Hello, i have post a while back asking for a budget board advice, so now I’m uploading my progress. All the parts have arrived, battery is done, most of the mechanical part is done, just need to wire everything up, draw and enclosure and test it. Oh and find time for all that
I spent around 200-300$ on the board so far, and that’s without the batteries.
Battery Sony VTC5 8S3P I was choosing between upper and lower setup, and decided to go for upper. Soldering vs spot welding Decided to solder the battery because i dont have my own spot welder. Battery temperature didnt go over 90°C during soldering, and since the cells aren’t new and i plan to upgrade the battery,so i decided that i don’t mind losing few cycles on the pack. I cut copper busbars and drilled holes in them with a paper hole cutter for the solder. The cells are glued with epoxy. Pre-soldered bulky wires and wraped in kapton + heatshrink.
All done, wrapped in heatshrink this way because thats the only size i had, and i can double stack battery if i change my mind later.
Pretty happy how the battery turned out. For the next one i will spot weld and use fishpaper.
Motor: KEDA 6364 190KV ESC: FESC 4.2 BMS: AliExpress with 60A discharge, 8Acharge. Drivetrain: Sprocket 14:28, 83mm wheels. Had to 3D print spacers to mount sprocket on the wheel.
Deck is from old Meepo board, donated by @Tinp123 (thanks )
I still cant decide to go double stack or single stack for the batteries. And Im currently working on enclosure that gona be 3D printed in PETG. I want to put batteries and electronics in enclosure and mount that on deck, but deck is fairly flexible so im reconsidering this.
TODO: Wire everything up Enclosure BT module Antispark LED lights DRIVEE!
