Q

Is it possible to adapt this unit to test Li-ion camera batteries that have no balance plug, just contacts to fit into camera?

A
  • No, only when the battery connector and electrical connector is the same as the test that was able to connect using the forehead.

Q

no instructions , no wires with this battery meter . what do i need to make this work ?

A
  • I found some instructions online. You use the balance plug of the battery, if it is a LiPo and plug it in the the far right of the pins, when you are holding the device with the screen facing you. Make sure the ground wire of the balance plug is lined up with the indicator on the right side of the device, or it will no… see more I found some instructions online. You use the balance plug of the battery, if it is a LiPo and plug it in the the far right of the pins, when you are holding the device with the screen facing you. Make sure the ground wire of the balance plug is lined up with the indicator on the right side of the device, or it will not power on. The menu structure is a bit complex, so I highly recommend searching out the pdf instructions. Here is the link I found a copy at: https://dymondusa.com/instructions/20179.pdf see less

Q

Will the real capacity of the battery be displayed after full discharge?

A
  • Not to sure what you mean by a full discharge (100%)? The checker shows voltage on individual cells and percent. Plus it shows total voltage of all cells and charge percent of battery. Works great for me!

Holding down the Cell key more than three seconds opens the secondary menu. There you can set the balance gap and balance packs, set the discharge level and discharge packs and select the IR function and generate a IR number for each cell by cycling through the cells using the mode key. I compared the IR results with the ones returned by one of my chargers and they were similar. Just remember the first number that pops up is for only one cell. I haven't tried the ESC/Servo tester function yet. It looks like you can plug your ESC or a servo into the small port and the battery balance tap into large port and get a series of pulses that will rotate the servo. this is a very nice all-in-one battery checker/balancer. see less

    I was told at my local hobby shop that I needed a battery checker since I had several different types of LiPo batteries as well as some older NiCads laying around. I didn't want to break the bank buying one. Saw this on Amazon and ordered it. I'm new to the hobby scene that is using LiPo batteries, so when I received this unit thought that I should come with a cable to plug into that set of male pins on the end. Went to local hobby shop and the told me that the unit looked just like thier more expensive unit and appeared to be same quality. Then they showed me how the variouis LiPo batteries hook up right to the tester using the battery's balance connector. Duhhhh, boy did I feel stupid. My bad as my son would say. Works great, now that I know how to use it. So other than maybe a bit more descriptive set of directions for newbies, this is a fantastic buy if you are in the market for a battery tester in your RC bag of tools.

    The nicest feature about this unit is the percentage display. It is the reason I bought it. Whether you are checking a 2, 3, 4, or more cell LiPo battery you can compare the same number. This is easier than remembering what voltage you should have for each cell count. You could look at individual cell voltage but the percentage gives you a picture of the entire pack. I check voltage every time my plane is on the ground. I never take off under 80%. It quickly gives you a feel for how much of the battery you are using per flight time. cons - the pins that the balance plug go into feel weak, I'm worried they will break soon, but so far no problems.
