Lock-On Battery Booster beta

I like the small size and weight of the unit. It powered my 24v Moviecam SL fine with my 28.8v BlockBattery 2F1 batteries. I have not tried it yet with my 14.4v batteries. I think the mounting bracket could be improved for more rigidity, as there is some play with the current Cinelock system. Perhaps you could add a few more mounting bracket options that use more of the existing screw holes and have a larger surface contact area with the Battery Booster. Also, it would be nice if the d-taps were 12v regulated, even if you had to make the device a little larger. When used with 28.8v batteries, I measured the voltage of the fully charged battery at 30.5v which exceeds the input limits of many common accessories. With 14.4v batteries, this is not an issue. I have ended up labeling my BB d-taps with warning labels.

Amazing Solution for a Unique Problem

Absolutely amazing product! I was unable to re-cell my ARRI 235 OBB-1 batteries due to them being discontinued for many years. However, I still wanted a camera mounted battery system. Alan and I went back and forth on designing the 14v to 24v booster for a couple weeks. Alan engineered and produced a fantastic solution for a modern battery system for film cameras. I can honestly say this was well worth the time and investment. The booster arrived and I could not wait to test it out on my 235 camera. I paired the adapter with some Anton Bauer HC Dionic batteries and can confidently say my camera can run from 1fps all the way up to 60fps off of the battery booster, efficiently. It was such a phenomenal experience from the very start receiving the first drawing, all the way to the final product delivery. If you need a camera mounted battery system for your ARRI, Moviecam, Aaton, or other 24v film cameras, this is the solution for you! PS: the adapter utilizes a 16x9inc Cinelock which mounts to the side of the camera’s 2 pin accessory mount.

Amazing device

However I don’t like the single screw adapter. Two at least would be idea. Internal thread of the housing would be great. The single screw allows the unit to slide with the heavy battery attached.
