    Ooops, I overcharged it again ...

    First of all, don`t worry too much, sice I`m talking about a single Lipo cell, only 350mAh, but 15C rated. Long story short, I left it charging at 1C, I came back after 80 minutes, expecting to find the green light and a ready to fly cell, but it was still charging, I quickly took it out...

    InBike URBAN, a cheap italian ebike (made in China)

    It is similar to this, but color is grey! Full alu frame, 26" wheels, shimano 6 speed, LiMn 24v 11 Ah. Full Legal Eu motor 200 watt. :mrgreen: Very basic control system. Extremely light: the battery pack is so light that I was not convinced it contained anything at all, but at the moment it is...

    Aprilia 125 tuareg e-conversion

    Just a placeholder post, not so much beef, for now. Motorbike is similar to this, just a bit more rusty: I plan to modify and repaint the frame anyway, so a bit of rust is not that much trouble .... :mrgreen: Front rim will be reduced in diameter from 21 to 18 or 17, to lower the center of...

    I recently bought 3 packs of LiPO: Turnigy 40-50C 6s 2200mAh ... They came very fast from the German deposit, but one pack refused to charge ... :? I measured the individual cells with a multimeter and they read: 0.1v, 3.9v, 1.6v, 1.7v, 3.9v, 3.9v .... :roll: I guess it is the case to...

    72V 1500W 40A ecrazyman 2011 controller

    Hi to all! I got this controller recently: I'm going to replace fets and then enhance the current limit. I opened it up and I found 12x IRFB4310 fets (chinese copies?), a switching regulator instead of the prehistorical resistor followed by the LM317 ... and an SPMC65SF112A SunPlus...

    36-24-18-12-6 Fet controller STATUS @ 2011

    I'm on the way to get an 'Infineon like' controller for the purpose of driving a MARS ME0907 motor. I understand that either a 24 or 36 Fet controller with upgraded Fet can deal with the motor requirements. I see in the Online Market and in the Forum several choices: Lyen controllers, Methods...

    Dual Controller, Single Stator ?

    chinese-ST 6 mosfet 24v-250w controller

    I wonder if anybody has seen this controller: Inside It looks like this: Is is actually quite similar to the infineon controller, except for the cpu: the mosfet driver circuit is identical to that one. PCB is showing good quality layout, it uses an LM317 for the supply and 6x 80NF70...
