Our 6A charger from this year is not acting fully normal (releasing "strange smells", etc) but we have 4 competetion-legal batteries. With only one charger (the old 4A heat-sink charger), we have a minor problem. Is there any method by which one charger can simultaneously charge multiple batteries?

Team 30: We have High-Octane Lines

Last year, I bought a charger called a BatteryMINDer.

It is not a high speed charger (only 1 amp) but it specifically states that you can charge up to 4 batteries. Its other claim to fame is the fact that you never have to disconnect it. It actually maintains the health of the battery by preventing sulfination which is the formation of sulfer compound crystals when the battery gets too low, or over charged. The batterMINDer also claims to break up the crystals (which degrade battery performance), and even has a special button you can push to activate a special frequency to do that.

While not the right charger for quickly charging your batteries at a competition, it is great for in between events for your extra batteries. I kept last year's batteries plugged in all year. I attach the batteries together in pairs and then jumper the pairs together, and attach the charger. Our batteries seem to be in good shape.

I found this link for the BatterMINDer on google.com:
