[savagebeast26]

hey guys well im jhautz's friend and i am thinking that im gona some how make the fma cellpro 10s charger get extra special ordered at my local hobbytown and it says it doesnt come with a power suppy but that you can ajust the input power ampage and i was just wonderinf if you think that a 5 amp power supply would be able to keep TWO 4 cell 5000mah zippy lipo batteries charged through out the entire raceday without it dying or losing alot of power by the end of the race help would be greatly appreciated Thanks DirtDawg offroad RC member
