BTN's Secret: Electric Bike Battery Replacement from RPE

BTN's Secret: Electric Bike Battery Replacement from RPE

Electric bike batteries need service, sometimes rebuilding too. Luckily, there’s a place in Vegas that warehouses for BTN bikes, and rebuilds battery packs for ANY electric bike. Sure enough, call them up if you have questions.

  1. Hi. I need urgent help with disassembling a single case ebike battery. The batteries won’t slide out of the case. I am visiting a country located outside the continent and without resources. Case is 390 x 110 mm c 75mm. Thanks for any help.

    Thank you young man for your valuable information, so wait until next gen bikes with next gen batteries before replacing older E Bike.

  3. This is our professional ebike battery eshop,welcome u view and give some advise https://www.wish.com/merchant/5d5b613c34037d42c721dfee

    RPE, isnt that the company that on their website thinks amps and ampherehours are the same?

  5. 3 haibike yamaha batteries , 2 years of more than moderate riding , we need to talk

    Great movie confirming much of what we see over here in Europe. What is your opinion on suicide chips integrated in modern e-bike BMS?

  7. I bought a battery from Sean ebikemarketplace.com. We corresponded thru email, cool to see him interviewed. My battery actually got lost in the mail and he replaced it. This is a good company. I think they got a great idea and they will only grow.

  8. I watched the unedited version of this and wasn’t impressed so I made some notes. This edited version might be better but I’ve spent to long on this already.

    OK has this guy got an real figures, stats etc to back up any of his claims with regards to training your batteries?
    Because I’m calling it.. can you smell it?

    Right, it think this guy know some stuff but other stuff he’s well off the mark or his words are betraying him.

    I’m not an expert by any means but in four+ years of working with lithium cells and learning about them I can point a few things out that I think I can better explain.

    I can’t be bothered to check all the thing he says some of its correct but some of its just odd as he contradicts himself with the correct answer.

    I think he should have had the questions before and then read it of script.

    Let’s look at his capacity vs current.

    You trade one for the other he even alludes to this after, manufactures characterise their batteries and make different models for different applications.

    It’s all to do with the way the chemistry is setup within the battery as well as the particle size of the materials used and then how they lay that down on the internal film on the anode and cathodes as well as the solvents used to suspend the materials.

    That then affects the internal resistance of the cells, the lower the resistance the higher the current but the lower the capacity so if you have a nice think coating you can get a lot of active material in there for capacity but then the ions will move slower through the thicker material thats then increased resistance so if you force them to high amps in either direction this results in heat.
    Thinner material coating is easier for ions to move which is lower resistance and less heat but also less capacity.
    The solvent also comes into play here as well as improvements in the solvents have an effect on the ease of movement of the ions.

    The energy density 18650 vs larger cells if you take the core out and work out its density then do the same on a larger cell thats the same manufacturing setup and chemistry it will be the same density the only difference in that the overhead of the shell / construction of the battery is different.
    So the smaller battery has more metal and air around it for a given volume vs a larger battery but there are potential downsides to this like for example heat, if your packing in the core material and your pulling max amps from it then there will be less surface area to lose that heat from.
    But if you have larger cells then you have less manufacturing costs, as to get a certain capacity takes less cells which means less welding, so reduced costs.

    So all cells are a balancing act for any number of reason I’ve just given or other things I haven’t mentioned.

    If you really want max capacity and current then your best using squared cells with as thin a wall around the cell as you can get away with as then you have no free air around the cells and you can maximise their density but then you have to watch that heat. And if you’ve gone thin shell with plastic you then have a potential safety issue if that wall gives out between the cells thats then a lot of energy shorting which you guessed it. FIRE! 馃檪

    I could go on but you get the idea I hope.

    But please if this guy has data on the first thing I said publish it, thats the only thing I can think should be of interest to anyone whos interested in lithium ion tech.

  9. Just sent my old battery to you for rebuild babyyyyyy!

  10. thanks, it is very good video

  11. I didn’t know such a place existed in Vegas! I’ve been doing all the repair work on my ebike for so many years I never even bothered looking a bike shop dedicated to ebikes. Cool to know there’s such a place locally!

  12. charge on man ,,,,,,,,,,,,,,,,,,,,, good explanation of cell types

  13. Great to have you folks around! Another area which needs help is dog grooming clippers. A lot of battery rechargeable clippers die prematurely. We pay a fortune for these – tiny cordless clippers running $80 – $100 each, and not holding a charge long, and dying prematurely where they don’t run at all. I’m convinced this is due to faulty battery issues. I wonder if you would consider selling those battery cells directly – maybe 1 or two to replace my clipper ones?

    Like 110 amazing good video thanks for all the information 鉁屸潳from Wildeys

  15. Scott PerfectlyLonely February 24, 2021 @ 10:31 pm

    Thanks for the resource.

  16. Ebike Marketplace February 24, 2021 @ 10:36 pm

    Thanks so Much for the Video it looks great!!!

  17. That’s cool…. I have heard of relying on manufactures and warranties for this, but its so much better to have 3rd party support that doesn’t charge an arm and a leg and can work with literally every brand out there!

  18. Hi, i was told that it is quite difficult to rebuilt a Bionx battery. There a quite a few issues doing it. Can you give me some advise ? Thanks. Great vid茅o.

  19. Steven K McKendall Sr February 24, 2021 @ 10:40 pm

    Hello. Can you please explain &/or do a video in layman’s terms. on what an Electro kinetic cell battery is, and relevant info, as pertaining to such?
    Thank you

  20. DKL Veh铆culos El茅ctricos DKL February 24, 2021 @ 10:41 pm

    Cool this is excellent, is it really true that the future is 21700 cells???

  21. Blue Monkey Bicycles February 24, 2021 @ 10:45 pm

    Support for old eBikes can be tough, but it’s great to have a resource like RPE around. How big of a battery is too big though? Honestly, I can’t decide. Most of the time I’m fine with a 36v 14Ah, but I think I’ve adjusted my habits to fit the current tech that was available. What do you think?

  22. Sean rebuilt my old A2B Metro pack to 21Ah and doubled its range from stock. Great service! I highly recommend ebikemarketplace.com
