What kind of connector is this? - Looking to do a Bosch tool battery mod

Hello forum

I got myself a Brompton electric conversion kit and am about to do some 3D printing and making an slide-on adapter for bosch 36v tool batteries.

I bought the Brompton conversion kit from the Spanish Ciclotek.com. Great customer support btw.
For the Bosch battery adapter, I want to use a xt60 connector to the battery connector on the controller. I have attached pictures.
The company have their own battery solution, but I rather tinker with my own setup, I just don't know the name of this connector? On the site of it, the text "DREAM" is written.

Also, sorry if I broke any rules or posted the wrong place.

The connector I am not sure about, however I am interested in the use of the Bosch powertool batteries on a Brompton.

I have recently converted a Brompton to electric and using a 10S1P Samsung 21700 battery I ended up with a working eBrompton weighing in at 11.8Kg. The 5Ahr battery I have found to be fine for the normal trips I do on the Brompton.

I currently have the battery and controller in a handlebar bag facing backwards so that the bag can stay in place when folded.

I am planning to move the battery and controller into a bag to be fitted to the Brompton front bag block. My idea is to use one of the brackets below to take the weight of the battery itself, and then surround it with a handlebar bag and this bag wont then end up needing to take a lot of weight, just the controller and spare cables.



Now when the Bromptoon is folded the bag will be in the middle and facing updwards, which makes wheeling the folded Brompton a lot easier.

What interests me about using those Bosch power tool batteries is that if there was a suitable connector mounted on the bracket above the batteries would be readily removeable and then instead of keeping and charging the bike in the shed, I can store the folded Brompton (without battery) inside the house by the front door where it is more secure and quick to get out and about on.

Here is a picture of a Charger you can get for those Bosch powertool batteries, its they are about £25 from the far east.

The plastic bit that contacts the battery and holds it, with the 5 metal prongs, looks a slightly different colour to the body of the charger, wonder this holder is removeable ........
