@barajabali, your own backpack battery is a smarter idea at that. What happened to that project anyways? 
Cheers Bro. 
This is it minus the power supply. I turned that into its own project which connects to the backpack I ended up buying a new backpack so it wouldnât have the huge hole in it.

Itâs actually super light. Feels about the same as when I carry around my 7 amp charger and tool bag. Itâs aboit 14 lbs or so. 12s9p
It connects to all of my boards but mostly,
I use it on my 4wd direct drive trampa which has about a 400wh battery on board giving me 10 miles with the board alone. Coupled with this 1.2kwh pack I get about 30 miles with 4wd

@barajabali, Wow!! âŚand I thought San Franciasco streets were the only ones like that. Wish not all are like those in Chicago.
Or get a backpack with batteries with a quick disconnect connection in case you fall off. Itâs added weight on your back but it would probably be way more convenient than a trailer.
Lol should have read this before I made my post.
This has a 10S2P 26650 12Ah 444Wh pack with a 15A CCCV charging system and can charge the board main battery pack on the run . On my AT wheels it extends range by about 35km .
Will do a build post if any interest

Wowwwww⌠so much rangeâŚ
Yes we all like juicy build pics. Specially involving batteries. 
Does this charge while you ride, through the bms?

yeah - just charges through charger port
How does it affect the handling with all the extra weight up top and at the rear?
its about 1.8 kg total weight - no noticeable difference in handling
I want one badly. This thing appeals to my inner kid. How come nobody here has done it before? It makes AT wheels legit AF.
Imagine riding a freakinâ mini Hummer!
