Hi, it's my first post (but been on these forum a lot) and I'm about to convert a cheap mtb to an ebike. Got pretty much all the major parts and would greatly appreciate some suggestions on how to mount all the electronics and even some critiques on my component choices.
The bike is a Jamis X2 2011. Switched to road tires and added stuff like a rack to make it better for commuting. I already have another Jamis, an XC comp 211, and love it so didn't mind getting another Jamis. Also, it was only $140.
It's a 9C 2806 rear hub motor from ebikes.ca. Great thing about ebikes is that they're located in Vancouver, and minutes away from my home/office. Talked to the guys there a couple times and they know their stuff.
Got a Crystalyte Sensorless 25A and Cycle Analyst as the brains of this operation.
Bought 6 x 5000mah 4S 20C lipos from HK. I liked that they're in hard cases and the price was good at less that $25 a pop. I'll be wiring the packs to be 3s2p or 12s2p lipo cell configuration for 10Ah 44.4V. The 25A requirement should be easy for this packs. I think it's a good set for roughly $150. May decide to get 3 more to make it 15Ah, but I'll try 10Ah for now.
Didn't get a charger specifically for this setup, so I'm just using one that I currently have for my RC stuff. I'll be balance charging all 6 packs in parallel via the board to the right. Later, I might have to get a dedicated charger with a higher V so wouldn't need to remove the battery packs from the bike.
Just for fun, my 1/8 truggy with 2400W+ system and goes almost 90km/h and can pop a wheelie at 50. Initially converted from nitro to brushless more than 4 years ago. I find it funny that the ebike would have less power.
So there's the list. Do I need a BMS? How to mount them? Putting all the stuff in panniers on the rear rack would be the easiest option but the balance would be quite off. Suggestions?
