I'd like to buy a few voltage regulators for using 7.4v 2 cell lipos as receiver packs in (relatively) high power electric boats and planes (upto 68 inch wingspan / 2000 watts)
Im thinking it'd be good to have a separate receiver battery for the planes instead of a BEC incase the motor/esc burns out and I lose all power/control (possible?)
Im hoping it'll also prevent the receiver's voltage from dropping too low and locking me out when i convert to spectrum 2.4ghz, am I right?

My question is, is there any disadvantage to getting a 5A instead of a 3A regulator (6v) if a low power setup were to only use say 1A max? (for example in a single servo 1/10th scale car)
Would the 5A drain the lipo faster or anything?

Or is the only difference the price? in which case it would be good to get all 5A?


Thanks everyone

I would not use less than a 5A regulator in a 68"/ 2000W airplane. I have two planes this size and use 5A regulators. Any bigger/more servos may require a higher current system.

Yea, thanks, definately plan to use the 5A with the larger models
What about the smaller models? Any disadvantage to using 5A instead of 3A?
