This highly accurate piece of test equipment is a 'MUST' have device, if you are questioning those claims of sellers of lithium batteries. With this device, you can top-up charge questionable batteries to find their true capacity, after draining them down to their safe limit. Then, you can verify those readings by then, charging same batteries up again under test, in a repeat cycle mode up to their top (safe) voltage to determine and compare actual capacity of said batteries. I have several units running in tandem to allow me to check many batteries at-the-same time under same time test. The beauty of all this is that you can run several of these units at-the-same time using 'one' PC, by clicking in "add device", in the software tool bar. I wish I would have had this, when I purchased all those 'Fake' lithium batteries, that I thought was a good deal at-that-time. We live and learn. But, now I can learn before living the mistake. You will see what I mean, when you purchase a couple of these units.

In spite of the fact that 'Covid-19' delayed my order and delivery by 19 days, I am more than happy to have another one of these units arrive finally on my door-steps. (It was worth the wait.) Now, with this highly accurate and precise piece of test-equipment, I can run my other (3) units previously purchased simultaneously together with this one arriving, using the software to check all of my 18650 batteries along with lead-acid batteries quicker. These babies check battery amp capacities as well as charge said batteries, at a rate that you decide by inputting said figures. You can also 'Cycle' test batteries. One can view, via said software in real-time, curve displays on your computer monitor. When you down load the software, from the 'ZKE' web site, you now have the option to add-a-new device (multiple times) to monitor on your computer(lap Top). No more will I have to take the word of a seller trying to sell me batteries that are over-rated and under-performing. My only regret, is that I did not buy all 4 of these units at-the-same time along time ago. By the way, I forgot to mention that I have 2 of each models. The one difference is the fact that the 2 units on top of the desk-top versions can handle up to 20 amps of discharge, whereas the bottom 2 units can handle up to 10 amps of discharge. Both can deliver a charge of up to 5 amps of charge to batteries being tested. The bottom 2 units can handle more battery chemistries than the top two units. By the way, the photo snap-shot of the graph looks poor in site, due to my laptop screen not agreeing with my cheap camera phone. It is time to buy a better camera phone. The ZKE company knows how to make reliable test equipment at a very good price.

Now, I have purchased 3 of these EBC-A20 units. Having 3 of these units allows me to cycle test (discharge/charge...) 3 Lithium battery packs at-the-same time, as well as, by using the software provided from the manufacturer, I can set parameters as well as graph results for printer. The software allows me to monitor all 3 units at-the-same time so, saving me time in running multiple cycle tests. The software is user friendly and easy to figure out. Now, I can truly tell the exact capacity of my Lithium battery packs. Also, by having the computer running the cycle test (as many as you want) in real-time, I can see any irregularities during the cycle test. In short, buying more of these units saves me precious time performing 3 separate cycle tests at-the-same time. The big advantage is having these printed out charts/graphs, that you can label for future use in knowing the health of your battery packs.

BR-9C 2-in-1-Handheld-Portable-Digitalanzeige Elektromagnetische Strahlen- und Kernstrahlungsdetektor Geigerzähler Vollfunktionsfähig
US$149.99 US$199.99

Q: With the Geiger detection tube contained within the case and not a separate detector (hand held tube) like the originally designed, will this unit be able to detect ore samples dug up during mining for same? In short, how close must an ore sample be to the case at time of mining? Also, if I place a smoke detector (which contains a small amount of radioactive material) near this unit, how close must it be to detect, if in fact it is able to detect?

gefragt von George auf 2021-11-15 03:26:44

The seller How close the distance can be measured depends on the radiation intensity of the radioactive material. There is no absolute standard distance. Example: For example, a patient who takes iodine 131 can detect it 30 meters away

Q: What is the distance measurement between the battery holding terminal plates? In short, will this unit function with a standard 12 volt A23G battery found in remote control units? I need the measurements to know for certain.

gefragt von George auf 2020-02-29 02:30:24

mikey553 It is 35 mm, but up to 38 mm will fit. It will work with 12 V, but closer to 15 V is better.

Q: Please send me via e-mail attachment of the user manual of the unit I purchased from you. (EBC-A20 Battery Tester) I tried printing a copy from the manufacturing company ZKETECH over-seas but, found it not printable by printer, as it states on site. Also, do I need to load software other than what I have already downloaded for my other 2 units EBD-A20H and EBC-A20H? Again, my e-mail is:*****. I can't wait to place it next to my other units so, I can check more batteries at-the-same time.

It was worth the money I paid for it. Super welder for the beginner without having to pay those outrageous prices. The only draw-back is the fact that you can only weld up to 3P stacks, as the 2 welding pins are too close to the front plate to do 4P. However, I plan to adapt a DIY spot welding machine automatic trigger handle for spot welding. IN SHORT, IT WAS A GOOD BUY!

Q: Can I get the schematics for this module, as I want to purchase at least 20 of these to teach my students, when it comes to knowing which resistors represent the upper limit along with the lower limit settings of voltage detecting. I guess that I could purchase one of the 1S, 3S and 4S versions to see which resistors are different. However, I would like to bulk purchase only the 1S units.
