Sentry 18A Brushless Speed Controller
The Sentry series of BESCs have an inbuilt battery cell protector.
By plugging the connector into the batterys charge port the BESC can ensure that the pack is balanced and that the pack never drops below a recomended level. This ensures your pack wont be over-discharged and destroy your battery. Its the best way to protect your expensive batteries. Considering in most cases your battery costs more than your BESC, its a wise investment to get a Sentry.
User Programmable, both via controller and optional programming card. The programming card is an excellent item as it instantly tells the user the current settings and with a few simple clicks of the buttons, the user can change the settings and have graphical reassurance of those changes.
The programming card is an excellent Item and simple to use!

Do you really need to connect the balancing cable when operating the esc.? If not, is it possible to cut the balancing port off if not needed.? I know the normal Plush esc would be the logical one to get, but they are out of stock for quite sometime now and I need an 18A esc very quick actually..
TIA and cheers, Jeff.

I am using the Turnigy 18A Sentry ESC and find that it does not result in balanced cells at the end of the flight. I am using a Hobby City cell monitor and find the cells to be 3.77, 3.53, and 3.81V. Should the cells be a lot closer? Thanks for your response.

They should be closer than that! I use the TowerPro 18-amp ESC's, and have never had an issue with the cells being unbalanced after a flight...you may want to try a different ESC.
