Expanding Pedelec (U3 Capacity) via old Scooter Battery

I now decdied it's time to fix the range of my U3 (refurbished) 320 Pedelec by outfitting it with my old E9T Zwheel Scooter battery. That scooter has worked well for a year and it has the best range of any of my vehicles ...

So lets see.

1.) The new battery should fit the 36V criteria. The E9T's does just that.

2.) We need to get it out. enter image description here

.. pretty beefy. enter image description here

But the eBike has limited space in its frame (xxxx cm) So we need to remove the actual battery /accu from the shell: enter image description here

There is too much plastic.. ngh... Cut it down and.. Still won't fit enter image description here

Lets apply some gentle pressue a bit (and remove the foam around the accumulator to make it go in better... (No hammer or impact force ! Cells are suceptible to these things !) Almost done. We need it to go in further !

A little more convincing , using the scredriver to move out the plastic and pliers to remove the upper parts still blocking entry aaand: It fits ! it finally fits ! Yay ! *dances

Ok. time to close it down (thankfully I had remembered the exact way this connector goes as it was on a picture of mine from yesterday): Closed

Good. All done. Lets see... -Moment of Truth ... Yes. It turns on...

Ok. It still works. But.. only 4 bars ? ([]----) Hmm. Maybe this will be as terrible as yesterday with the FijiLa -sham-30000mAh Battery...

This on sports a 10Ah at 36 apparantly. (I can then get the charger port from the Scooter and lead it outside easily. -IF- it works.

Time to do a test drive. There are really only two options: a) Battery will last as good as with my Scooter (that cone easily handles 25+ kilometers with slopes and hills no issue) or b) like with Fijila: Die after 6 kilometers. The display literally went out. No staying on 1 bar. Ugh!

Homeautomation aka. "How not to lock yourself out..."

.. when you forgot your keys.

Most rented homes have two doors:

a) Main- Front door

b) Appartment door

And if you walk out of either and the door closes shut (Wind Oh Wind !) then: Yay !

So. For "b" the appartment door, you can install a fingerprint lock (got mine for 70€)

And a ? You cannot change the lock. As other people living in the same appartment complex rely in that lock.

But you can, rig your remote door buzzer: Cue "National Treasure - Preperation Montage Soundtrack"

And then the software (which you will freeze with Shizuku and Hail once done (as rooting is something my smartphones nolonger deserve): Shame this requires logging in to the software to be able to add the remote, but I was able to trigger the clicker without
