i use a one of these
http://www2.ripmax.net/item.asp?item...tegory=090-020
it charges my cars hump pack, my TX battry and a few spares, at the same time and when there fully charge it just trickles untill i unplug them.
it dosnt do glow starters, but i brought 2 glow starters and i charge one while i use the other, or if im going out fully charge em both (if u keep to the hobbie u end up with quite a few glowstarters

)
