Sentry 25A 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 guard.

How long are the battery, receiver and balance wires on this ESC? Do they ship long and allow you to shorten them, or will I possibly need extra wire to lengthen them?

I cannot get the throttle to arm on 4 different Turnigy ESCs, two of the brand new SENTRY 25As. Any tips on getting these blooming things to work properly? I'm getting really frustrated.

They do not beep as expected when you plug in the ESC. I'm following the instructions exactly as described, tranmitter wise, etc.

With transmitter on, throttle 100 percent, I plug in the ESC, I get 3 beeps, which I assume is the number of cells in my LIPO, then about 5 seconds later I get a long beep.

Hints, tips?

TIA

Maybe your throttle channel is reversed? Btw, do not plug in esc with 100% throttle, throttle up after you plug in.

Beaufighter,

Thanks for the tip. I finally got a couple of them working. I used a different tip I found somewhere.

I unplugged the ESC from the receiver. Then I powered up the transmitter. Then I powered up the ESC. Then I plugged in the ESC to the receiver. This somehow made the ESC "reset" itself and it started to work properly.

Cannot recommend this methodology, but it seemed to work for me.

Is the Sentry 30A available?
   -boot (72%)
No, unfortunately. These sentry ESCs are great, they're the only ones I use now. Contact HK and ask them for one in 30A. I have, and if enough demand is heard They might produce them. Thanks
