+ how do i charge lithium batteries?
( series setups, parallel setups, variable series/parallel setups, chargers, cell monitors, BMS, etc. )
+ how do amps / volts work in a motor?
+ lithium battery common questions
( what is C, AH, S, P, etc )
( battery lifetimes )
( battery voltages )
( battery care / caution )
( examples of various setups )
+ How do the parameters in infineon controllers work ( knuckles has a few posts about this, but they are not meant for a newbie, surely someone can take the task of elaborating on this )
+ Controller options
( sensored, sensorless, brushed, brushless )
+ DD hub motors VS geared
( reliability, freewheeling, weight, power limits, preferred voltages )
+ Front motor VS rear
( suspension forks, aluminum VS steel, torque arms, torque plates )
+ Wiring / electronics
( electronics 101, connectors, wire gauge, pre-charge resistors, etc. )
+ Bike parts commonly used
( tires, freewheels, freewheel cranks, suspension, brakes, cranks, tubes )
+ Miscellaneous
( battery mounting, DC-DC convertors, lights, etc )
I read ES many times a day and these are the questions i see. The answers are always hidden deep within random threads. It would be easy to cobble the stuff together.
