    Extreme moded 18 Fet Lyen Controller

    I been working with the 18 FET controller to see how far I can take it My goals are to remove current from the PC board.

    Lipo support frame

    I built this frame to hold my 24S3P 100 volt @ 15AH battery system made from standard 5AH 6S packs The frame is built but I'm showing the cad drawing I'll show the real deal once the batteries are in it. The bottom is closed cell foam to protect the cells. Mark

    testing made easy

    I finally came up with a way to test the system under load without riding the bike. I don't know why I didn't think of it sooner. Of course you have to be careful not to pinch or otherwise damage the wires. Using the wind trainer worked great. It pulls about 12 amps at 24MPH. I have a better...

    Fairing Report

    So far the windshield has turned heads and generated attention but that's it. I've passed police cars but none have pulled along side me. I've ridden it to work twice. The Hybrid sticker helped, cars have been much more courteous. I couldn't believe it at first but after almost 40 miles of...

    Boost battery

    Does the circuit below, using a brush motor give a voltage boost hence a speed boost without damaging the BMS circuits in a LI-ION pack. My concern is that the FET controlled BMS current limit not be damaged by the higher voltage. Thanks Mark
