TOMTOPTOMTOP Smart Digital Battery Capacity Checker for LiPo LiFe Li-ion NiMH NiCd Battery

Just what I needed. A very good product that has been very reliable. Great for double checking batteries before you go out to fly quadcopter.

a simple reliable tester for the most common sizes of LIPOs. It could have a little more solid feel to the casing though. I'm pretty sure if i dropped it on concrete or tile it would break. For something you carry around and use frequently in different places as a hobbyist might use this, some extra durability would be good.

Connected a NiMH cell to it, nothing happened. No display, nothing. Connected a LiIon cell to it, same thing. Dead on arrival. Sent it back right away. Wasted my time testing it and sending it to the UPS drop off location. The only thing good was the Amazon return process.

it is doing the job perfectly, especially the internal resistance IR specification is just a life saver. definitely every hobby enthusiast should have it in its tool box!

The meter works as far as energy left in battery. No other functions work! Will not tell voltage of each cell and nicad plug does not work either! Get a better meter! I have three, different brand, and all work as they should!

Not useful

works good but very complicated to use

Excellent for checking the condition and staying on top of your Lipo batteries. I use it for checking internal resistance, cell voltage and battery voltage. Very lightweight easy to use at a great price.
