    EBayEV setup questions...

    The marine tandem chargers have only one transformer w/ a common ground side but two independent charging circuits. Could get away w/ one set of isolation relays, but its only pennies to isolate both sides. The present SW190-100 contactor has both sets of contacts wired in parallel and it's in...

    EBayEV setup questions...

    Hi All; Got a few questions now that I'm putting things back into the car........and I imagine I'll have a lot more... The setup is 10 12V batteries in series....they were originally wired w/ size 1 cables......the motor is an ADC 9.1" and the original controller is the Curtis 1221B (400...

    New EV from EBay !!!!

    The equivalent Valence pack would be 28 times the cost of this surplus Pb pack..otherwise it looks promising...hopefully by the time these need replacement there will be a viable alternative...meantimes, I'm looking to maximise the life..parallel charging etc etc...maby a capacitor bank as...

    New EV from EBay !!!!

    Just thought I'd give a quick update while I had the chance..... The surplus batteries (10 AGM SLF-12205's by POWER battery Co.) still check out despite age etc.....we'll see how they behave in real charge discharge this spring The parrellel charger bank made of 5 dual marine Dytek 15 amp...

    The brakes and pads are new but the pads are the plain black ones.....first try will be better pads....that's a great site....... Better weight distribution is going to be a must......I'll need to figure out how to keep it more "stock" looking.......

    On reflection: 1. I probably should have been moving before opening full throttle...... 2. Lucky to be wearing a helmet (esp at 64 yars old) 3. 4 21Ah SLA's in soft bags at the rear (not to mention rear hub motor) would seem to be the source of both difficulties......rear CG shift and...

    First test flights of the 48V version this afternoon.......Yes, it will really do a "right over backwards wheelie" w/ the 60 lbs of batteries in the rear (OUCH!).....and yes, it needs significant damping to keep the steering from going into oscillation at top speed (managed to just recover from...

    Brushless Boat Motors and Electric Boats

    The thrust requirements of (even a good sized) displacement hull are quite small at displacement hull speeds...........and boats sit in the sun all summer, even when not being used.......been there, done all that years ago w/ tiny gas motors and tiny (by today's standards....~ 2 sq ft)) solar...

    Shakedown cruise was this morning.....everything ran nicely at 36VDC.......shook up the locals across the street when I pedaled up their steep hill sitting down......they're still shaking their heads till they figure it out! It was very popular w/ the kids (ie under 40) here at the...

    The LB37 looks exactly like the one I have except upgraded to 48 volts...in fact I like the looks of that so much I just bought one ! Now I have to go back to EBay and find a charger !!! EDIT: Ok...so the new pieces on EBay order are: 1 48V controller...LB37, and one 48V 4.5A...

    Yes, that is a brushed motor (steel gears) Lessss has one...I think they are just the ubicquitous scooter motor.......looking inside, I don't think it will do 48V...back to EBay !

    Motor is the Heinzmann rear hubmotor 500W (up to 750W)...not the "racing" motor Batteries are 3 PowerSonic PSH-12180NB-FR 21AH....about 10lbs each This controller is the cheapest thing I could find on EBay ! A used (and apparently sunk) JC36 from YongKang Jiangchuang Electronic Factory.

    Gozilla lives !!! First test of whole system today....all works ! Now cleanup of the wiring and it's on the road......3 batteries may not be optimum as it unbalances the bike to the heavy side when on the stand.......may just have to go to a 48V system..tsk! tsk!.... :lol:
