Regulating voltage, temps, charge time, safe voltages not to upset the lipo.. Had one of those weekends so I moan lol.. upside is I hit 50 mph on quite short road.
its all preset...charger looks after voltage levels..ESC stops Lipos overdischarging...temps ? if you gear it properly you dont need to worry..same as nitro on that score...I run 3 BL RCs and cant remember when I last had to faff about...
