Hi Hector,<div></div><div>Personally, I have used the MPI Regulator Switch MK2 (I think) for a while now and never had any issues with them.</div><div>I've used the 2 cell LiPo Batteries as well as 2 cell LiOn batteries and they work great.</div><div>If anything goes wrong with the switch they default to ON. From the factory they are set at 5.5v (I may be out by a little here but I think it is close to this) and can be changed if needed.</div><div></div><div>Just my 2 cents worth (Or maybe 1 cent in this economy)</div><div></div><div>George</div>
