What's inside the Exway Aux Pack? (Unbox / Teardown)

[@jdhaggard562]

The strap is very standard here in China. Almost everyone I know has an expanded diy battery on top their boards and uses a ratchet strap to keep it in place. It's reliable, simple and not permanent.

[@RBEMotion]

Ah nice! There are plenty of DIY guys here that use that method too. I prefer more elegant or permanent solutions, but in a stiff deck like this with a great mounting point, it seems to perform really well.

[@uhjyuff2095]

Your packs look great but you have to remember Exway using those extra two wires out to the output leads makes the bms monitor discharge. Until the custom boutique boards have bmses that are not bypassed riders will be left with a risky battery no matter how well the battery is made.

[@RBEMotion]

Well if you were to use this battery on a diy, I think you would probably just use it as a swap pack rather than having it plugged in at the same time as the other. Besides, most people aren't building with these lishen cells either, so the load sharing wouldn't work properly

[@uhjyuff2095]

@@RBEMotion Correct, the two "data" wires would having nothing to plug into on a DIY board. The BMS inside the AUX pack would be not be operating as the manufacture intended so it would be "DO AT YOUR OWN RISK" at that point.

[@RBEMotion]

@@uhjyuff2095 Yeah I'd agree with that. Unless they explained how to properly interface with those two wires, it would be hard to utilize to its fullest capabilities

Great in-depth HQ vid that'll help anyone looking to get this AuX pack. I'm curious as to how 23 lbs. strapped onto the center of your board will affect the ride.

[@RBEMotion]

Thank you! Surprisingly, it actually make the Atlas pro more enjoyable for me to ride. It seems to dampen your input a little bit and you can definitely feel it. Depending on the weight of the rider, you may like it, or dislike it. Amongst the riders that tried it on our track, I'd say about half liked the feeling, the other half either didn't like it, or would think it needed some adjustment. I will say, since this board is so high off the ground, you can notice it more than on a mountainboard with angled tips and the lower center of gravity. For me, it's been great though and I don't mind the extra weight up there.

[@PatrickECleary]

I wonder what kinda signals are going along those BMS data pins. Do you have an oscilloscope to probe into them with while it's operating? Granted... It'd be a challenge to get contact with them while its all plugged in. Perhaps under the deck cover theres a way to sneak a probe in?

[@RBEMotion]

Man I am super curious too. I don't have an oscilloscope quite yet, but it would certainly be interesting. If we were able to figure out what they do when the board boots, or when you're discharging, it could help DIY users figure out how to make an AUX pack of their own.

[@Ragedrum1]

thanks for the video bruv - btw you mentioned you are 3d printing parts. i would be happy to know if they are exway atlas pro parts ;P

[@RBEMotion]

Glad to be helpful! I do have some parts that will be available for Atlas Pro soon. I sell tail light mounts and tail lights that will work with the gear drive version currently, but I'm also working on lights implementation! Check out pevcomponents.com!

How difficult would it be to swap the esc in the atlas pro? I understand the aux pack is self balancing. But what kind of tuning is done to the esc if any to allow u to add and remove the aux pack as desired? What are some things to concider?

[@RBEMotion]

Swapping the ESC isn't too terrible, I think it comes out with a couple screws. However, you may have some trouble fitting in an alternate - I haven't tried it yet, but maybe the Makerx M100 or DV4s would fit. You'd need to replace the motor connectors and sensor wires, get a new remote, and probably modify the enclosure a bit. It's definitely possible though. As for the Aux pack, the ESC does not communicate with it at all. It's the BMS in the Aux pack to the BMS in the board battery, so you don't need to worry about that part.

[@omaid7659]

can you please provide a link for your solder and flux?

[@RBEMotion]

Links are generally not great to have in KZbin comment sections - but the solder I use is lead free Kester solder 63-37. Flux is made by alpha metals and both work great!

[@siulrosales]

do you think it’s possible to add a diy aux pack to the exway atlas

[@RBEMotion]

Well. Complicated question persay. I think it is "possible" but it would not be as integrated as this one, and it would be pretty difficult to interface if you didn't already have the aux pack lid / connector. I actually recorded a video installing the aux pack and going into the connections, but I haven't gotten to edit it yet. I think, if you made it so it was a "swap pack" and it didn't share load with the internal one, like this Aux Pack does, it would be possible. Maybe I'll try it someday if people are interested but it would be tough to reach the polish of this delivered product.

[@dieselphiend]

I guess they don't expect to ever have to vent. Makes you wonder.

[@RBEMotion]

Definitely does make you wonder, however, most of the packs we build completely block cell vents with nickel anyway. Not saying that this is better or worse, because I'm not really sure, but it's a problem on most esk8 packs. I would expect that being completely potted in resin might take it longer for you to notice if a cell were to go into runaway. At the same time, it's usually a huge panic moment anyway - maybe having a strong metal box like this will help you chuck it outside?
