I received your battery backup and soft case. I'll have to say that both products are quality especially the soft case.
Your current battery pdf file needs to be updated to display the new battery (at least the one I received) due to not having the USB pport from which the picture seems to have. I haven't seen the one which is pictured (it appears to have the USB port). Mine came with a power cable which plugs into the battery. The other end plugs into the iFly battery connector. Also, the iFly battery to power connector come with an RF choke, which neither the battery instructions nor your documentation lists. I wound 3 turns of the power connector wire (close to the battery end) around the choke. Not sure if the choke is used to keep radiation from the iFLY or the battery. So, it would be helpful to know which end of the battery to iFly power connector to have the choke closest to.
Nice product addition by the way.
The case is very well padded and has two zippered pockets. Enough room for both the iFly and battery or for any additional " whatever" items.
