    How in the world do you program this spot weld module?

    I have just spent the whole morning trying to program this module. I figured YouTube would help, but no luck. I'm able to program the voltage and other parameters, but I cannot get rid of that "wait" on the screen. My understanding is that it should read line voltage. Any help would be GREATLY...

    Li-ion smart charger recomendation?

    I just checked out that link, and it seems like that's what I'm looking for. One disadvantage is that it will not discharge. Is this a problem, or do you know of another unit that has all the same options as well as discharge mode? Thx

    Li-ion smart charger recomendation?

    Well my plan is to purchase cells from China from a reputable supplier, but I still don't trust anything Chinese, so I will definitely want to test them all before I build a pack. I will eventually start a new thread about where to get these cells, but would like to hear where you get yours? I'm...

    Li-ion smart charger recomendation?

    Thanks for those recommendations. I'm totally new to this, so excuse my ignorance because I actually have no idea as to what I really need. I don't want to buy something only to find out later I should have bought another model because the one I bought is lacking an option. My plan is to...

    Li-ion smart charger recomendation?

    I'm sure there's 100's of unit available, but looking for something that will charge as well as diagnose 18650 cells. I've been reading some reviews about the Opus BT 3400, but would rather trust what this community recommends. Thanks in advance !! Dan.

    A2B Metro build

    The problem was that I was testing with 36 volts. Tried 48v and it now runs great. I'm using an aftermarket controller.

    A2B Metro build

    Made good progress, but having an issue. After a few hours messing with the phase and hall wires, I finally got a nice smooth rotation of the hub motor. The problem is that at high speed, the motor surges like it's losing voltage. For test purposes I'm using 3 lead/acid batteries. The battery is...

    A2B Metro build

    How many cells in your 14 series, and what is the total AH ? Also, how far can you travel with that battery pack? I would love to retain the "in-frame" battery because it makes the bike look so much better, as well as better weight balancing. Unfortunately using the batteries in the frame may...

    A2B Metro build

    I ordered a new controller as well as a new display. I'm located in Canada, so my resources are very limited. We couldn't even imagine buying a controller at Walmart ! LOL Here's the items I bought; https://www.ebikes.ca/shop/electric-bicycle-parts/controllers/c7240-gr.html...

    A2B Metro build

    Picked this up yesterday, a (2010) A2B Metro.I always wanted an electric bike and couldn't pass up on the deal because I got it cheap enough that I have room to put some cash into it. Supposedly the motor has been all rebuilt, but the batteries are toast. It's all complete, but my plan is to...

    What did I get myself into ?

    What did I get myself into ?

    The motor was rebuilt with new hall sensors, so it should be fine. I built a CNC mill from scratch as well as a CNC plasma table, so figuring out this e-bike shouldn't be impossible, Like you said, I will need to learn the basics.Using the original electronics is really not what I plan on doing...

    What did I get myself into ?

    Thanks for having me here ! I just purchased an e-bike, so this is my first post here and I will need lots of help because I am a total noob when it comes to E-bikes. I'm very mechanically inclined so I'm looking forward to this new project. I purchased an older A2B (2010?) bike but it's not in...
