The Hobbyking Cellmaster 7 has been designed specifically for checking the overall and individual cell voltage of Lipo batteries. It will give you an instant reading of the remaining capacity of the battery taking the guess work out of it.
The Hobbyking Cellmaster 7 also allows you to test and centre your servos. Simply attach your servo and select the servo tester mode (BEC required).
The Hobbyking Cellmaster 7 is a must have battery checker and servo tester for the toolbox of every RC pilot/driver!

The battery checker do his job pretty good... i have see the same device whit different brand name for much more money ! great deal HobbyKing !!Simple and easy to operate. The servo test doesn't know how to do it.Simple and easy to operate. The servo test doesn't know how to do it.Perfect gadget to check batteries before and after flight, works with LiPo and LiFe. Great also for checking servos.
Fast shipping, 5 working days to Romania.best thing ive bought for my lipos and great for testing servos aswell.
checks the percentage of batterry left and i was suprised as to how much life was left after 8 mi flight timeWorks well. I like the cell max/min voltage and difference reading. Only downside is the need to have a seperate 5v supply to use the servo tester function as well as a LIPO on the balance connector which powers the unit.I am not sure what meter is accurate / inaccurate but I bought this and the Cellmeter 6 form the AUS HK store and they give very different readings. I wanted to calibrate my lipo charger and bought the two of them to satisfy myself of their accuracy. Now that they are totally different I wont be touching my charger and modifying anything.
My iCharger cell readings closely match my cheapo digital multimeter which are close to the TP lipo charger I have. I expected these two meters (Cellmeter 7 and Cellmeter 6) to be similar.
To give an example on the same 3S battery.
Cellmeter 6: 3.842V 3.843V 3.848V
Cellmeter 7: 3.827V 3.824V 3.841V
My charger needs to be calibrated to .001V which is why I bought these meters. Back to square one now.I have never seen these beore. A critical must have tool to keep sn eye on my lipodwas slightly disappointed with the plastic outer case but the product still works well and does the desired job :) cheap product, great valueGreat tool to ride along your batteries.
