    EM3ev WARNING - abysmal customer support.

    To be absolutely clear. A chargeback was initiated by the buyer. We chose to immediately agree to it and not fight the matter, which is classed as a refund. We didn’t refund prior to the chargeback as nobody had contacted us for weeks prior to the chargeback, neither was any effort made to put...

    em3ev.com - UPDATED August 2022 - ISSUE RESOLVED

    Hi Dean, I’m very happy we could get the matter resolved. I’ve let others manage aspects of the business and haven’t put enough attention on the retail side of things in recent times. Frankly the combination of parts that we supplied as a kit (to you and others) was rather on the extreme side...

    EM3ev WARNING - abysmal customer support.

    Thanks Neptronix. Sorry, didn’t consider that details were included. There isn’t much you can do about people abusing CC’s unfortunately. Whilst CC companies are happy and willing to blindly listen to a 1 sided story, with no proof or communication with the supplier, then people will continue...

    EM3ev WARNING - abysmal customer support.

    I agreed to refund after the charge back. The money was already pulled as far as I know. Should be fine.

    EM3ev WARNING - abysmal customer support.

    For clarity, here is a list of the emails received across our company regards this order 27380. you make up your own mind looking at the timeline of what actually occurred if we were unresponsive (or not) and how much effort was really put into finding a resolution to an issue (regardless of how...

    EM3ev WARNING - abysmal customer support.

    Not replying to an email is wrong. Nobody denies that. However, the situation here is actually this: 1. Numerous emails were exchanged with Moon that dealt with the shipping. No effort was made to reach out again to her when Joseph failed to respond to 2 emails sent within a 2 day period...

    em3ev.com - UPDATED August 2022 - ISSUE RESOLVED

    We stopped supplying Mac kits as there were too many issues of 1 sort or another, we stopped offering them some time back (due to situations such as the OP). We stopped supplying the Ebike Frames and the high power kits to go with them too, for similar reasons. These products required too much...

    EM3ev WARNING - abysmal customer support.

    Apologies that Joseph missed your earlier emails. You sent 2 emails previously in late April, 2 days apart, that were not responded to. There was no more emails from you, until you put in a charge back on your credit card recently. You did not contact Moon during that period, whom you had been...

    52V Battery wont charge past 80%

    Measure the voltage of the charger when it's not connected to the battery. Measure the voltage again, when the charger is connected to the battery. The voltage should be about 58.8V in the max setting when not connected to the battery. If the voltage drops to around 55V and stays there, when...

    BBSHD, Help with 08H code

    If you had of further discussed the matter with our support staff, they would be happy to suggest how to get the issue resolved on your out of warranty motor (and we did respond and were in discussion with steps to follow, nor did we refuse anything). We are happy to assist with any customer...

    BBSHD, Help with 08H code

    That's quite right. Doug has been repairing the BBS motors for years and his repair service is very reasonably priced.

    New Samsung cell 33G

    33G are an EV grade cell that are produced in China by Samsung. Yes they are produced by Samsung, and we purchase from legitimate Samsung supply channels. They are supposed to have good cycle life and if charged/discharged to 4.1V/2.75V are supposed to last 8 years plus in an EV Car application...

    Samsung 21700, 3Ah , 30A discharge.

    There is talk of a 48G 21700 from Samsung. It's an EV grade/type cell, and I'm guessing it will be a bigger version of the 33G cell that is currently available (~3.15Ah, 18650, not a high power, 2C cont. 3C max, fairly high energy density but with a relatively low price point). I'm guessing the...

    Samsung 21700, 3Ah , 30A discharge.

    Well Lock, I have observed your various posts and links to cool stuff for years and I commend your good fight :) I like to think we're on the same side here (been supplying Ebike parts for years and manufacture our own battery packs) and whilst I am still driving a gas car, I am very sure, my...

    AllCell Battery Fire

    Most BMS should have no problem handling some regen current when the battery is at a low state of charge. Most bms are a 3 wire type, that have a seperate charge and discharge cable. 2 wire type shares the charge and discharge on the same cable. 2 wire type requires more mosfets to handle the...

    Dogman Dans E bike burns his house.

    OMG, that's nuts. Very happy to hear that you've managed to make the best of a really bad and extremely tough situation, and that nobody got hurt. My heart goes out to you and your family. Hope the trauma of it all can pass soon and you can get back to normal as soon as possible. Things like...

    AllCell Battery Fire

    Apologies if I was a little premature and critical with some of my comments. Battery packs going on fire is every pack assemblers worst nightmare. I have no skin in it, but at the same time, I wouldn't like to see a reputable company getting bad press, when the details are unknown. At the same...

    Samsung 21700, 3Ah , 30A discharge.

    Well apparently, yeah these cells can genuinely deliver serious current without breaking a sweat. Whilst I'd say 30A per cell might be pushing it, but if they can do 15 or 20A without being stressed, that is already very impressive and is better than any 18650 cells that are readily available...

    Samsung 21700, 3Ah , 30A discharge.

    No, not MCG. Not really into blowing my own trumpet or grandiose ideas about myself. Saturday night there is it? Had a few? Anyway, thanks for the feedback and opinions, I'll certainly bear them in mind. Have a good weekend Paul

    Samsung 21700, 3Ah , 30A discharge.

    They are intended for power tools, the same way the Samsung 25R is intended for power tools. Not sure what is wrong with that statement or why it seems to bother you. It doesn't mean they can't be used on an ebike, it's just a statement of their intended application. I asked the question if...

    AllCell Battery Fire

    Sure, not an invalid point and that is only 1 of several points made. I also stated that i don't know the specs of the battery and I'd be happy to be proven wrong (I've since had a look and it seems like their typical 36V packs are bigger than i thought, so my point is likely invalid). The...

    Samsung 21700, 3Ah , 30A discharge.

    This cell is intended for power tools. Other samsung cells in this format will come with higher capacity, but lower discharge rates soon. I'm aware of this cell and can possibly get some, but my thoughts were that it wasn't great for most users, as the capacity is no more than a 30q, and the...

    AllCell Battery Fire

    What model of Allcell battery are you using, what is the capacity? Some observations: 1. I don't see a battery fire, as in, I don't see cells that have gone into thermal runaway and burnt. I see a burnt out BMS, maybe some burnt cables, not more. Happy to be proven wrong. 2. Your practice of...

    Inter vendor squabbles - luna cycle, em3ev, ebikekit, etc

    I'm sorry, but I've got better and more productive things to do with my time. There is a lot going on with the business, my family and new products that need to be worked through, so I really don't need to be getting into all of this any more. That time and energy that I've wasted of late, was...
