Hi, I'm changing my Lipos from 3s2p to 4s2p and I'm wondering if the BEC on my Kontronic Beat 40-6-12 will still work or shall I put my UBEC on instead. If a higher voltage setup is used say 5s or 6s is a UBEC needed with the CC ESCs as well?

If you use 5s or 6s you cannot use BEC from the ESC. I think that 4s just passes the limit for BEC on the ESC. They generally dont recommend using the ESCs BEC over 10 round cells.

I would say to go with the UBEC

Hi there

I have just had a look on the kontronik web sit and i see that the 40-6-12 esc only supports 12 cell if thart is so then the voltage is 14.4 volts on nicads and ni-mh the 4s2p li-po would be 16.8 volts fully charged
unless i am reading the infomation wrong i would be carefull and find out all the infomation first otherwise you may end up buying a new ESC

I say you have to get the Ubec if you have anything over 3s.

Yes steph, I was a bit worried about that but when I looked at the ESC box that it came in it says it is good for 6v to 16v but now I'm not so sure.

The Smile 40-6-12 is your partner for all main-stream airplane applications with brushless motors. No matter if 2, 4 or 6 pole types - Smile 40-6-12 is good for all of them.

6-12 batteries, 6 to 16V
40A continuous, 50A short duration
17gr without cable, 31gr with cable
2,5mm² cable
49x28x7mm
2A BEC
BEC short circuit protected

With this infomation i would not use the 4s li-po as the voltage would exceede the limit of the esc
