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.
Review: Love the dynamically updating highly informative LCD screen - Plug in the 12v power supply to the back. Prepare your phone for the QR code to download the app if you want to monitor the settings remotely (you can operate the buttons from the app). I had to pair with specifically one of the two new bluetooth broadcasts. I believe one is for android, the other for iphone. The app will show some insane 600v measurement graph-- you can zoom in with finger gestures to get down to the typical 12V range. To test battery capacity: Screw down the fork leads to the front left green connector block. The black fork is closer to you- red closer to fan. Make sure you open the connector block first with flathead screwdriver otherwise you'll likely screw down the forks in reverse by a counterclockwise motion and the forks (or USB board) will dip up at an angle. Attach leads to battery (or cell). Set the cutoff voltage to your particular battery (or cell). You need to know this!!! For a 12V Lifepo4 battery capacity test above 15aH battery: make sure it is fully charged. set cutoff to 10.5V. clear data (this just clears the test metrics and gives clean slate). You'll want to use CC to test capacity. Set CC to max allowable: you will probably start at 13A and work up to the 14A range (if you're in no rush, set it lower). Keep note of the MOS temp range and don't exceed 99C. Don't even up that in the settings. You can get 14.3A+ if you prop up the tester and have a fan blowing under the heatsink and the mainboard. Try not to exceed 180W. This advice is for 75F ambient. Be more conservative with the amp settings if ambient is hotter, you'll burn up the MOSFET under the heatsink. If you trip the temp alarm too much it will stop the test. You can resume, but you need to lower the amp draw first or fix your cooling. Don't push it! You can test a 314Ah 12V battery in under 24hr with the above method.

### ⭐⭐⭐⭐ Good Li Ion capacity tester
*by J***. on December 10, 2024*

I bought the 180 watt version of this capacity tester. It is good for testing tool batteries, which is my main use. The instructions are OK - but they are very small and hard to read. However you can find full screen instructions online and lots of youtube videos for the ATORCH DL24 which helped me. Apparently there is a free Windows app for these capacity testers, although it is not mentioned in the product description on Amazon. The Windows app is basic and not much to brag about however. So far I have used it to test 5-S Li Ion tool batteries, and it is working great.
