    LiFePO4 battery packs in series (Discharging and Charging)

    I tried to set up voltage monitoring through my Arduino and a voltage divider but realized I can only measure one batteries voltage at a time with it, since if I were to try and measure two batteries at the same time (which I definitely did not do) while they were connected in series, I might...

    LiFePO4 battery packs in series (Discharging and Charging)

    Thanks for the reply! I actually did buy a 36V BMS for exactly this purpose but I later thought that putting cells with different internal resistances and potentially even different capacities under the same BMS was unwise. I like the triple voltmeter idea (provides peace of mind), it'd be...

    LiFePO4 battery packs in series (Discharging and Charging)

    Hi everyone, I'm running a bit of an odd configuration for my battery setup currently and I'm hoping to run an even odder one! What I currently have is 6 tenergy 12V 15AH packs (each with their own seperate 4S BMS), I connect 3 of these up in series at a time for discharging on my 36V...

    PAS assitance failing?

    It's obviously not critical but a pit of an annoyance. I'll check the connection again, but I did before and didn't see anything wrong. Is it possible that the sensor to sense angular momentum to kick in the PAS are faulty?

    PAS assitance failing?

    Hey, I have a three level PAS 30% 60% 100% pedal assist that was on the fritz and then stopped working altogether. Whats strange is the cruise control on it still works as well as my throttle. Any suggestions??

    Spoke Strentgh (My spokes are breaking like mad...)

    Hey guys, it seems like everytime I hit the throttle/go over a bump a spoke breaks...! It's annoying as hell, and I want it to stop :P! What are the solutions, is my wheel just built like crap or is this something everyone experiences with their ebikes? Are there any one piece solid wheels...

    Velec e-bike "350W" Motor

    I bought this bike secondhand, I'm not impressed with the speed or range of the bike, Im going to get 1-2 ping 48V 20AH batteries and a new controller (crystalyte?), I want to know about the abilities of this tiny motor, I have no respect for it whatsoever... If I hook up a new 48V controller...

    Please help me push the limits of whats possible with ebikes

    Thanks for the quick responses. A Semi- or fully recumbant would make me nervous I think it would attract more attention from trafic cops. Same deal with the trailer but a little less so. If possible I may go with the trailer. Also im wondering how effective pedaling can be in saving energy...

    I have a need for an ebike that is pretty ambitious 230lb/105KG Rider 160km/100mi route mostly flat no stops Desired speed 50km/h 31.25mi/h constant with decent pedaling What kind of bike would I need to accomplish this feat I realize it's sort of on the edge of what possible. Budget is up...
