Hey guys, after seeing @Heat_Seeker BoardUp build, it inspired me to create my first build base on the BoardUp design. As a college transfer, I will be transferring this year to CSUP where there will be more commuting and hills. I wanted to build something that is portable where I can fit into gym lockers, easier to carry around and still be able to get great range and performance. Majority of the parts I will be using are used from resellers on the eks8 builders forum, Reddit, online deals, and locals.
This will be my first real build where I will be spot welding my battery pack. I’ve previously had scraped builds using meepo battery packs, soldered battery packs, and Chinese ESCs. Please bare with me and help me out because I’m still pretty confused about building the battery pack.
Here are the part list and prices I got them for:
Deck: Rayne Amazon Longboard $10
(Used from a local seller) I will be sanding, cutting, and repainting this entire deck after installing the BoardUp guts. https://www.muirskate.com/longboard/completes/17611/Rayne-Amazon-Longboard-Skateboard-Custom-Complete
Motors Kit: Dual BKB 6354 190Kv Motors + Dickyho Mounts + Wheel & Motor Pulleys + Belts $165
( Bought on Reddit from dollabillplz) I have some BKB motor mounts that I would like to use, but I’m having a hard hard time removing the motor pulleys with kingpins installed. Suggestions? Does a torch really help?https://buildkitboards.com/collections/motors/products/6354-208kv-motor
ESC: Foxbox Unity $200
Got one from the Easter 2 for $400 sale, and was able to split it with someone. https://www.enertionboards.com/focbox-speed-controller/focbox-unity-dual-motor-foc-controller-esc/
Batteries and BMS: 40x Nkon Samsung 30Q Cells $152.03 https://ru.nkon.nl/samsung-inr-18650-30q-3000mah.html
Currently, I have this 10s 40A BMS that everyone knows about. Could I use the BMS I already have for charge-only? What is everyone’s opinion on this BMS from their experiences? https://www.aliexpress.com/item/10S-36V-Li-ion-Lithium-Cell-40A-18650-Battery-Protection-BMS-PCB-Board-Balance/32697273276.html?spm=2114.search022.214.171.1243b16edQe3zb6&ws_ab_test=searchweb0_0,searchweb201602_7_10065_10130_10068_10890_10547_319_10546_317_10548_10545_10696_453_10084_454_10083_10618_10307_537_536_10059_10884_10887_321_322_10103,searchweb201603_52,ppcSwitch_0&algo_expid=9405d967-baf5-4ca0-8a78-80f9d15c6456-2&algo_pvid=9405d967-baf5-4ca0-8a78-80f9d15c6456
But I’m not sure how the which BMS is suitable for this build. I want to go for what is the best bang for the buck. And I have read all over different threads about whether to use a charge-only bms, like the BesTech D140, or charge/discharge BMS, Bestech 80A BMS. Should I be worried about the cells getting unbalanced when using a charge-only BMS? Any feedback will be great!
Remote: Mini remote $18 + AVIO Mod Parts $12 = $30
Will be doing https://www.electric-skateboard.builders/t/the-avio-mini-remote-mod/72074, I have a Creality CR-10S so 3D printing isn’t a problem.
Enclosures: Battery Enclosure $43.25 + ESC Enclosure $13.65 = $56.90
Hardware: Esitmate $50
Was about to get most of my hardware under $50 and already had some on hand stuff like, shrink wrap, fish paper, neoprene foam, bumber guards, shock pads, M4 screws and inserts, etc. I also recently won a $100 to Lowes so I was also about to get some bondo fiber cloth, resin, hardener, loctite, spray paint, and more for free.
