    Close To Total Failure?

    I'm sorry, I am not sure what you are referring too, but I will check my post history just to be sure. The last post was about what bike batteries are good to buy. I did not see a question, but more like straight info in the response, which was nice. I did not know it was customary to always...

    Hi there. Will any torque arm do for this bike? Any particular recommendations? I am pretty sure the forks are aluminum alloy. Is a torque arm really needed? Thanks in advance. https://imgur.com/a/lGhE68g

    Battery Prices Have Plummeted, Except For Ebikes?

    So let me guess, there are no plans to bring battery production into the U.S., that is except for Musk's car battery only factories?

    Battery Prices Have Plummeted, Except For Ebikes?

    https://news.wttw.com/2020/01/02/falling-battery-price-transforms-economics-green-energy Whats Going On? Even if the extra cost is calculated from china shipping and the more stringent battery shipping rules, it still seems like batteries should be a lot cheaper than they are now. I probably am...

    Lifepo4 7+years old and the Nail Polish Smell

    I think my lifepo4 has finally bit the dust. I can't test these things because i'm visually impaired. I have it stored in an ammo can and when I open the can it smells like nail polish or something of similar potency. It's always smelled like that from what I can remember but perhaps a bit worse...

    Elon Musk's - Hyperloop

    I wonder how quickly an emergency stop could be achieved. Not sure how helpful a P-wave sensor system triggering emergency "brakes" would be. I'm sure they would have to design it where a train passing through a certain magnitude earthquake would survive.

    Just Like That, LeBron/Lakers

    Don't hear about any big names coming up through the ranks as much. Its starting to feel like the period just before Jordon retired. After Jordon retired the NBA got boring for a while. With Kobe gone, and LeBron to follow suit at some point, things might get boring until another super star...

    Earthdas Graphene Battery Charges in Five Minutes

    Sounds cool but I think for it to really hit the ground running, you would at least need a lower setting for charging so you could switch to either one due to the lack of 40 amp+ breakers/outlets. Would be awesome if there was a 5 min @40 amp mode and a 20-40 min mode for 15 amp...

    should you Toss a Leaking LifePo4?

    ' I don't care so much about fire, but if its poisonous or carcinogenic; touching it or off gas inhalation, etc. Yeah i skip on the eating it part, but things in micro doses can kill u, sometimes years later.

    Thread for new battery breakthrough PR releases

    When I first read up on this corner of the forum I was hyped at all the new technology "just around the corner". Now when I read I realize its a tease and that most of the stuff will be dropped or will take 10+ years. Honestly I should be reading the Cryogenic forums to see when I can be put...

    should you Toss a Leaking LifePo4?

    Or should u ride it until it stops working? The reason I ask is because I am afraid that the battery might be toxic if its leaking. I "think" i smell a sweet smell for years now and yet the battery still works and the red LED'S all go solid after a full charge. Could I be smelling the plastic...

    Ping Battery Charger: Potentiometer?

    I am wondering if the Ping Battery 5A Charger has a Potentiometer. My voltage has dipped down to 41.7 Volts and that isnt enough to trip the BMS, I am wondering what else it could be other than normal wear? All the Caps look ok, none bulging that I can see. Any Ideas? I believe the voltage is...

    Anybody have experience with Sun-Ebike.com?

    Their LIfepo4 batteries are pretty cheaply priced. Would they last? Why are other Lifepo4 more expensive?

    Potting Batteries, Thoughts and Experiments

    I have a few questions, if you don't mind. 1. How many cycles for the life of the batteries? 2. Is it safe to series or parallel the batteries when they are at different parts of their life spans? (if you get a brand new one but have been using another one for over a year or more. 3. Is there...

    Kickstand Recommendations?

    As many of you have experienced, ebikes can be on the heavier side. My kickstand finally failed to where it wont hold the bike up anymore. I'm thinking about getting one of those two legged ones, but I am not sure which one to get. Any suggestions? I need it to be more heavy duty than a...

    I think I have a Short

    Update: I opened up the cable and found two wires disconnected. One of these was for power and the other was the smaller hall sensor wires. I didn't get a chance to solder, I instead used some connectors for a temporary fix. The cord lucks ugly but at least it works. Thanks everyone who gave...

    I think I have a Short

    The Red Circle is the Problem Area. By bending it further where there is already a kink it causes the bike to function normally.

    I think I have a Short

    So I found out where the disconnect is on my Ebike. It is on the cord that connects to the motor. The company I bought the kit from has long since disappeared. It was from Amped bikes, their 500w-750w DD hub motor kit. So if I cant find a replacement cord (it has connectors on both ends) then I...

    I think I have a Short

    So today when turning on my ebike I get power for a second then it cuts out. I get power instantly when I reapply the throttle. The strange thing is when I turn the handlebars right I get full power.. to the left I get no power and to the middle I get one little spurt and then a cut-off...

    Rate My Multi-Layered Ebike Security Plan

    For many years now I have only locked up my bike right where I can see it out the window at a cafe, and if I can't see it and I need to grab a couple things from the store, I run in the store really quick and try to take no more than around 5 minutes. I have now made my ebike my main form of...
