Stig, I bought myself one of those NOCO Boost Plus battery jump starters for Christmas..will keep it in the car (and will go in daughters' cars when they start driving) but can also use it to jump start motorcycle/scoot. You have room in your top box for something like that if you ever want the additional peace of mind..

Yeah - I've thought about one of those Hawk.
My 2 scoots batteries are behind a bit of a panel, after removing a pair of screws. Not a big deal - unless I'm dead along the road-side 90 mins before sunrise on a windy 27°F country road.
So - do these have a fitting to work with a Batter Tender's quick connect....which I have very easy access to?
Also, I'm looking for an a air chuck fitting that will connect to those stupid 'clip' ends on the business ends of most portable, home air pumps ( and on stand-up bicycle pumps)
I'd like to connect something akin to those brass air chucks found on the ends of red hoses at gas stations. You just press it on the stem and you're getting air. I find those a lot easier to use in the confined spaces of scooter wheels, and around some automotive hub caps.
Winter time is when I go looking around for stuff. Like a new digital Slime air gauge. Mine - the battery is many years old.
In this snowy week - I'd take even a nice, wet, ride!
