I purchased two Tunigy Nano-Tech 4500 5 cell batteries. The balance plug is so much bigger that it won't fit into my balance board. Anyone out there know what to do?????? I guess that may be what I get for trying to save some money, thanks for any help.

different brand batteries have different plugs...

I have a few different balance boards and interchange them on my charger as needed

Atlanta Hobby carries a bunch

It's bigger because it's made for "standard" asian LiPo 5 cell balance chargers/adapters.

The Electrifly stuff conforms to this type of plug.

What you had may have been targetted to other formats.

What balance board/charger do you have?

I'll bet you can use an Electrifly 5S adapter with it just fine.
