4mm Female to 5mm Male Polymax Connector Adapter - 2EA

Many high C rating hard case battery packs are moving to 5mm discharge plugs but there are still people who have

4mm packs who want to use both pack types.

This adapter will convert your 4mm Polymax or banana style plugs to 5mm allowing them to be used on the latest generation

hard case battery packs.

So if you are still using 4mm plugs but want to get the latest technolgy packs, such as the Turnigy Ultimates,

these adapters will make that change even easier.
