I think this is the one i was thinking of before, not sure if it's appropriate for the batteries we use. Can anyone with a better understanding verify if this would be a good option?

Yes Steven, the Accumate 5 is indeed a good charger!

Al, both my teams use the TecMate Accumate 5 and they work great. If you have 5 batteries on the go you will always have a couple ready for your next match. Both my teams run heavy draws on their batteries running 6 motor drivetrains and the Accumate keeps up just fine. With this charger you can also combine multiple charging ports to increase the charge rate ie: 1.8A from 3 bays = 5.4A if you need to get a battery charged FAST. They are a great charger and you can safely leave the batteries plugged in and charging as the unit is fully automatic and includes a long-term maintenance feature. It also has integrated diagnostics and has served invaluable in notifying us of defective batteries before they cost us a match. We picked up ours at a dealer cost of $239. The cybergnomes' title sponsor, JT's Snowmobile uses them for all their batteries and let us try it out for our competition in 2010. Since then we have never looked back.
