Battery Adapter BLN-1, BLS-5 and BLH-1

There are applications, where battery capacity won’t keep long enough. Sadly, Olympus doesn’t provide a cheap and simple solution. For cameras, where battery grips are not available, there is no possibillity at all, to provide external power.

That’s why I developed the BLS-5, BLN-1 and BLH-1 battery adapters. They allow to run a camera from an alternative power source. This may be a strong battery or a power cord, as long as it matches the electrical specification of the camera.

There are no electronic parts built into the adapters. Only the plus and minus contacts required to provide power to the camera are connected. A power supply therefore has to ensure proper polarity and voltage. The adapter is not suitable e.g. to charge batteries with the Olympus charger.

The adapters are fitted with a 5.5×2.1mm low voltage power plug. Plus is connected to the center pin, minus is connected to the outside case. A do it yourself version of the adapter (loose parts, contacts to be soldered) is available on request.

The adapter housings are manufactured in 3D filament printing. A gold plated PCB is used for the contacts.

I designed a cap that protects the BLN-1 battery from short-circuits. It also can be used as a marker to signal full or empty batteries. Feel free to download the STL file and print it in 3D.
