Spare batteries from Brompton can be an issue yes. There is a conversion kit available for the G-Line that uses Bosch power tool batteries on the front bag block, you can get those batteries all over the World.

Brompton G-Line Electric with a spare battery ? The non Electric I have, folds quick and easy and small, very nice to ride, more like a full size bike. Even has hydraulic disk brakes.

Provide links to the kits you mean maybe ? One kit on the Woosh site shows a battery mounted on the front bag block, the other is battery in a bag mounted on the steering tube ................

Does the controller you are using read the temperature sensor comms from the Bosch battery and cut power if overheating is detected ?

Yep, does look pretty standard stuff, not sure about the battery connector though. But the Brompton is rim brakes on meagre 16" rims, so instant death on an electric bike, given some of the 'advice' I have seen ....................

Well the battery\controller mount on the front bag block does look better than the TOPBIKEKIT setup; Difficult to comment on the rest, the bike shown is not a geniune Brompton, so who knows if it fits on a standard Brompton. The other issue, when buying from the far East, is to know whether...

At the start the guy says its about a 'global classification for electric mountain bike motors'

Wonder if the powers that be will also include a category for 'dangerous walking' in the new legislation ? These days, especially on cycle paths, large numbers of pedestrians no longer look where they are going as they are constantly staring at phones and random changes of direction are the norm.

The version with rear rack and roller wheels is about 15kg. The fat tyres do look 'cool', especially for social media posts etc, but they are a bit thin. I have fitted Marathon plus 20x1.75 tyres, adds about 500g to bike weight but I wanted good puncture resistance. The supplied Schwalbe...

Well, I have one, and it does ride very well indeed. More like a full sized bike really, completly different to a 16" Brompton. Much much better on pot hole infested roads. Its not as good in commuter bike mode, as in carrying on trains and busses, as the 16" Bromptons, but it still folds...

If there were a generic slide in style electrical battery\controller connector pair it should not be difficult to fit it to one of adapter plates that allow stuff to be connected to the Brompton bag block.

How does that bag deal with the electrical connections ?

Well, I built it that way so that the battery\controller bag could stay in place when folded for rolling around shops etc. Also if you keep the bag small the bike does not really look like an electric. Not sure I have seen a separate clip on clip off battery\controller bag, that you can buy, in...

Its a shame you dont seem to be able to buy that ratchet insert (see first post) seperatly, it would be a useful addition to the toolkits I have on the Bromptons. I dont normally carry a ratchet driver, a simple angled one like below is OK for out and about use; On the Bromptons I have...
