[AT] Battery Charger recommendations

[Steve W.]

In my case it depends on who actually makes the guts and how well they 
heat sink the chips. LEDs generate a LOT of heat right at the diode 
junction, pulling that heat away is a trick. If you stick with the 
better companies you generally will be OK. They generally use better 
heat sinks and components.
