Do you mean this?
That is a new bundle, but it is not anything new and provides nothing you do not already have available, unfortunately.
It is simply a battery, switch and cable already provided in the kits originally.
It is not a shield either.
We have (I have) asked for a rechargeable battery that can either:
- Be removable without having to disconnect the battery. This would require the socket or plug to be directly mounted to the battery, so insertion lines up to the matching socket or plug in a model’s design.
- A switch that has a USB socket on it that can be accessed externally (depending on model design) so the plug doesn’t have to be removed from a cable to then connect it to a charger.
