I think that installing a MoSFET is one of THE most important and essential lipo ready upgrades, and I don't consider an AEG truly lipo ready until it has one.
Sorry trigger arcing really doesn't come into severe effect until higher voltage is applied, example : fully charged 11.1v lipo (12.6-12.8v) would cause severe arcing which in turn would create pitting on the trigger contact points and also on you're motors commutator/brushes. Arcing has almost nothing to do with load and everything to do with voltage. The main intent of a lipo battery is to be able to supply much higher load capabilities in a smaller package. Oh and as far as being "lipo ready" you do not need a mosfet for lower voltage Lipo's, hence why my standard non mosfet'd trigger contacts that see a 60c 7.4v 2200 Mah lipo will be in better shape than trigger contacts that see some 9.6v nimh(.....mah) battery . A 12v Nihm/nicd battery will do the same damage to trigger contacts as a 11.1v lipo battery would. Now in no way am I saying mosfets are not a good option , as they are (Just not always required). The archaic contact switch system that has been standard in AEG's for so long has many shortcomings, that can be improved by using a mosfet switch and delegating the trigger contacts to the duty of a relay, to improve electrical efficiency....Now only if we could get a brushless motor system in place for AEG's (non PTW platform) , we would be set.
