Over the past year or so I’ve been looking into building an esk8, and have done a decent of research and looking around, some successful and some not so much. My build is composed of:
Turnigy Aerodrive SK3 168Kv motor (single motor)
36 inch cruiser deck from Amazon, with Caliber Trucks and 83mm Flywheels
VESC as the esc (ofc)
Pulley and 12mm belt from Enertion
Motor mount from ebay
My only real struggle is with the battery. I am planning on getting a 12s setup, but I’m not sure whether to get a lipo set up or a Li-Ion setup. I’d like to have 10,000 mah capacity because distance is more of a priority than speed. I’ve been looking at the Multistar High Capacity 10000mAh 6S 10C Multi-Rotor Lipo Pack and putting them in series for 12s, but the C rating is rather low. I’ve seen a lot of people using lipos with 20-30c’s, so I don’t know if the high mAh will help with the low C rating, or if a higher C rating would be preferred.
I’m planning on using a lipo charger for the lipos/li-ions and may be eventually wiring up a BMS with a switch and charger just to make charger a lot easier.
Another thing I’ve been looking into is using 18650 cells, but the capacity isn’t as large without requiring a lot of cells and putting the cells in parrell (to add up the mAh) and in series (to add the cells).
EDIT: [For the Li-Ion option, I was thinking of buying 48 2500mAh cells. I was thinking of wiring them into 3s packs. Then wiring them into parallel to double to mAh to 5000, then wiring them into series for a 6s pack, then putting those into parallel to make the mAh to 10,000, then wiring the two final 6s packs into a 12s setup.
3s 2500mAh + 3s 2500mAh (parallel)= 3s 5000mAh, doing that until I have 16 packs. Then combine two into series to get from 3s to 6s for all of them. Finally, wire the 6s packs into parallel to get two 6s packs at 10,000 then wires those into series for 12s. Then wire that to a BMS with a charger port and switch.]
Here is what I think the 12s pack with the BMS and charger schematic should look like;
If anyone can help with a solution that wouldn’t be much more than two of those Multistar lipos, it would be greatly appreciated! The only problem with the Li-Ion is finding that many cells, wiring them, and doing it succesfully, if anyone knows where I can get that made for me that is also be awesome! Thanks!
