If you can't find it, why dont you start a new post there and ask for help.
What exactly do you need to know? Post some pics of your setup and I'll try to help. Like I said, not all Curries are the same.. Hooking up a pack in parallel to the original pack only involves accessing two wires- the two that feed the controller from the original battery pack. Grab your new 24v pack of the same ah (as your original pack), hook the pos to pos, neg to neg, and thats it for wiring. You can even keep your existing charger setup. Will just take longer. Or buy a 2nd charger and hook those up in parallel too. Hardest part is figuring out how to mount the extra batteries.
