DSF9032 RT Web copy

V-lock and Gold Mount batteries can be expensive and when traveling may be hard to find if you need one in a pinch. Kessler aimed to fix this problem with the Mag Max 3A battery adapter that utilizes a common battery that can be found in almost every country in the world. The DeWalt 20v Max and the 60/20V Flex Volt batteries. The adapter outputs regulated 14.4V 3A on a Lemo 2 pin, a 5.5mm female connector, and a D-Tap connector. The Mag Max 3A also outputs 5V USB charging for devices like a cellphone and accessories that accept USB power.

Kessler’s Director of Product Development Mike Sutton initially wanted to make this product back in 2012 when the 20V Max battery system was released by DeWalt and has finally been able to bring that product idea to Kessler. The Kessler Mag Max 3A is a perfect solution for Kessler motion control users but also for anyone looking for an alternative, reliable and affordable power solution.

Kessler Mag Max 3A inputs

There is a limitation. The Kessler Mag Max 3A battery adapter will not power devices that require more than a 3amp draw but will work with most video accessories used in the industry like monitors, DLSRs and mirrorless cameras with a regulated battery dummy, follow focus systems, wireless video transmitters, and receivers, Kessler motion control systems, LED lights, and more. A 15A version is in development for powering cinema cameras that have a higher amp draw in the 8-12A range.

Battery Life

To calculate battery life using this equation. Discharge Time = Battery Capacity (Ah) X Battery Voltage (V) Divided by Wattage of the Device you want to use with it.

DeWalt 20V Max and 20/60V Flex batteries come in various sizes (1.5Ah, 2Ah, 3Ah, 4Ah, 9Ah, and 12Ah).  When using the Mag Max 3A with 30/60V Flex batteries, it only pulls 20V not 60V but gives you the extended Ah those larger size batteries offer. 

Kessler Mag Max 3A will debut with a special introductory price of $199 USD on the Kessler store Friday, January 10th, 2020 and the price will rise to $249 in approximately a week.
