The update for that charger just adds more features. You might like to be able to "store" charge packs. When I'm done racing for the night, I like to store charge my packs so they are good to go for the next week/month I go out to race. This adds a discharge function to the charger. So say if you have a fully charged pack and you ask the charger to store charge, it will be discharging it to 60% capacity. And if you have a low pack, it will charge it to 60%.

I think it also adds a few other improvements and only takes about 5 minutes to do.
