9920 14 cells, no UBEC?
 

What would happen if you were to run 9920 with 14 cells and no UBEC?

chances are you would be ok but i wouldnt recommend it. you would probably fry the internal bec or who know, maybe the whole controller. im not really sure, although i have heard of people running up to 18 cells with no bec and no ill effects.

I ran my truck last night with 14 cells and no UBEC, just for about 5 minutes, could not wait, it ran AWESOME and then .......... all of a sudden it just stopped, i picked it up, unplugged one of the batteries and plugged it back in and it was fine, i think it happened because my antanae is a little scuffed up, i will get a new reciever and try it out again.

Accually it was the internal bec that was your problem. It is telling you it was to much.

Whats that.... i hear a voice.... its your controller hissing.....UBEC, NEED UBEC! lol

just get a UBEC before you fry the internal BEC

NOOOOOOOOOOOOOOOOOO!!!!!!!!!!!!!!!!!! HIssing bad, very bad!!!!!!!! LOL

I will be ordering a UBEC very soon.

Damn right your getting one;)

I tried to run mine before hand cates. It would go and kick off until unplug and plug the batts back in. I think i tried 14 at first to. It was my first brushless system.

Did you Let the smoke out? AKA does it still work, or did that fry it?

It let the smoke out later on. It seems to run better on a ubec though. It kept cutting out faster and faster the more i ran it. I don't know if i did damage or not.

Another option, while you're waiting for a UBEC, is to disable the internal BEC on the controller and use a receiver pack. It's not as light or as convenient as a UBEC, but it does the job.
