    Dual capacitor battery spot welder under 100.00 usd

    Thanks my original one is still working perfectly so far btw, the one i did the mods to, . But as it was cheap I keep expecting it to fail, so even though this was an accidental find and I thought 999Zip might be interested, It was so cheap I was thinking of getting it as a spare. But based on...

    Dual capacitor battery spot welder under 100.00 usd

    Took a while to find the thread again, I'm new to forums, but finally worked out how to do it (easy and obvious with hindsight). Until now I have mainly been using the alert bell, but because I have been busy building and not posting, the bell ran out of replies for me to go to. Wasn't looking...

    Don’t recharge just replace

    I remember when they introduced USB sockets and said it would be a global standard..... And was for about five minutes. then came USB B and USB C, and the plug part was something specifically intended to be simple and standard. To standardise phone changers. So I dont think it will ever happen...

    How do you convert a pedal assist ebike to throttle ?

    Well I am still very much a beginner at this, But I found by simply not connecting the pedal assist wires, It worked perfectly. This bike already had a throttle, which saved fitting one, but while fitting the new controller, I experimented with a throttle from a scooter that I had laying around...

    Honestly it was never about speed in that sense, just enough to be practical will do for me. Well good new and bad news, I got the new controller connected up and working in no time, surprisingly easy....... The bad news is the new controller is fractionally bigger than the old one and will...

    Yeah it has self learning wire, and this video shows me how to fit more or less an identical controller, and how to fit it, and how to use the self learning wires.. video on how to fit almost identical controller So I think it's fairly straightforward, unfortunately my bike has slightly...

    Yeah I'm guessing that the LVC in the controller cut the power at about 3.0 v (under load, uphill) which is ok, It immediately returned power when I throttled back, As it's the first time I have experienced that, I was pleasantly surprised how it worked. Amen to that, :)and I wanted to know the...

    Oh ignore the last question unless you want to chip in, because the bike just answered it for me. By that I mean the first part of my test route is up a gentle hill, the bike started cutting power unless I throttled back. Once the slope/hill leveled off it was fine, so I called that done, came...

    I was a mountaineer btw, and a few years ago, these videos went viral on a new sport called Liquid Mountaineering. (see video) Liquid Mountaineering Our local climbing club convinced people they were real, and used to tell them we were going to Snowdon National Park do a bit of climbing and...

    Not quite. Now I will end up with two 36v BIKES both with one 36v battery in each one (I do now have several 36v batteries but never even considered putting two in series, BUT IF I DID then 2 x 36v in series would as you say be 72V. One bike that was originally 24V will have one 36v battery...

    First to clarify I'm not modifying the one that was 36 volts at all, that is left exactly as it was. The work I did on that was to build a battery (several in fact) from various donor batteries, they are all 36 volts so direct replacement for what was there. And been doing various mechanical...

    Thank you so much, a very valid point, but while no one has mentioned safety at all, I did consider it. First, to directly answer your question, yes first it feels that it will do it no problem. To expand the answer I also have some logic that I considered. 1) Like most folding bikes it only...

    Hi Sorry for the slow reply, I missed your post, just seen it. Well its and Electrobike MK2 made by a UK company called ASBikes.co.uk. (Still in business) They bought out a a newer version the MK3 which is 36 volts, but according to them its not viable to make this one 36v but from what I have...

    New to battery diy ?? Read these VERY INFORMATIVE documents

    Well I unplugged the power assist cables from the existing controller, and it did not make any difference at all. So obviously power assist still did not work, but twist and go throttle still worked perfectly. So the bike itself doesn't need this feature. And therefore if this is not even on the...

    Thank you..... I suspected this was basically crap, but was not sure ( I mean it's probably 10 years old, but I doubt even bikes of that age would be using analogue potentiometers as throttles..,..... But I could of been wrong). The throttle does not have any meter of any kind on it, in fact...

    How do you convert a pedal assist ebike to throttle ?

    Thanks doc, Well def cheap enough, that supplier don't ship to uk, but I expect someone here sells them I'll look for a uk supplier, if I'm not sure Ill come back to you with a link. Had a quick look on e-bay, progressively shortened the spec trying to find it or something similar, but not...

    I had asked the bike manufacturer for some information on the controller and motor. Well, basically they misunderstood and thought I wanted them to convert it to 36v (like their newer MK3 model). But in the process of saying its not cost effective with labour, I picked up this snippet. "As...

    How do you convert a pedal assist ebike to throttle ?

    Challenge accepted LOL :) Well sort of, I'm in the UK with our overly restricted e-bike laws.. But I have a VERY OLD 24v folding bike that has either power assist (pedlec) or twist and go, selected by a button on the handlebars (no longer legal on new bikes but this bike predates that law, so...

    Great thread, very interesting. Obviously if I replace the controller I wouldn't need this, but clearly it would work fine. He is actually using it for the output to the bike, (and getting by), I was only going to use it to modify the charger to charge a battery that was non standard from a...

    Hi again (Sorry) Spent literally hours, trying to find a suitable 36v controller, not given up, but like everything else e-bike related, it's always ends up a bit more problematic than expected. I did put the controller back in the bike and try with a 2x 12v SLA batteries, and it wasn't too...

    OLD PAS BYPASS HACK, ages ago, I saw that someone took the wire that should go to the PAS sensor, and basically fitted a new PAS sensor on the front wheel, (think he used a speedo sensor from memory ?) instead of the original sensor the crank housing. so if the bike was moving, it thought you...

    LOL, Blowing things up seems normal for this game. Personally I try and avoid it (I can't really afford it). That said once I eliminate the basic obvious problems I'm serious about giving this a go, Now I got the controller out of the frame, I'm trying to work out what controller I would need to...

    Yeah they are a more realistic price the one in the diag I found cost a staggering amount. Thank you. Not sure of the controller spec, like the other 24v folding bike the controller is built into the frame, and TBH I thought I would leave well alone, as they are a real pain to get out, but I...

    How to Revive a Dead battery that was sitting for a couple years

    Thanks, did the run again, obviously more overall decrease but this time the max variation was only .04V (all round about 3.75 to 3.79) so looking good at least when resting. At least it's useable, so have not wasted my time, prob call this one ok, but will do a few more trips with it the get a...
