I just bought my first lipos and I noticed they look bloated (puffy?) when I pulled them out of the box. Is this visual view enough to determine the batteries are bad and should be sent back? Or, should I check the voltage first?
I have a battery charger (Thunder AC680) and a digital pocket multimeter
but not a watt/voltage meter. Can I use either of these to check the voltage?

The puffy look seems to be packing but check the voltage first by very carefully probing the balance connector checking each cell and if it seems good then see if your charger will accept them. BTW, those are very small for the average RCP plane?.

How do I probe the balance connector? Yes, they are for the [U]FT Nut Ball[/U] (just for starters) since I am so new. I expect to outgrow them fairly fast and pass them down to my nephew who will also outgrow them quickly also.

On my batteries the red wire is the 3rd cell(11.1 volts, yours may be backwards) and the wire at the opposite end of the balance plug is the ground. Black probe from meter goes on the ground tab showing through the slot on the plug and touch each exposed tab in succesion with the red probe from meter. You should have 3.7 + 7.4 + 11.1 or so as you go or just probe 2 tabs beside each other. Each cell should measure 3.7 volts or at least the same voltage +/-. DO NOT LET THE PROBES TOUCH EACH OTHER! This is how a battery voltage checker works.

It doesn't look puffy to me, just looks like the wrapping. You will know a puffed lipo when you see it..
