    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. 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.

    Just wish it had a manual. Works fine, but not intuitive how to connect your balance port to it. Hint: Negative goes against the top edge of the connector. Almost though mine was broken! Obviously, it's tolerant of being connected backwards.

    A good product for the price and easy to use. There's no reason not to have one of these if you have RC gear.

    I use this product for many lipo batteries and it seems to be very accurate as far as I can tell. AS far as durability, its electrical and plastic, so probably not all that durable. It is rugged enough for its intended purpose and a bit more. Honestly you can't beat the price either. Shipping was slow, about a month.

    The product works well but had a 3 cell battery that would only read 2 cells on. The battery was good so it left me wondering what was wrong with the unit. The unit worked fine on other batteries though. easy to check your batteries and designed well.

    Works as advertised and reads the cell charges nicely. Directions were not very clear on orientation of battery plug however. If it doesn't work, flip the plug upside down and should work fine.
