VS- 3S and VS- 3P are t echnical ident ical but in different
pack ages. VS- 3S has a plast ic case and a carbon fiber
front panel. Size and m ount ings are sim ilar t o st andar d
serv os w hich m ak es it easy t o put it int o serv o m ount s.
VS- 3P com es in a heat shrink ing t ube and can be m ount ed
w it h double sided adhesiv e servo t ape. VS- 3R ist t he sam e

Fun ct io na l Pr inciple :
Many receiv ers, serv os and ot her elect ronic dev ices are
designed t o be pow ered w it h 4- cell NiCd bat t ery pack s.
Therefore t he m ax im um allow ed v olt age is 6 v olt s. The
usage of a 2- cell LiPoly bat t ery pack is not allow ed since it
has 7,4 Volt nom inal. This requires a v olt age conv ert er
w hich reduces t he LiPoly volt age t o t he low er
receiv er/ serv o volt age.
VS- 3S/ P/ R has a built - in v olt age regulat or w hich w ork s
w it h 2 or 3 LiPoly cells or 5 t o 7 MiCd/ NiMH cells. The
reduced out put v olt age can be adj ust ed bet w een 5 and 6
v olt s by t he user.

Con ne ct ion:
VS- 3S/ P/ R has silicon cables for t h e bat t ery connect ion.
RED is t he posit iv e pole, BLACK is t he negat iv e pole.

This LiPoly Cont roller has an ex t rem ely low - loss v olt age
regulat or. Even w hen t he bat t ery is alm ost em pt y it can
produce a st able out put v olt age. The qualit y of t he out put
v olt age depends m ainly on t he bat t ery qualit y and t he

Use short cables bet w een bat t ery and VS- 3x and use
only good gold- plat ed plu gs.
Use only high current bat t eries lik e m odern LiPoly
cells and put as m any LiPoly cells in parallel as
required t o get sufficiant cur rent for y ou r m odel.

uC- Ba t t e r y M onit or
Monit oring t he v olt age of LiPoly cells is absolut ely
necessary . These cells can easily be dam aged if
