What Is A Deans Black Box?

Interestingly enough, as I was writing the previous article on LiPo Vs NiMH, I came across a very interesting product called the Deans Black Box. I have little inkling of what is a Dean Black Box, and hence my inquisitive self went to find out more information about it.

To find out what is a Deans Black Box, we should first break down the fundamentals for you. The Deans Black Box is an electronic device that fits between the battery and a discharger and it enables it to emit the battery without the chances of over-utilizing or discharging the battery.

This device shuts down a circuit whenever the voltage reaches 5.4v, while discharging a six cell pack. So you can think of it as a safety device for your RC car.

The Deans Black Box were used for packs of single batteries that were fastened separately to form a pack.

How Is The Deans Black Box Used

Now let’s look at an example of Deans Black Box in use:

First, we got the Deans bulb discharger and slicked the Deans connector and added a Tamiya plug. Then with 6 mAh 3300 stick packs were hooked to see if the packs discharged enough when in use or if there was a change of outcome when put together. Each individual pack was attached to the discharger and surprisingly, the bulbs lit brightly for approximately for a minute and half.

Afterward, each of them was ejected and were charged. In total they covered 35 minutes then we placed each pack inside the car and analyzed an hour runtime to get a satisfactory result.

Put the battery into the black box, seal the black box with the bulb discharger, hit the button and in time you will have an absolute battery that is discharged. For many, it’s not that much of an expensive insurance to halt over- emitting of the battery packs. If stock motors are being raced then you must keep in mind that you need to discharge at 20 amps; that’s equivalent to 10 bulbs. If you are racing a modified version then it is recommended to discharge at 30 amps; so you will require 15 bulbs in total. Remember to always use a battery removable device (Dean’s Black Box) to avert over-discharging of your batteries.

This discharger usually organizes 10 bulbs in an aluminum frame covered in red powder to make sure there is no sort of disintegration. It even acts as an effective car support with the help of foam blocks at the back end. It is commonly available with an easy setup kit, and comes along with a main plug and wire, which is ready to put into your battery packs.
