realize dual temperature measurement inside and outside.
- 2.4-inch high-definition large color screen blue digital curve version of high-power electronic tube digital load meter. Intelligent temperature control color glare fan, high power, long life, durable cooling fan; 150W high power / 200V wide voltage / 20A high current, strong performance.
- Support testing Android, Type-C cable, Mini and other wires, and display a variety of test data on one screen. By checking and killing, by testing various data cable/charger test/discharge aging/DC power adapter current, voltage, power and other parameters, the operation is simple and the test is convenient and fast.
- 180W load discharge aging test, using intelligent temperature control light effect fan design, built-in large discharge tube, the temperature is maintained at about 50~80 degrees; easily test the voltage, current, capacity and other data of various power sources such as lithium batteries/USB chargers; Powerful, safe and reliable.
- If there is any abnormality in the product, whether it is return or exchange, you can contact us first, we will reply you within 6 hours, we will be happy to solve it for you, thank you.

It worked fine in my initial two battery tests. Then, it completely died. Screen won't come on, nothing.
