Here is my build.
I made some mistakes in buying because of my impulsive habits.
1) I should have made one big order from HobbyKing, instead of 3 different orders.
2) I should have bought a battery package from em3ev.com, ebikes.ca or any other reputable online company.
3) Again one order from Lyen instead of 2 orders.
4) MXUS motor I should have ordered in the rim.
5) Should not have purchased a $15 Alex rim + $15 s/h, impulse buy, but its not wasted, will use it for a powered pusher e-trailer build.
6) I could have bought a better charger, I think those iChargers are the way to go, Dual Channel.
7) With the better charger however is a better Power Supply, hence more money. But those desktop power supplies would have worked just as good, plenty laying around. Computer stores chuck 'em in the alley in disposal bins. Google can help you convert one for sure.
Here is what I have learned from diving headfirst into a DIY ebike build.
1) Should have bought a 1000W rear 26" ebike kit from yescomusa, then batteries as mentioned previously.

Here is a list of stuff I bought.
MXUS 3000W V2 motor only, right from the manufacturer $295 delivered to Canada + $16 in customs.
Canadian Tire (In store buy) - Multimeter $10 or $20, was on sale for 50% off
Canadain Tire (In store buy) - Digital Measuring Calibrating Thingy $10 I think, on sale as well for 50% off.
Princess Auto (Its exactly like USA's Harbor Freight, except its a Canadian Company)
- Adjustable Heat Soldering Iron 5W-60W with 3 tips - I paid $10 (reg $20) + $6 s/h
ebikes.ca - 26" Downhill rim 31mm wide 36h $56 + CA3-DP $68 + 3way switch $9 + $27 s/h
Lyen.com - 18 FET Low RDS MOSFET Overclocker Ready LYEN Controller $199 delivered + USB-TTL programming adapter $15 +

Just ordering my 3rd shipment now....
12AWG black/white, more 4mm bullets with housing, parallel balance board,
Some other notes, for personal reference, need to buy some Denatured Alcohol, Acetone or Methyl Hydrate to clean bullets after soldering. Desoldering braid, thicker solder.
ebay - 3 prong power cable for power supply $5 + $5 s/h
local community bike store - freewheels $5 each, basket $5, kickstand $5, seats $5, pedals $5, bike frame $30
Seems like a daunting task with stuff everywhere.

I would like to add a few words of warning. Just because.
----------->>>>>>>This is pretty serious stuff, it can be deadly and extremely flammable, it can melt connectors, batteries can explode, and it could kill you or someone else. Limbs could be lost. Always Always Always use caution, Always be safe, Always do and make things safe! Always get help from professionals! Always wear protective gear and P.P.E.!!!!!!!!! ALWAYS !!!!!!!!!
Have to think about what amperage the wires will be having. I have not found a solid answer on it yet. There are some charts kicking around ES.

So for a battery pack buildup I will be doing a 20S3P which equals 74V and 15Ah using 5x4S1P hardcase batteries from HK. Might go 24S3P, still pondering it.

This schematic was one of my originals. Each series string, are connected to each of the parallel branches to give us 20S3P.
