Voltage booster

Hi :)

Im after a voltage booster to take 3s lipo (11.1v) upto 24v.

So far the only one ive seen is this;

but it looks quite heavy as its only for my beetleweight. Anyone know of anything lighter?

Its only to fire a tiny little solenoid valve so only has to provide an amp if that..

Thanks

Not the rating you were after but l've seen the solenoid so it may just do it if its only a quick switch on and off.
