Livall's venture, their Pikaboost ?

But the other obvious bit, how would the connections for a BMS work ?

Looks like a 6 sets of 3 in parallel ..............

Are there two holders containing 10 cells each, as depicted in the video at 34 seconds, and at 2 minutes 10 seconds?

Two holders of 9, and the commentry does say the battery 'contains 18 lithium batteries'

2 x 9 = 18

Apologies, of course you're right - the top left hole in the foreground holder is square. My damned eyesight...

Cue the enquires on forums like this;

"I am sure there is only one faulty battery, how do I check ?"

So unless the product is fake, they appear to have found a way of contructing the battery pack and contacts in such a way that the 'self replaceable battery' is possible and maybe, just maybe, reliable.

I understand the general skepticism about spring loaded battery contacts, I too have many memories of dualing with the contacts on low current applications such as the batteries that were so common in cylcle lamps from a bygone age;

Did you use Ever Ready bike lights? Take a (badly-lit) trip down Memory Lane

Lighting tech in cycling has come a long way since the Ever Ready of the 70s and 80s. Thankfully

But you do wonder ...........

Lights today aren't as bad as the old NeverReadies, but the contacts and switches are still often pretty awful. And Bosch don't seem to have cracked reliable rack battery contacts, or Intuvia display contacts.

Agreed, I still get battery contact issues with torches etc, so I presume that problem has not gone away.

So what possible invention have Licvall invented ?

I can't remember the last time I used D cells - even when I needed them for a randomly wagging rat tail under a blanket toy for my cats, I used AA>D converter sleeves.

I think it's mega-strong magnets holding surfaces together, but time (and reports of riders stuck to lamposts) will tell.
