@chaka Majority of the packs are just used, not sourced from recycling facilities.
I already have a very similar setup to what you are suggesting for the discharging of the cells. I discharge a large amount with an iMax B6 then i have a couple of 4 slot independent chargers that will charge them back up and tll me their capacity. So far i have processed around 50 cells and found about 44 usable cells.
Sounds like you have done your research! @laurnts he will be able to output close to 1500 watts continuous with bursts well over 2000 watts in a 6s13p configuration. Most riders never use this much power.
@seanpain4 Ridiculous is always fun! I love the idea of using upcylcled laptop batteries, I’ve seen folks do it for their bike packs and think that’s it’s both cost efficient and a nice way to use stuff that would otherwise be junk! It would be a great contribution to the forum here if you documented how the build goes, what you have to do, etc.
The main item i am waiting for is my Hot Glue Gun. Once i have that i can begin assembling my batteries.
By the time i get the batteries done, the other components that i am waiting for will arrive, these are, Motor, ESC, Controller/receiver, Pulley belt, 10AWG wire, along with some bullet connectors for the Motor to ESC. These are all due to arrive in the next week, maybe two weeks.
This is the board I’m going to use, bought it online from Awol Sports. It was pretty cheap and well made. I don’t particularly like the branding on the grip tape or under the deck so i am planning on repainting it and putting new grip on.
The trucks were originally mounted in a drop through style, but i will need to mount them under the deck as shown in the image. But as a result it leaves that hole there in the deck which i don’t really like. So, as per @treenutter suggestion, i am going to fill the hole with some form of epoxy or resin. Then i can repaint the deck with my own design and then put some new grip on. You can see a close up below.
Change of plan again. Instead of filling the hole with an epoxy or resin, i am going to get a cap 3D printed with the assistance of @Danpooed. I decided to go this route as i will be able to convert the board back if i ever decide to get a different deck. I will also be able to mount my XT90-s key loop on there as well so i dont have to plug it in underneath.
I measured up the holes and came up with a 3D model using 123D. @Danpooed also assisted a little bit with this as well.
Good idea. If you’re running wires to the caps, you might as well integrate a USB port or LEDs in there for night riding. Hell, you could squeeze a voltmeter into the cap to better monitor your range while riding.
I’ve seen this deck online. What are your thoughts on the flex and the feel under your feet ? It’s the grip tape good ? I think the shape might be goof for the oversize wheels we tend to use on our E-Boards.
For me the flex is good. I wanted it fairly stiff as i will have batteries running most of the wheel base, but also to have some flex for comfort. I am only light though (61kg).
Grip tape is pretty good. But i will most likely replace it as i don’t like the logo on it.
@Chris_KP I did the wire mod to my SK3. I used about 8cm lengths of black 10AWG Silicon wire.
I think it turned out pretty good. Only issue i had was scraping of the enamel coating on the wire so i could solder to it correctly. Other than that, no issues.
I am still sorting and testing cells. I am going to start building my packs when i have all 78 of them so that i can distribute the cells evenly, to result in even capacity packs.
This pack that i build was just made out of lower capacity cells and is a 6S2P pack. I needed some power source to power up all my electronics to make sure everything was working correctly, and i wasn’t going to use those cells for anything else.
This is basically what my 6 proper 1S13P packs will look like, just with one extra cell in it.
