What exactly determines the voltage and the amps of the battery. Is it the amount of cells put together or the individual cell capacity?

What liability insurance do you have?

i got an s866 screen and an foc controller but seller told me its not intended for scooter motors and only for geard motors of ebikes ? can you help me plz ...

Where do you buy quality cells?

I have to thank you for this video. I bought the docreate and just tested with .1mm x10mm pure nickel and copper sandwich. I had to pry the weld with a wire cutter to break it and each spot left copper attached to either end of a 18650 cell. I also found that this would securely reweld in many cases tabs typically found on Dewalt, Milwaukee and Ryobi battery packs making a single cell replacement far easier than breaking apart the entire pack. I guess I should try to draw the circuit in the Docreate and see if there is a way to increase the capacitance to allow deeper penetration of thicker materials. But the combination of .1mm cu and ni at 10mm wide is very sufficient in virtually all tool batteries.

excellent. thank you.

Thanks. Wish I'd seen this before buying the kerpu-like model I bought.

Hello, I live in Turkey. If I buy electric bicycle spare parts from you, can you send them to me?

you gotta use transmission pan sealant tranny fluid eats every other rtv out there has to say transmission fluid on it

Can I send my batteries to you guys to get this service done?

FOLLOW UP TO THE QUESTION WHAT HAPPENED WHEN THE BOTTLED BATTERY IS NOT CHARGING AND I AM PRETTY SURE THE CHARGER IS WORKING GOOD COZ THE CHARGER IS WORKING TO OTHER EBIKE AND SCOOTER

VERY EDUCATIONAL......THANK YOUUUUUUU I AM AN AVID FAN OF EBIKE ESCOOTER CAN I ASK YOU A QUESTION, I NOTICED THAT YOU DIDN'T PUT FUSE IN THE CHARGING PORT, I ASKED THIS QUESTION BECAUSE I MISTAKENLY SHORT CIRCUITED THE CHARGING TERMINAL AND THE RESULT THE CHARGER STAYS GREEN WHICH SUPPOSED TO BE RED AND WILL ONLY GREEN WHEN IT IS FULLY CHARGED. CAN YOU GIVE AN INSIGHT TO THIS PROBLEM PLEASE

speak slower, i gotta go to 75% speed. easy there ben shapiro

How is that supposed to be cheap?

We need a mid drive version of these bikes, those hub motors are not good offroad

It's a nice build, but by buying all those parts individually you will pay more than just ordering one off Alibaba, which I did ( and yes, HIGH-QUALITY). everything on this bike is almost the same except mine is a 95 mph (GPS) 15,000Kw 49Ah Samsung cells, 200amp Sabvatron controller, moto seat, KKE forks, and leather grips, all for $3300 to my door from (Domain electric bike company in China) bought in February and arrived May 12 only because it was a custom order.

TOP TOP TOP TOP !!!!!!!!!!!! Thank you man.

I showed my 14yo son this bike. Now he's wondering if he should save for a car or this lol

wow play back at 75% speed if you want to hear properly oh his soldering is bad you need to heat the wire so that it melts the solder unlike his which only sticking it

Stealth bomber... What a ripoff that was.

Excellent Video. You should do a fat tire build on a budget. Thank you

Informative but the fast forward speed and the fast talking makes watching it very annoying...

An "out dent"? I think you mean convex. Oppose to an "in dent" or concave?

Just a wild guess but Have you done this before Very Informative cheers 😮

Which model of bike Friday is this? Can it still fold with the mid drive installed?

Top quality!

Thanks for getting rid of the music...

Why don't you check the internal resistance of the cells before installation, only the voltage? It makes no sense to check the voltage itself.

Sorry but you talk to fast

Great information. Any info on the battery meter and the type of blue tape. Going to order on aliexpress as i am overseas. Is there a diagram to show how to connect both the 48 and 52v batteries

Great video… Do you know what the overall dimensions ended up being?

hi, don't you put foam to prevent the battery from moving in the case?

This is the most helpful video to mi Betsy, thanks a lot

My first battery build was a 42v 40ah. Abit scary to handle 😂

O muzica mizerabilă, n-am inteles nimic. Un mare dislike!

muted the sound. Much more relaxing

How to conect wires to battery like adding a controller can u make a video

how much do u charge to build battery

What a good video that was.

Had to go .75-speed.

A place i can buy elsewhere?

omfg How do I turn off the music?!??

Talk slower

you state you do not need to do the positives as no current, can i ask how you worked that out, current flows from negative to positives as amps are not used in a circuit but are returned, i have never seen like this before from any other battery builder.

This is what I need, I think, can you please tell me the physical dimensions of the pack, I have limited space 👍

It looks like you're holding the probes too close and a bit more current would be what the doctor ordered.... Nice video.

Start my 1st motor controls class In a week and a half. Thanks for all the helpful information. Anyway I can support your channel I will man. Thanks again

Finally installed, coupled with their 52V high discharge. What a sunrise of a ride. On a 2002 Norco VPS DH. Eats hills like pigeons do bread crumbs. Didnt install cadence sensor or brake cut offs yet. Marzo bomber 300mm front forks with dual torque arms installed, just had to file the drop outs a millimeter or so to fit wheel. just as they say, 45/50km/hr up hill no effort. Once more, a great product that needs no alteration out the box. wonder if they worked on new features (one wheel drive possibilities, rear light ...) for the next gen controller? Anyhoot, Fantastic product, easy install and loads of fun... Wow. Really surprising at how fast it gets up to speed.
