You may need to monitor cell voltages to see if you're losing a cell. Have you noticed a reduction in range or pack capacity?
If you hit the pack voltage LVC then yes you're risking overdischarging a cell if you don't monitor individual cells.
If you hit the cell voltage LVC looking at...
Trying to find an inexpensive and simple way to power a DC motor and other 12v controls from a 120v AC power source. The project is refurbishing a robotic scarecrow for a display, it yaws using a brushed DC scooter motor. I am assuming the motor may spike 150 watts at 12 volts.
My idea is to...
Not sure how to word it in google to search for it.
I just started having problems, my e-trike wouldn't run, assumed the controller faulting because high throttle on start up because the old razor hall thumb throttle was putting out 2 volts at 0% throttle, so I could disconnect the signal wire...
Just wondering about the shock and fatigue of hard mounted electrical boards experienced on a high speed bike, the bone rattling harmonics. For heavier electrical components (opposed to 0603/0805 passives), would using through-hole have an advantage regarding durability. Can the copper pull off...
It definitely looks unique (ugly IMO). Seems like there is a big waste of space where you could lower CG and/or add more battery cap.

Great to hear you didn't get broke. Most drivers where I live (99%) do not ride bicycles or walk around; so naturally, they have no concept of what a pedestrian is, what they do, and most importantly when to look for them. People always pull over cross walks while you're trying to use them and...
It sounds like you have a good idea of these issues.
Corrosion like oxidation, electrochemical processes (H2O+minerals = electrolyte) and damaging your pack's structural integrity (ie. wet duct tape) would be more of the enemy when it comes to getting your pack wet. The packs should be well...
HeHe, we all have our guilty pleasures. Last summer I built a HF Predator engine for a friend's minibike, upgraded bigger cam and valve springs, baby harley: http://www.youtube.com/watch?v=xPg66HQiV8w
Gas power? That's Blasphemy! I got 1150kwh of nano-techs to get it started. It's on the bench right now getting aligned, but here is a side image with swingarm/motor installed: http://i.imgur.com/QWkwEeG.jpg
