Lipo Battery for Receiver?

Thanks John you have been most helpful!

the others helped too

btw u can consider a batt with a higher capacity but lower C discharge rating, should cost the abt the same and last longer;)

I'm not sure about BEC. but it seems that Regulator will give you a more constant voltage.

Also, if you use 3s on a regulator, you will have more energy wasted as heat and you can control less servos because you need to step down the voltage from say 11.4v to 5v. A good 5volt is wasted.

correct me if i am wrong, arent they the same thing with just different names? most external BECs are switching mode regulators.

agree with u that 3s is excessive, better to stick to 2s2p, higher cap, lower C rating to power the rx

Ya, I'm not sure.. So many names. confusing

I use 2s2p on my Nitro heli.

Hi,

Think the thread been discuss before, 3s got certain advantage in some way.

What about 2s1p? can use?? would the flight time be affected?

Guys wud like to ask a similar question but for electric plane. Recently i'm experiencing power cuts and symptoms are that of Receiver Battery Failsafe feature. Probably BEC not supplying enough to the RX and it goes into BFS mode.

Question is can I just plug a rx battery pack (nimh 4.8v) into free channel of the rx and would this eliminate BFS kicking in? I would still want my servos to be powered by the ESC's BEC.

Thanks
