Review on DC Multifunction Battery Monitor Meter, LCD Display 0-200V & 0-100A, 🔋 Ideal for 12V/24V/48V RV/Car Battery - Digital Solar Power Meter, Multimeter Ammeter Voltmeter by Jasneet Jazzy

Was very excited to use them. I bought 4 different versions of it. The AC version has connectors that work surprisingly well. There is no way for the DC to make a good reliable connection. I spent several hours trying to get the included cables to stay in the clamps, but they just popped out with the slightest movement. After assembling them as best as I could, I tried to install the box as neatly as possible without disturbing the wires. About 2 minutes after switching on the system, the wire spontaneously jumped out again. This time it caused the battery to short out and the quite rare and expensive electronics to fail. How much would it cost to add clamps that are clamped and 100% trusted? The AC version has excellent connections. In the few minutes that everything worked I would say this is exactly the device I needed and it was very easy to read. Open up the case and solder right in if I ever decide it's worth the effort. Also note that the instructions are a very poor English translation with numerous typos and confusing word choices making them unusable. I definitely don't feel comfortable trusting them with my 96V DC batteries. If they are shorted due to defective crimp terminals. It's not just a bad day. I'm glad I was only working with the 12 volt system when they failed.
