    Any DIY battery Gurus on the forum?

    Not after when it's passed through an electric power tool it ain't. That's when you end up gripping the tool not being able to release your grip. I actually did that once in my idiot youth. It was only because I fell over that I was able to pull the other wire out, break the circuit, and let...

    Any DIY battery Gurus on the forum?

    Thanks, that's getting closer. I've read but cannot confirm that they use Panasonic 18650 Battery 3200mAh 3.7V Li-ion 10A 3.6V Rechargeable cells (NCR18650BD). Hmmn, yes, tried that once in the old days when one used to hold the electrical cables for power tools into plug holes with...

    Any DIY battery Gurus on the forum?

    Says, Input: 220-240V But - Output: only 42V. I'd need 220-240V out. I'm guessing that I'd have to charge each battery individually, even though I could wire them up together. Needs thought. That's two strikes in one post. You must have been asleep in physic class, and home economics...

    Really? I thought 2 electrodes stuck into a potato and some lemon juice would do it. Don't suppose anyone makes a 240 to 240v charger?

    Any DIY battery Gurus on the forum?

    Bizarre. I did actually find my 4th Lime battery today, dumped by some bins. That would be me up to 230V x 18Ah if I wired them up in series (the aim was to power a bicycle sound system so, say, 4,140 watt hours?). I'm kind of intrigued where these are coming from as I don't see many thieved...

    "Conversion kits to blame in 40% of ebike fires, says London Fire Brigade"

    I saw one that had been burnt the other day. I'm pretty sure that molten aluminium dripping off the frames is going to cause other fires if falling on wood or fabrics. I don't know about specific alloys, but in its pure form its melting point is approximately 660° C. Should that be a safety...

    Doesn't look like any chip pan fire I've seen. (In fairness, many of these are e-scooters but the batteries are much the same).

    "Conversion kits to blame in 40% of ebike fires, says London Fire Brigade"

    So far. The bikes are still in use and so still have a potential to do so. I'm presuming there's going to be a curve that gets steeper as they age, then there's going to be the joys of fly tipped dumped ones, and exploding landfill. Thing is, what with the Tories cutting 1/3rd of the Police...

    "Conversion kits to blame in 40% of ebike fires, says London Fire Brigade"

    The proportion of fires I'd be looking at is relative to the proportion of bikes kept in houses. If they go off in the street, they're unlikely to hurt anyone. Guess how the neighbour who lives in the flat below you is going to feel about 200 gallons of water in their living room. Just out of...

    "Conversion kits to blame in 40% of ebike fires, says London Fire Brigade"

    I reject the idea that the high end stuff is "Chinese made". Apple stuff is made by FOXCONN who are Taiwanese working under contract for an American company. Likewise other good stuff made under contract for Japanese companies, like Shimano. I just don't understand why, if let to their own...

    "Conversion kits to blame in 40% of ebike fires, says London Fire Brigade"

    You have more faith in Chinese quality control and adherence to manufacturing standards than I do. I don't know about "inherently safe" though due to the duration and intensity of a battery fire. With private imports off AliBaba flooding into the country, how can this risk ever be stopped now...

    "Conversion kits to blame in 40% of ebike fires, says London Fire Brigade"

    How many deaths need to happen until it triggers the "something has to be done about it" feature in government? Technically, I think the way that politics works, it has to be 2,000+ deaths (as per 9/11), or 1 small, attractive blonde (as per Maddie, Lucie Blackman etc), or will a single...

    Bump. Is there a reason not to display the post above? I see a message, "The requested thread could not be found" and "Forb has not posted any content recently" ... while I can clearly see that I have. Why was it censored? Thanks.

    Any DIY battery Gurus on the forum?

    Looking at the results of people re-appointing car batteries, and how long they last on what are basically the same cells, I don't know if I agree with you. That's more just fearmongering than electrical engineering. I'd feel 100% safer reusing these than buying some new, cheapo, off the shelf...

    Any DIY battery Gurus on the forum?

    Yes, sometimes, rarely, living in a high crime area has some advantages ... ! Normally what we do if the company won't collect is break up any metal parts so that they can be recycled, e.g. when OFO went bankrupt and we ended up with a load of their yellow bikes being dumped, so with these the...

    Any DIY battery Gurus on the forum?

    Hi, Are there any DIY battery gurus on the forum? I live in a fairly wild part of town and over the last few months, I've found not one but three batteries that clearly look like they've been taken out of a Lime rental e-bike in the park I do volunteer work in tidying up. Bizarre really...
