Hi everyone,
Sorry for the noob post but cannot seem to find a good source of info anywhere.. Very lost on the whole Lipo thing. I just purchased a big lot of offroad stuff from a great member here. He's including 2 5000mAh 2S batteries, these ones: Edit - can't post links.. They are team EAM 2s 70C 5000mAh in a hard case (not shorty).
I also got along with it a new Team Orion touch advantage duo. It comes with 2 balancing boards and the ability to charge 2 batteries at once, but now I don't know if the charger comes with the plug to go from the balancing board to the batteries, I understand balancing is a must when charging. Does the charger include the cord I need? If not, which type of plug do I need? There are a lot of confusing types, XH, EH, etc. Do I need different charge leads to fit my batteries?

2nd question - Do I need a battery sack when charging/storing? Is this something tracks require? Does one just put the battery with all plugs hooked up inside of the bag?

Thanks in advance.. This has been very confusing for me, out of a long hiatus!
