As those of you who own DJI Mavic Mini's know, you cannot store the batteries in the charger with the terminals connected. This leave you with 2 options which are:
I designed a battery termina cover which slots into the battery charger and keeps the terminals separated to the battery. This solves the issue of storing the batteries in the charger and also maintains a small profile. This is specifically designed to work with a Mavic Mini 2 but if the chargers and batteries for other iterations of the Mini remains identical, this should work for those too (I do not know what the differences are in batteries between the various models).
