I could reduce this a few pounds if I removed the Davega, swapped the DV6 for the Xenith, put on 6" tires, and maybe lost the nanuk case entirely. Maybe get to 14kg / 30lbs. But I canât see how anyone can really go lower. I specifically choose all the lowest weight mtb components for this build.
But otherwise, itâs pretty light with that 12s2p P42A pack. Somehow it feels lighter than my landyatchz 10s4p P42A / BN M1 gear drive / TB110s at 12.6 kg (27.8 lbs) - maybe because the bro + matrixII is so much longer and wider.
Test fit the 12s3p range pack. Fits nicely above the makerx on some 100% solid printed angles. I need to add some padding, but I think this will work well.
I wouldnât call this Nanuk 905 small, haha, but itâs a nice size. Iâm sure I could pack a bigger spot-welded battery than this NESE setup, but itâs fun to assemble these.
Mainly, I didnât want to have to run wires up the lid for a lid-mounted esc. I also wanted the potential to add a bottom mounted aluminum plate for rigidity and heat dissipation, if necessary. And I wanted a nice little electronics & wiring compartment, so I didnât have to agonize over routing like on a bottom-mount enclosure.
Oh thatâs the only stuff i use! so satisfying to see the adhesive bubble out and know the connection is extra protected.
On this harness i was worried that the large change in diameter from two jacketed 12awg wires down to one xt90 terminal would be too much for this size heat shrink, so i filled it with silicone as well.
LOLâŚit is definitely cool to watch.
One thing to consider is that the silicone needs moisture to cure and the silicone inside the connector might take days and days, even weeks if ever, to finally cure.
It needs the water vapor in the air.
No air = no moisture = no cure. Inside the heat shrink itâs essentially the same environment as inside the original tube of silicone.
There would be verrrrry slow migration of water vapor through the silicone exposed to air but I think that significantly slows down or stops after a while when the exposed silicone fully cures.
Can confirm, tried to do a similar thing between two small, nonporous surfaces and the center was still liquid after a week
The figure of merit is the distance the volatiles need to travel through the bulk material, I think. So maybe half an inch in this case. Thatâs pretty far by silicone standards
Still a long way for moisture to go to make it into the center of the heat shrink tube though.
You do have less silicone to cure but the smaller opening at the end, because the shrink collapsed down, limits the amount of moisture that can get in at any one time. I think there might be some balancing each other out (silicone volume vs moisture entry speed) going on here.
Actually, putting silicone in a very humid environment or in water forces the surface to quickly skin over and seal out moisture that is needed to seep into the rest of the silicone. It significantly lengthens the cure time.
Do you mean air? Or am I about to learn somethingâŚ
