Hello Everyone! I'm new here and a Friend gave me his Ninebot ES2 because it doesn't work anymore. I have disassembled the whole thing and the main probem was overheating/melting of the three power cables, coming from the driver board, to the motor. I could fix those (not using plugs, but instead solder them directly), but the driverboard itselve has at least two blown parts, show in this picture: Can somenoe tell me what parts those are? Number one could be a smd transistor, like those above the microcontroller. About number two, i'm not so sure, it's an smd part with six pins. Thanks in advance Fat Unicorn

My ancient sbuv3, very similar/same motor as solowheel, is (increasingly) misaligned, it balances at a slightly oblique vertical axis. Riding is uncomfortable therefore, even a little unstable, when compared to another EUC of the same make/model, which goes fine. Is there a mechanical adjustment inside the motor? Which side of the motor should I open? Do you have photos showing the inside? I suspect a loosened PCB. Or an accelerometer IC is subject to aging. I'm read that there are people who know this EUC motor: https://forum.electricunicycle.org/topic/13393-how-to-remove-pedalscranks-access-motor-on-solowheel-xtreme/ Thanks for any advice, Paul -
If anyone can shed some light on this I'd be most appreciative. I tore down my IPS Zero 260 because it simply wouldn't charge anymore. This, after a few stages of degrading performance (e.g. a one-off cutout at low speed, limited range, erroneous low battery warning, wouldn't charge past 80% or so, etc.). These occurred over a period of a few months of daily use. Thinking that I had bad cells (I don't know, just guessing) I decided to remove the battery pack and get an estimate to build a new one. I know it'll be tough to afford that but I hate being without my EUC. As I got into it I also checked all the connections and wires for any sign of shorts. Finding no serious wiring issues I decided to look at the board and this is what I found (see pics). Link to full resolution pics in my Google drive: https://drive.google.com/folderview?id=1ML7ZwkBCOBkzBhUFISRJnN_qxOSg1ZkY I'm certainly no expert but it doesn't look good to me. Could the corrosion and water damage seen in the pics be the cause of all my issues? Replacing the batteries will likely be prohibitive but a board repaired might be doable. But, I'd hate to do a board repair only to find out I've not solved the problems and that I'll still need batteries. Any thoughts? Also, if you know of anyone who could do the work please give recommendations. I'm in south Orange County CA. -
So , as you all know I’ve had issues with my ACM . @Rehab1 was nice enough to send me a brand new pcb but neither of us thought about the fact that my wheel is 67v and the pcb is for 84v. So my question is, is there anyway to have the firmware for 67v loaded on this board ? Or is there anything else I might be able to do this is a brand new never installed pcb ? @Marty Backe, @Jason McNeil, @KingSong69, @Smoother...any ideas guys ? Maybe somebody has a 67v to trade for an 84v ? Otherwise I guess I’ll send it back to @Rehab1.
